Rather than writing another eCommerce SEO guide when there’s already so many out there.
I decided to do something a little different.
Using a mixture of manual research and a simple custom-built scraper, I’ve spent the last month auditing 1,200 sites to give you a data-backed analysis of the biggest SEO mistakes.
Before we dive into those mistakes, you’ll need to understand what we’ll call the three key page-types:
These are usually the main pages to rank because of the high buyer intent i.e. someone searching for “buy sofas online” (category or subcategory page) is more likely looking to make a purchase now than someone searching “small room sofa ideas”.
This also simplified our research, as we didn’t have to review every page on all 1200 sites, which could result in tens of thousands of pages on a single store, in some cases.

With that said, let’s dive into the mistakes…
- 1 Title Tag
- 2 Meta Description
- 3 Category Pages
- 4 Product Pages
- 5 Internal Linking
- 6 Site Speed
- 7 SSL
- 8 URL Structure
- 9 Thin or Duplicate Content
- 10 Data Accuracy
- 11 Final Thoughts
The title tag is an SEO basic and essential, which is usually set automatically by virtually every eCommerce platform. Hence why, only 2 websites out of 1,200 had none set at all.
Yet, out of the 1,198 that were using them – only 107 had fully optimised them across the three page types we checked.
There’s two types of under-optimisation here and one type of over-optimisation, which we’ll cover in the mistakes.
First, let me explain what a title tag is for beginners:
A title tag is (…you guessed it) the title of the page, which will be shown within search engines. It’s one of the more important onsite factors, and should be optimised for keywords you’d like to rank for.
I’ll explain how in the following two title tag mistakes…
Mistake #1: Not Using Modifiers
eCommerce sites usually consist of too many pages to manually optimise every single one, instead you use templates to optimise pages fast.
A default template for a product page may be:
[Product name] – [Shop Name]
Which for a website named “Lion Zeal” selling an Audio Technica ATR2500 microphone, would be:
Audio Technica ATR2500 – Lion Zeal
Keyword modifiers are words we add to this template to extend the keywords we’re optimising to rank for. In short, we need to use words to have any chance of ranking for them.
In online shops case, these will usually be words like:
Putting this together, our example title tag (following a template) may look like:
Buy Audio Technica ATR2500 Microphone Online – Lion Zeal
We’ve added the modifiers “buy”, “microphone”, and “online” in this case to increase the number of keywords we’re optimised for, such as:
- Buy Audio Technica ATR2500
- Buy Audio Technica ATR2500 microphone
- Buy Audio Technica ATR2500 online
In the above example, this template would be valid for all product pages selling microphones.
This same principle can (and should) be applied to category and subcategory pages.
Our research showed only 107 out of 1200 sites (8.92%) were using modifiers in their title tags on all 3 page types. And a little bit higher (162) if looking at the product pages only, which adds up to 13.5%.
This is a tiny minority of sites for something so simple, yet beneficial to your traffic. It is extremely simple to rank for “buy Audio Technica ATR2500” compared to “USB microphones”.
Let me give a real example:
Mistake #2: Keyword Stuffing
On the opposite side of missing keyword modifiers is optimising too much. Suitably named “keyword stuffing”, it’s where webmasters deliberately write as many keywords as they can in an attempt to gain SEO benefits.
An example from our study:
Cheap Beds & Bed Frames | Buy Affordable Beds Online | Time4Sleep
In the above example, if we count the singular and plural of “bed” as one word, this title uses it 3 times – which is overkill.
They’d be better with:
Buy Cheap Beds & Frames Online | Time4Sleep
Here’s what we’ve changed and why:
- We’ve removed “affordable” as it’s a synonym for “cheap” therefore not needed
- We’ve changed it from “Bed Frames” to “Frames”, as the page and title is already on the topic of beds
- Finally, we’ve shortened it into one simple title which leaves extra space for a call-to-action e.g. “Free Delivery”
There’s a difference between using modifiers to better explain the page while expanding the keywords, and overdoing it i.e. keyword stuffing.
Here’s signs you’re on the over-optimisation side:
- You’re using multiple keywords separated by a | character
- You’re repeating words unnecessarily (in the above example, most sites write “Beds & Bed Frames”, so it’s probably fine)
Our research showed this was much less common with only 202 out of 1,200 sites repeating keywords in the title tag (16.84%), but still worth noting when advising on the importance of optimisation.
