Keyword cannibalization is something that can happen to any website, no matter the size or amount of content.
It can be an issue because it can negatively influence your search engine positions.
In this blog post, we’ll discuss what is keyword cannibalization, how it may impact your rankings, and how to identify and fix it!

What Is Keyword Cannibalization?
This can happen unintentionally if you have similar pages or if you use the same keyword multiple times on different pages.
It can hurt your website because it confuses search engines. They don’t know which page to rank for the keyword, so they may not rank any of them.
For example, let’s say you have two pages about “link building“.
If you use the keyword “link building” on both pages, then you’re keyword cannibalizing.
This can be an issue because it can impact each page’s ability to rank well in search engines.
Keyword cannibalization can also happen on a smaller scale.
For example, you may have a page about “link building” and another page about “link building strategies“.
If you use the keyword “link building” on both pages, then you’re probably keyword cannibalizing.
How Keyword Cannibalization Impacts Your SEO
Keyword cannibalization is bad, but it’s important to point out that you have a real issue only when you have several pages targeting the same keyword.
Considering that pages can rank for many keywords, it may not be the case.
In fact, according to a study by Ahrefs, pages that rank in the top 10 for one keyword typically rank for hundreds of other keywords:
For example, let’s say that you have two pages created around the keyword “on-page SEO“.
One of them ranks in the top positions, while the other one is not. You could blame keyword cannibalization because the first page is stealing organic traffic from the second one.
Now, even if it’s true that you are not getting traffic for that specific keyword, both pages can rank for hundreds of other keywords!
And if you could decide to combine the two pages into a big one, you could potentially lose some of the keywords you were previously ranking for (and see a drop in organic traffic).
In general, keyword cannibalization can impact your website’s SEO in a few different ways:
- It can split up your link equity: If you have multiple pages that are keyword cannibalizing, then the link equity (i.e. the power of your links) will be split between those pages instead of going to just one page.
- It can dilute your keyword rankings: If you’re keyword cannibalizing, then it’s likely that only one of your pages will rank for that keyword. The other page(s) will struggle to rank because they’re competing with a similar page on your site.
- It can confuse search engines: If you have multiple pages that are keyword cannibalizing, then it can be difficult for search engines to understand which page is most relevant for that keyword. This can impact your rankings and click-through rates.
Keyword Cannibalization Examples
Here are some of the most common keyword cannibalization issues:
- URLs That Keep Changing Rankings
- Ranking Keywords Fail to Increase
- URL That You Don’t Want Are Ranking
URLs That Keep Changing Rankings
You may have keyword cannibalization if your URLs keep changing rankings.
This happens when Google cannot figure out which URL should rank for a keyword.
This can be an issue because it can make your website appear unstable to Google and may impact user experience, including your click-through rates.
Two years ago Google’s John Mueller made an AMA on Reddit and someone asked about keyword cannibalization:
And the final comment was:
Write for your audience, how they would search, and how they digest content. There’s no word-count necessary, no keyword density needed.
Ranking Keywords Fail to Increase
You may have keyword cannibalization if your ranking keywords fail to increase.
This happens when you have multiple pages that are keyword cannibalizing and the authority of the pages are splitting the link equity.
As a result, your keyword rankings stay the same or may even drop.
URL That You Don’t Want Are Ranking
It may happen that you will find out that the wrong URL ranks for a certain keyword.
For example, a product ranks for a keyword that you want your category page to rank for.
This happens when you have keyword cannibalization and search engines are confused about which page is most relevant for that keyword.
How to Identify Keyword Cannibalization
To identify it, you need to understand what the searcher is looking for and match it with the right content.
If multiple pages are targeting the same keywords but NOT the same intent, then it’s not a keyword cannibalization issue.
But when the intent is the same for certain pages, then you are basically competing against yourself.
Here are some free ways to find these pages:
- Site: Search Operator
- Google Search Console
Site: Search Operator
One of the easiest ways to find keyword cannibalization issues is to use the “site:” search operator.
Just type in “site:[yourdomain.com]+keyword” into Google and it will show you all the pages from your website that are ranking for that keyword.
From there, you can analyze the pages to see if they are keyword cannibalizing.
For example, if we type:
We can see that Moz.com has actually cannibalization issues.
Google Search Console
Another way to find keyword cannibalization issues is to use Google Search Console.
Just go to the “Performance Report” > “Pages”.
Here, you can see which pages are ranking for the same term, by clicking on each of the keywords your website is ranking for.
Ahrefs is a paid keyword research tool that also has a feature to find keyword cannibalization issues.
Just go to “Site Explorer” > “Organic Keywords” and toggle “Multiple URLs only”
Ahrefs will show you all the pages that are ranking for the same keyword.
For example, let’s run a search for Moz.com:
As you can see, Site Explorer found the same issue for the term “keyword cannibalization” as it was identified earlier using method #1.
How to Fix Keyword Cannibalization
Here are some of the most common ways to fix the problem:
- Noindex Tags
- Canonical Tags
This is the most common and used practice to solve the issue.
Basically, you want to take all the keyword cannibalizing pages and combine them into one single page.
For example, if you have two pages that are keyword cannibalizing, you want to take the content from both pages and put it into one.
You can then redirect the other page to the one that you want to rank.
Doing this will help Google understand which page is most relevant for the keyword and should be ranked.
One way to fix keyword cannibalization is to use “noindex” tags.
The noindex tag tells Google not to index a page.
This is useful if you have pages that are keyword cannibalizing but you don’t want them to rank.
All you need to do is add a meta robots noindex tag to those pages and Google will stop indexing them.
Another way to fix keyword cannibalization is by using redirects.
Redirects are used to send users from one URL to another.
This is useful if you have pages that are keyword cannibalizing but you want to redirect the traffic to another page.
For example, you may want to redirect a product page to your category page.
All you need to do is add a 301 redirect from the old URL to the new URL and Google will start sending traffic from the old URL to the new one.
A canonical tag is an HTML tag that tells Google which version of a webpage is the original.
This is useful if you have pages that are keyword cannibalizing but you want Google to index only one of them.
All you need to do is add a canonical tag to the pages that you want Google to index and Google will start indexing only those pages.
Keyword cannibalization can hurt your SEO.
It’s important to find and fix these issues so that you can avoid any ranking problems.
