How To Identify & Eliminate Keyword Cannibalization To Boost Your SEO

Do you have multiple pages on your website ranking for the same keyword?

That may sound like a good thing.

After all, the more pages you have in search results, the more impressions you will receive from search users, right?

Unfortunately, that isn’t always the case.

Targeting a specific term across multiple pages can have the opposite effect. You may do more harm than good to your SEO for that keyword.

The reason is simple — when you have multiple pages ranking for the same keyword, you force your pages to compete with each other.

Consequently, each page has a lower CTR, diminished authority, and lower conversion rates than one consolidated page would have.

We call this SEO misstep keyword cannibalization.

What Is Keyword Cannibalization?

Keyword cannibalization is known as such because you’re “cannibalizing” your own results by splitting CTR, links, content, and (often) conversions between two pages that should be one.

When you do this, you aren’t showing Google the breadth or depth of your knowledge. You aren’t improving the authority of your site for that query, either.

Instead, you’re asking Google to weigh your pages against one another and choose which ones it thinks suits the matching keywords best.

For example, let’s say that your website sells shoes, and [shoes] is the only keyword you target. You’re essentially telling Google that every page is about shoes regardless of whether they’re hiking shoes, tennis shoes, sneakers, etc.

Instead of capitalizing on a lot of valuable longer-tail keywords such as women’s shoes, running shoes, etc., you’re competing against yourself for one keyword that may be too broad to have commercial intent.

6 Negative Effects Keyword Cannibalization Can Have On Your SEO

Keyword cannibalization can have disastrous consequences for your SEO. Many people suffering from keyword cannibalization aren’t even aware there’s an issue.

They might even be happy that one page is ranking in the fifth and sixth slot for their targeted keyword, without realizing that one authoritative page would probably rank higher and convert better.

The practical consequences are clear. However, lost site traffic, queries leading to the wrong page, fluctuating SERP rankings, and ultimately lost sales may also result, and are more difficult to detect.

Why?

Because…

You’re Diminishing The Authority Of Your Page

Instead of having one highly authoritative page, you’re splitting your CTR among multiple moderately-relevant pages.

Essentially, you’ve turned your pages into competitors and now you’re fighting for pageviews and SERP rankings.

Consider it from the point of view of a reader looking for a new book on Amazon. Would you rather have one, in-depth book about a topic that demonstrated your expertise?

Or would you prefer to have two or more less complete books about a topic, each leaving you wishing there was more information?

You’re Diluting Your Links & Anchor Text

Backlinks that could have gone to one consolidated source of information are now being split between two (or more) pages.

The outreach efforts spent on acquiring 10 links for one page and 15 links for another could have been spent acquiring 25 links for one better-performing page.

Furthermore, a complete, in-depth page is more likely to be linked to than lighter, less comprehensive pieces.

Similarly, your anchor text and internal links are leading visitors to multiple different pages instead of one authoritative page on the subject.

Google May Devalue The More Relevant Page

Keywords are one of the main ways in which we help Google understand what our pages are about.

If all of your keywords are the same, Google tries to understand which page is the best fit – and if your content is too similar, it might get it wrong.

For example, let’s say you have two pages ranking for the same keyword. If the higher converting page ranks lower, you could be missing out on high-value, converting traffic.

You’re Squandering Crawl Budget

Your crawl budget is the number of times a search engine spider crawls your website in a given time period.

Having multiple pages devoted to the same keyword results in the crawling and indexing of pages that aren’t needed.

Note: Small sites probably won’t notice a difference or ever have to worry about their crawl budget, but large ecommerce sites or vendors with multiple products may.

It’s A Sign of Poor Page Quality

Multiple pages targeting the same keyword tells your users that your content is probably stretched thin. It also signals to Google that your content may not match your keywords on each page.

Your Conversion Rate Will Suffer

Inevitably, one of your pages will convert better than the rest.

Instead of directing new visitors to that page and making it the most authoritative page possible, you’re instead losing potential leads when they land on less relevant pages.

How To Identify Keyword Cannibalization

Fortunately, once you’ve identified the problem, fixing keyword cannibalization is easy.

Identifying keyword cannibalization is as easy as creating a keyword matrix.

Simply create a spreadsheet that lists all of your site’s important URLs and their associated keywords.

For example, if your site sells shoes, then your spreadsheet might look like this:

Alternatively, you can use a keyword mapping tool, which might look like this:

Once you’ve listed your URLs and their keywords, run down the list and look for any duplicate entries.