Below the title tag, you’ll find the meta description, which as the name makes clear, gives a description of the page.
Here’s how it’ll look in the SERPs:
This is another fundamental part of the onsite SEO process, and very easily fixed.
Mistake #3: Not Optimising
The most common mistake here, like the example above, is not optimising the meta description at all.
Of the sites we analysed, 244 of them (20.34%) had blank or non-set meta descriptions on one of their 3 pages in the study.
9.25% (111 sites) were using an identical one on across least two pages.
And 7 of 1,200 (0.58%) had descriptions of more than 158 characters set, which is likely too long to be shown.
If we use the above three issues as our benchmarks of a bad meta description, after removing sites with multiple issues, 291 had issues. That adds up to 75.75% being correctly optimised – ignoring CTR, as mentioned below.
When your meta description is setup incorrectly, a random sample of text that’s most relevant will be shown, as clear in the example further above.
Or your page/product description will be automatically used by your store platform, which isn’t optimised for clicks or keywords, and may be invalid (multiple sites were inserting HTML in their meta description).
Similar to title tags, the solution for this is templates.
Here’s an example meta description from our research:
Buy Matcha green tea powder online from Kanuka Tea. Top Ceremonial Grade. Free UK delivery. Buy now!
Presumably, they’re doing this with a template for all their tea’s. In this case, the template would be set to:
Buy [Product Name] online from [Store Name]. Top Ceremonial Grade. Free UK delivery. Buy now!
Though, if your title tag is already set to “Buy [Product Name] Online”, then you may want to use a different template to mix this up. Such as:
Shop for 100% Organic [Product Name]. Top Ceremonial Grade. Free UK delivery. Buy now!
The meta description here should include a few additional words you may want to rank for, in this case, presuming the product is Matcha Green Tea Powder:
- Matcha green tea powder shop
- Organic Matcha Green Tea Powder
- Ceremonial Grade Matcha Green Tea Powder
- And other similar variations
More importantly though, and this ties in with the next mistake, it needs to generate clicks.
Mistake #4: Not Optimising for CTR
Aside from keyword relevance, which is a necessity, the most important factor of the meta description is that it’s optimised for clicks.
This is commonly referred to as clickthrough rate (CTR) optimisation, meaning making changes to increase the percentage of people that clickthrough to your website from search engines.
Only 286 sites in our study (23.84%), were optimising their meta descriptions for CTR across the 3 pages we checked (per site).
There’s a few common practices to achieve this:
- Include a call-to-action that urges readers to click e.g. Browse our collection of living room furniture sets online today!
- Capitalise the first letter of key words e.g. Free Next Day Delivery
- Include features/benefits of your products and service such as free nationwide shipping, next day delivery, guarantee’s, discounts, etc
Take this example for a toy store selling Batman LEGO on this subcategory page:
A1 Toys Store is an independent UK toy specialist. We stock anything from limited edition collectables and comic con exclusives to Minifigures. Featured brands include WWE, Power Rangers, Transformers, My Little Pony, Star Wars and many more!
Firstly, this isn’t optimised for Batman LEGO specifically. Secondly, it’s too fluffy with information and not captivating enough to encourage you to click.
Here’s what I’d write instead:
Buy the Official LEGO Batman Movie Sets. As seen in the box office movie. Free Nationwide Shipping. 14 Day Returns. 100% Secure.
These small changes lead directly to more traffic to your site, and indirectly, as CTR (clickthrough rate) is also a Google ranking factor.
Bonus Tip: Not Including Emojis
One simple trick to stand out further in the SERPS (search engine results page) is to include emojis in your title tag and/or meta description.
This is unlikely to directly increase your rankings, but it’ll certainly increase the clickthrough rate and therefore traffic. Which arguably may influence rankings.
Google can be a bit picky about these showing sometimes, but to add one is really simple, just paste in the emoji when setting your title tag or meta description.
Our data showed 6 out of 1,200 sites (0.5%) were using an emoji in their meta description, with all of them using simple ticks or arrows to draw attention to features/benefits.
The next category of problems occur on the category and subcategory pages.
These are key pages for SEO as they allow you to target keywords that you simply can’t on the product pages.
For example, if you’re selling computer accessories, you could rank for a product name (e.g. “Buy Logitech MX Master 3”) on the product page. But what if you want to rank for “Buy Logitech Mice Online”? Or “Buy Gaming Mice Online”?
These are where your subcategory pages come, which allow you to filter your products to create content and pages for certain options.
Mistake #5: Not enough categories
One mistake many stores make is not using enough categories or subcategories. Now, I don’t have specific data to share for this, so you’ll have to take my word for it.
But here’s a couple surprisingly skipped over ideas of how you can increase the number of categories:
- Create one for each manufacturer e.g. on your computer accessories store, you could have one for Logitech, Razer, Microsoft, etc
- Create one for each room e.g. living room furniture, kitchen furniture, bedroom furniture, etc
Aside from that, you’ll want specific pages for any unique but highly searched type of product like gaming mice, in the above example.
Mistake #6: Not Writing Enough
Once the categories or subcategories are in place, you need a sufficient level of content on these pages to rank them.
Unfortunately, there’s no clear cut answer of how much content is the right amount of content. The typical SEO answer is “slightly more than the average of your top competitors”.
Our study showed, the average number of words on category pages is 134.54, and for subcategories is 105.90.
The problem, however, is that 152 sites (37.35%) had no description on their category pages, and 501 sites (41.75%) had no description on their subcategory pages, aside from their product lists – which counts for very little.
(Note: Only 407 sites were using category pages by the definition we’ve followed in this article, where the primary purpose is to link to sub-categories)
The solution is, of course, write more quality content. Not filler content. But content that leads closer to the sale.
Remember: Your category or subcategory pages may be the first page they ever visit on your website, what will they need to know before they’ll be ready to make a purchase?
- How is your range of products selected, manufactured, etc?
- Why should they buy your products or from your website?
- How do these products work? For example, if you’re selling custom printed advertising banners, you should explain the steps and how it’ll work
- Delivery times
- Why your pricing is lower or higher
- And anything else someone would ask or question before purchasing this category of products
Be careful with placement though, you don’t want to get in the way of browsing products.
Generally, you’ll show the essential information above the products – this will usually be short. And the rest will be either below the products/subcategories list or below the essentials with a “Read More” link to expand it.
Mistake #7: Spammy Tactics and Low Quality Content
On the opposite spectrum of not having enough content is having too much, usually extremely low quality with spammy tactics to mask it.
Now, I’m addressing this as a mistake because I think it is. However, I’ll be honest, I doubt the websites utilising these tactics are having issues. It’s just not a great long-term strategy.
Here’s what I’m referring to:
Content that is useless and boring to your potential customers, added to the page solely for SEO benefits, then hidden with techniques like:
- Extremely small fonts
- Multiple “Read More” links which expand the content. One is normal, multiple is excessive
- No use of images, videos, or any type of media to make the content more interesting – just huge chunks of text inserted at the bottom of the page or under a read more link
Again, that doesn’t mean these tactics don’t work, it’s just not as great a user experience, and not thinking long-term.
If your content isn’t intended to be read by an actual potential customer, it probably shouldn’t be on the page. For example:
As for how to create great content, treat your page as a potential buyers first impression of your business, what do they need to know? As explained in the previous mistake.
The final type of page we focused on in our research is product pages, the pages that list a single product for sale.
In most businesses, there’s going to be benefits from ranking these pages for the product name or “buy [product name]” keywords, even if the volume of searches for these are low.
Unfortunately as clear in the title tag/meta description research, only 8.92% of sites had both fully optimised on the product page we analysed.
Further than that, there were four key mistakes that stood out:
Mistake #8: Short (or Non-Existent) Descriptions
As explained above, without content, you can’t expect to rank in Google. However, many stores have as little as a sentence, or worse nothing, written for their product descriptions.
The average length in our research was 68.94 words, yet 352 sites (29.34%) had zero description, and 657 sites (54.75%) had less than 50 words.
All of this makes sense when you consider some stores list hundreds or thousands of products, but that’s like avoiding training your sales team about your products because you have too many.
From both an SEO and sales/conversion standpoint, content is not optional on your product pages. Therefore the real problem becomes, how do you create amazing content for a single product?
Here’s a few ideas:
- Have bullet points for each feature, followed by a benefit explanation e.g. interchangeable caps is a feature, but what benefits does having these two cap options provide?