If you spot any – especially across core pages – you’re probably suffering from keyword cannibalization.

Now it’s time to fix those pages!

Note that keyword cannibalization can even occur if the meta information in your title tags seems to target the same keyword, so double-check those, too.

If you’re using a rank tracking tool, you may also want to take this opportunity to search for thin content and keywords mistakenly applied to the wrong page.

It’s a good time to give your site a little TLC.

How To Fix Keyword Cannibalization

How you solve keyword cannibalization depends on the root of the problem.

More often than not, the issue is simply one of organization. But particularly stubborn cases may require that you break out the 301s or new landing pages.

Here are five possible solutions.

1. Restructure Your Website

The simplest solution is often to take your most authoritative page and turn it into a landing page, which links to other unique variations that fall under the umbrella of your targeted keywords.

If we return to our shoe-product example, it might make sense to make “shoes” our canonical source page and link all more specific variations back to it.

2. Create New Landing Pages

Alternatively, you might lack a landing page that consolidates all of your product pages in one place.

In this case, you’d benefit from creating a unique landing page to serve as your authoritative source page and link to all of your variations from there.

In our example, we might create a page called “hiking shoes” and another called “sneakers for men.”

These should allow you to target both broad keyword terms with your consolidated pages and long-tail keywords on your variations.

3. Consolidate Your Content

If your pages aren’t unique enough to warrant having multiple pages targeting the same keyword, consider combining them into one page.

This is a chance to take two underperforming pages and turn them into a more authoritative source. It may also solve thin content issues.

Start with your analytics to determine which page performs best in terms of traffic, bounce rate, time on page, conversions, etc. You may find that one page receives most of the traffic, but the other has the content that converts more users.

The goal, in this case, could be to consolidate the converting copy content on the page with the most traffic. Ideally, you would be able to maintain the same ranking and convert more of the traffic.

An added benefit of this approach is that you won’t have to worry about having your website penalized for content that Google considers thin or cookie-cutter-like.

4. Find New Keywords

Finally, if you’re already blessed with highly diverse, content-rich pages, and the only thing your website is suffering from is a poorly planned keyword strategy, maybe all you need to do is find new keywords.

Just make sure your keywords accurately describe your page’s content. Will a website visitor who searched for the target keyword be satisfied by the content on each page that ranks for it?

If the answer is no, it may be time to do some keyword research.

Looking at your pages in a spreadsheet with the following details can help you spot better keyword opportunities for similar pages:

  • Keyword & rank.
  • The page URL.
  • SEO title & meta description.
  • Word count.
  • Organic traffic.
  • Bounce rate.
  • Conversions.

This should help you spot pages targeting the same keywords.

From there, you can determine which pages are most valuable, which can be consolidated, and which need new keywords.

In most cases, you can use your keyword research tool to find the most relevant keywords for all of the pages you want to keep.

If you have two pages ranking well for a long-tail keyword, see if there is a related broad term you could be focusing on for one of them to capture more traffic.

Once you find that keyword, reoptimize for it accordingly and update the details in your spreadsheet for future reference and performance tracking.

5. Use 301 Redirects

While I generally advise against using too many 301 redirects (see my list of the 10 Most Harmful Mobile SEO Mistakes), they might be necessary if you already have multiple pages ranking for the same terms.

Using 301s allows you to consolidate your cannibalized content by linking the less relevant pages to a single, more authoritative version.

Keepin mind though that this tactic is suitable only for pages with similar content and those matching specific keyword queries.

Conclusion

These five solutions will fix most cases of keyword cannibalization. Still, if you manage an ecommerce website, you should be particularly careful to note how your CMS separates products with variable sizes and colors.

Some CMS programs create separate pages for every product variation.

If your CMS is organizing products like this, you should either restrict duplicate pages from being indexed using robots.txt or <meta name=”robots” content=”noindex”> tags, or you should use canonical URLs to consolidate link signals for the duplicate content.

Keyword cannibalization is more prevalent today than ever before.

Ironically, its victims are usually webmasters who recognize the importance of SEO for their business. Yet while they intend to optimize their site, they don’t fully understand how to ‘speak’ Google’s language.

Fortunately, if your website is cannibalizing its target keywords, solutions aren’t hard to come by — and the damage isn’t permanent.

With the right tools and a “can-do” attitude, you can give your SEO a well-deserved boost.