- Share different use cases of your products (if applicable)
- Share your opinion and review of a product if it’s a generic product they can buy anywhere
- Overcome objections people may have before purchasing (live chat is great for establishing these)
Ideally, each product should have hundreds of words (or more) helping to close the deal. Not only from a traffic perspective, but in order to convert your visitors into buyers.
If this is their first time visiting your website, having a sentence (or worse, nothing) is unlikely to convert them into a buyer.
Mistake #9: Copied Product Descriptions
Worse than a short description is a copied one. It may seem logical to cover the manufacturers product description, but there’s two reasons why this is a horrible idea:
- It’s rarely written in a way that will convert your visitors
- It’s classed as “duplicate content” from an SEO perspective, so you’ll be trying to rank the exact same content as hundreds or thousands of other eCommerce stores
That doesn’t mean you can’t use parts of it, for example, specifications (i.e. size, weight, material, etc) will always be the same, so feel free to copy them.
But you should also have a custom written product description.
Mistake #10: Missing Product Schema
For the next few mistakes, things will get more technical, starting with Schema.org Markup, specifically for products.
In short, this is a piece of code you can add to your webpage to explain the content to search engines. Sometimes, these details may be shown in the search results, giving a boost in CTR.
Many eCommerce platforms will add this by default now, but our research still found 50.08% of sites did not have it.
If that’s the case for your store, we highly recommend adding it. It’s best practice, and can potentially lead to small ranking improvements.
More importantly, it can lead to massive clickthrough-rate improvements.
By default, there’s a few essential details you’ll want to explain with Schema.org tags/code:
- Product Name
- Price (and currency)
- Availability (is it in stock?)
- Reviews and aggregate rating
The magic comes from the elements shown in the screenshot shown further above:
- Aggregate Rating
- Total number of reviews
If set, all of this information has a chance of being shown in the Google search results, which stands out therefore leading to a sizeable traffic increase.
Unfortunately, our data found only 20% of sites had an Aggregate Rating set, however, this could simply be down to not having any reviews on that specific product page.
The percentage of sites missing Product Schema (50.08%) is a more accurate measure here. Though, considering we picked top-of-category products for our study, it says something about the importance of asking your customers to leave reviews (and then showcasing these on your product pages).

Internal links are where you link from one page to another on your website. You can do this from blog posts, linking to relevant products or categories mentioned.
But there’s also a standard link architecture when building your site.
This type of site architecture is perfect from an SEO perspective because of a few general rules that apply to most eCommerce sites:
- The homepage tends to be the strongest page on the website in terms of backlink authority (i.e. has the most links to it from other websites)
- As a result of this, the more clicks away from the homepage, the weaker a page will be
Within the structure above, product pages can be accessed within 3 clicks. You choose a category, subcategory, and then are presented with products.
(Usually you’ll prioritise best-selling products at the top, so this doesn’t necessarily mean users won’t apply filters or use pagination to click onto the next page of products)
This is also great for user experience – it’s fast and easy.
Mistake #11: Bad Site Architecture
The problem is when this becomes extended, and it suddenly becomes 6 clicks to find a product – even when you know what you’re looking for.
Take an office furniture website I looked at, the site architecture was like this:
Homepage > Office Chairs (Category) > Operator Chairs (Subcategory) > 1 Lever Operator Chairs (Subcategory) > Laval High Back Operator Chair (Product)
This final subcategory should instead be options on the page to narrow down the list, therefore reducing the number of clicks by one.
And that’s a simple problem, some sites had significantly worse structures than this.
For most sites, keep this simple and use the structure from the diagram above. If your store is smaller doesn’t have categories, then just skip that part of the structure.
Mistake #12: No Breadcrumbs
Another internal linking issue is a lack of breadcrumbs. Which, ironically, I’m not using on this website – by choice as the navigation is so simple.
For eCommerce sites though, I recommend adding them for user experience, and also because search engines tend to like them.
These are relatively simple to setup, usually coming default in eCommerce themes. However, there were still 228 sites (19%) not using them in our research.
Another factors that matters equally from an SEO and conversion standpoint is site speed.
A study by Google found the following impact of site loading times on mobile visitors:
- 1-3s loading time increased the bounce rate by 32%
- 1-5s loading time increased the bounce rate by 90%
- 1-6s loading time increased the bounce rate by 106%
- 1-10s loading time increased the bounce rate by 123%
For those unsure, bounce rate is a measurement of the percentage of people that leave a website without browsing more than one page.
Mistake #13: Slow Loading Times
Put simply, the slower your website loads, the less traffic will stay on your website, therefore the lower your sales conversion rate.
From an SEO perspective, the influence of site speed is a commonly debated topic across the industry.
The general consensus is that being lightning fast may not necessarily increase rankings, but having a slow or inconsistent loading website will most definitely damage them.
Aside from real world experience making that clear, it’s also obvious from Google’s perspective. If slow loading sites rank high, people are less happy with the results, therefore less happy with Google.
Our data showed a 3.97 second average loading time according to Google Page Insights.
Is this normal? Well, in a video from the Google Webmaster Team when asked what a “good responsive time” to aim for, they said:
Studies by Akamai claim 2 seconds as the threshold for ecommerce site “acceptability.” Just as an FYI, at Google we aim for under a half-second.
That doesn’t necessarily mean your site needs to be faster than 2 seconds, but it is at least clear that you should aim to have a fast loading site, from both an SEO and conversion point of view.
In our research:
- 72.67% of sites had slower average loading times than 2 seconds
- 55.08% of sites had slower average loading times than 3 seconds
- 22.98% of sites had slower average loading times than 5 seconds
The question then becomes, how do you decrease your site loading time? To answer that, I’ll share a few tips:
1. Use a faster DNS host
Most domain registrars and web-hosts will offer to manage your DNS for you. This is where your nameservers will point (e.g. dns1.registrar-servers.com dns2.registrar-servers.com are the default for NameCheap).
Without getting too technical, the important thing is that every provider has a different level of speed.
By moving to a faster DNS provider like CloudFlare, in some cases, you can speed up your site by upwards of 100ms with very little effort.
2. Use a CDN
A content-delivery network (CDN) is a service that stores copies of irregularly changed files and media (known as Static Content) so they can be loaded quicker, without having to check if there’s been changes every time someone loads the page.
Even better, this Static content will usually be stored on servers closer to the visitors location, so it loads even faster.
(For non-technical readers, if you’re in the UK but visiting a website hosted in the Australia, this will load slower than a website hosted in the UK)
There’s several CDN providers available including CloudFlare, Incapsula, MaxCDN, Amazon CloudFront, and many others.
3. Compress Large Images
If you’re using a decent camera to take photos (you should be), even modern day smartphones, the resolution and file size is likely to be several megabytes.
In other words, these images will take a long time to load, especially on sites with several images (which is best practice).
To avoid this slowing down your website, you’ll want to resize and compress images into smaller file sizes.
For certain platforms like WooCommerce (i.e. WordPress), there’s plugins like Smush that can do this for you. Or a simpler solution is CloudFlare, which will automatically do this on their Pro plan ($20/month).
4. Remove “Code Bloat”
I won’t explain this one too much, but basically, many websites have a lot of wasted scripts and styling loaded for every visitor, that is completely unused, therefore unnecessarily slowing down the website.
This is especially true for usage of purchased themes, even more so, multi-purpose themes that can be used for any number of website types.
If your website is still too slow after all the above tips, consider having a developer look into streamlining your front-end code to see if wasted resources can be eliminated.
An SSL Certificate creates an encrypted connection between the visitor and your website preventing the content being intercepted.
Meaning, it’s essential for eCommerce stores for security more than anything else.
Next, there’s the conversion rate impact.
For online stores especially, your conversions will take a hit when there’s a red “Not Secure” warning above your website.
As for SEO purposes, a study from Brian Dean of a million Google Search results showed a reasonably strong correlation:
HTTPS had a reasonably strong correlation with first page Google rankings. This wasn’t surprising as Google has confirmed HTTPS as a ranking signal.
Though, that study wasn’t comparing types of websites, and for the case of eCommerce sites, I’ll repeat my views that having an SSL certificate (i.e. having your website loading as HTTPS not HTTP) is essential.
Mistake #14: No SSL
Thankfully, it seems most eCommerce sites are aware of this today, as 96.42% of stores we analysed were setup as HTTPS.
Nevertheless, it’s worth mentioning within this guide, as it’s a huge mistake when ignored.
Mistake #15: SSL Errors
A slightly more common issue is errors with the setup. The two most common errors are:
- Certain pages not being set as HTTPS (nor redirected)
- Content being loaded from HTTP
To explain this, we’ll jump back a step first.
Once you have an SSL Certificate, along with the setup process, you’ll have to switch your site from HTTP://example.com to HTTPS://example.com. The S indicates “secure”.
The mistakes come from doing this incorrectly such as:
- Not setting site-wide redirect rules so all HTTP requests are switched to HTTPS
- Not changing links from HTTP to HTTPS (though, this matters less if it’s automatically redirected)
- Not updating file URLs to HTTPs (JS, CSS, Images, etc)
This can cause less severe “Not Secure” warnings, as shown below.
Interestingly, this accounted for 56% of the websites not setup with HTTPS. Which means, they have a valid certificate, they just have issues with their setup.
However, this is still a tiny problem across the whole data set, with only 1.92% of sites (23) suffering from SSL setup errors.
Another type of technical issue is with how the URL structure is setup. This is fairly simple to understand in itself, but can be complicated to setup in practice.
If you’re unfamiliar with the term, it’s simply the template for URLs on various pages of your store. Let’s use Shopify as a popular example.
Shopify Subcategory Pages tend to follow this structure:
Shopify Product Pages tend to follow this structure:
For SEO and user experience purposes, there are general good practices for creating a decent URL structure. In our research, we looked at three mistakes we believe are problematic.
Mistake #16: Too Long
Whether having a URL too long will influence your rankings is up for debate, but we can agree it certainly won’t help.
It also looks messy and ugly to share, from a user experience.
Based on the product pages of all 1,200 stores in our research, 11.58% had URLs longer than 115 characters.
For those stores especially, it’s worth looking into updating their structure or at least problematic pages.
Mistake #17: Repeating Keywords
Repeating keywords in the URL structure is where the same word or words are shown multiple times in a URL.
In the above extreme example, the word “dog” is repeated 3x, “dog food” is repeated 2x, and “food” is repeated 2x. Which is completely unnecessary, the same level of relevance can be achieved with:
Each directory (i.e. /dog/) counts as a level above the previous one, so from this URL, we can determine that the subcategory we’re looking at is about dry food for dogs.
Our study showed 17.92% of sites were repeating keywords in their product URLs.
This won’t directly damage your search rankings, but it puts your webpage at a higher risk of over-optimising for keywords, which will.
Mistake #18: Not Keyword Friendly
The opposite of using too many keywords in your URL structure is not using any.
Some websites have URLs like the following:
Which just about says… nothing.
From both a search engine and user experience, without visiting the page, we can conclusively say we have no idea what it’s about.
By simply including the main keyword in the URL, it makes it clear what the page is about, and gives a massive relevance boost which is helpful from an SEO perspective.
Once again, you do this with templates, for example:
Most of the sites we audited were on top of this, with 74.67% of sites including keywords in their URLs.
Thin or Duplicate Content
For websites with a lot of pages, including many eCommerce sites, thin and duplicate content is a big issue.
Thin content refers to pages with little-to-no unique content on them. Which, as a result, are unlikely to rank in search engines.
Duplicate content refers to pages that are copies of each other directly, or two pages with content on an identical topic aimed at identical keywords. Either way, this causes a conflict.
While not intentional, with many complex eCommerce platforms it can be extremely difficult to set them up correctly to avoid issues like this.
Take this home and furniture store as an example:
For this research, we checked for two types of thin content issues, explained below.
Mistake #19: Pagination Indexed
Each subcategory page is likely to show, maybe, 25 products by default. To see the rest within that category, you’ll need to click onto the next page.
The reason for doing this is loading times, as explained above. Showing too many products at once would take too long to load.
Some sites avoid this with infinite scrolling, which automatically loads up an additional batch of products (i.e. page 2’s products) once you’ve scrolled down to the bottom of page 1’s products.
The problem is when sites have pagination setup and they’re allowed each of the pages to be indexed – this would count as thin content.
These pages are near duplicates of the original subcategory, with identical titles, descriptions, H1’s, etc. Therefore, they should be noindexed.
(By “indexed” I’m referring to being shown in search engines, including when directly searching for the URL)
This can be avoided by using a “noindex, follow” meta robots tag:
<meta name=”robots” content=”noindex, follow” />
Which would be placed on every page past the original subcategory.
Our research found 470 sites (39.17%) were not using noindex tags on their pagination or useless filters (explained below).
Another alternative we found many stores using is a rel=canonical tag, though unless this is pointing to a view-all page (i.e. a page with all products listed on it), this can cause issues with indexing issues with products linked to from the pagination pages.
Mistake #20: Useless Filters Indexed
Similar to indexed pagination issues is indexed filters or options. Often times there’s thin content and/or little value in these pages being ranked in search engines.
Again, I would ensure these are set to noindex.
I’d also take this further and make sure you’re only offering filters that have products, as (correctly) shown in the screenshot above. If there’s no products for a 2 star rating, then don’t show that as an option.
Mistake #21: Duplicate Products
Another issue that stood out in more manual site analysis was duplicate content.
Specifically, duplicate products, usually created in multiple categories such as a special “sale” subcategory along with it’s standard one.
Thankfully, this is easily solved with a “canonical tag”. Let me show you an example…
The above screenshot is an example of duplicate content (done right), they have two identical products, yet they’ve removed the issue with a tiny line of code.
If you have duplicate content and it’s necessary, then make sure you’re using a canonical tag to tell search engines which page to index. Unlike the store above, not every site is doing this.
Mistake #22: Outdated Subcategories
For bigger stores with a lot of products and categories, one simple mistake to run into is having thin (arguably, duplicate) content pages showing zero products.
Our research was mostly only on the 3 types of pages explained at the beginning of this guide, but this was something we noticed when manually looking through a few of the bigger sites.
The same would also happen if you’re linking to empty filters, and worse, not setting them as noindex.
In the above example from Walter Drake, the best solution would be to remove the pages and 301 redirect (permanent redirect) to a closely related page, which I’m sure they have.
Now that we’ve covered all the mistakes, I want to address the point of data accuracy before wrapping up this article.
This data was collected from a mix of automated (scraped) and manual effort from myself and three assistants.
While we’ve done our best to ensure the accuracy of this research, there’s 4 potential issues with it:
- We conducted our research by looking for specific issues based on our industry experience, rather than mass-analysing the sites and listing the issues based on the data.
The latter could have possibly revealed mistakes we may have overlooked.
- We only analysed the homepage, one category page (if applicable), one subcategory page, and one product page.
This can skew the data if we happened to pick a page that generates few sales or traffic, since the website owners will likely put less effort into those pages.
- There’s possible there could have been some mistakes where our scraper had minor issues or simply from manual research.
I don’t have specific mistakes to point at, but when analysing a lot of data and combining it with manual work, it’s likely to expect some minor mistakes.
- Not everyone cares about SEO nor is every page intended to be ranked
Some of the pages and/or sites analysed were clearly not intended to rank in search engines, which explains why they had few or bad onpage factors.
Though, that doesn’t mean they couldn’t benefit from making the changes suggested here.
Overall though, the data serves as a fun way of ranking and comparing the popularity of different mistakes. Here’s the list of mistakes in order of commonality:
|Not using modifiers in title tags||91.08|
|Meta description not optimised for CTR||76.17|
|Loading time slower than 3 seconds||55.04|
|Not using product schema||50.08|
|No description on subcategory page||41.75|
|Pagination or useless filters indexed||39.17|
|No description on category page||37.35|
|No description on product page||29.34|
|URLs not optimised for keywords||25.34|
|Meta description not set correctly||24.25|
|Loading time slower than 5 seconds||22.98|
|Not using breadcrumbs||19|
|Repeating keywords in URL||17.92|
|Repeating keywords in title tag||16.84|
|URL longer than 115 characters||11.58|
|Not using HTTPS||3.58|
|SSL Setup Errors||1.92|
Note: These are ordered by commonality of the mistake, not based on importance. SSL setup errors ranked as the least common, thankfully, but irregardless of SEO it’s extremely important for any website to resolve – especially eCommerce.
While some mistakes suggested here are less important than others, only 3 out of 1,200 sites (0.25%) completely passed all our requirements.
That doesn’t mean the other stores aren’t ranking well, it simply means there’s improvements that could get better results – at least for certain pages.
