Keyword cannibalization: SEO’s biggest challenge

Key takeaways

  • Content cannibalization hurts SEO rankings when multiple pages target the same keywords.
  • Some keyword overlap between pages is normal. Complete duplication is the problem.
  • Innovative approaches like the topical authority model can help manage keyword overlaps.
  • A well-planned content strategy and merging or adjusting content can prevent cannibalization.
  • Emerging AI solutions map content topics more holistically to identify duplication.

Creating multiple pages and content on the same topic may seem like a good idea when building a website or blog. More content means more opportunities for users to find you, right?

Unfortunately, it's not that simple. Too much content targeting the same keywords can lead to keyword or content cannibalization, which can hurt your search engine rankings.

Let's uncover what content cannibalization is, how best to avoid it, and software solutions for building a content strategy that works for you.



Understanding keyword cannibalization

While it is sometimes difficult to detect, content cannibalization occurs when search engines encounter overlapping content. This creates confusion and impacts the overall effectiveness of a website's SEO strategy.

The overlap of keywords is almost inevitable because websites typically rank for thousands of them, many of which are similar. Therefore, on any website, multiple pages often end up sharing keywords, especially large websites with lots of content.

Different sections can rank for different keywords

Usually, the main keywords a page targets are those included in the H1 or title of the page, so it's crucial not to have two pages with titles targeting the same keywords.

For example:

Having one page titled "Is keyword cannibalization good for SEO?" and another titled "Is keyword cannibalization bad for SEO?" isn't ideal. These two pages are competing and may confuse both search engines and users.

However, you might discuss keyword cannibalization when structuring content and touch on related topics like content creation or blog writing. These could be topics covered in other articles, but your post may still rank for them. Even if you only mention them briefly, these topics can affect the range of keywords that your page ranks for.

Keep in mind:

Not every instance of multiple pages ranking for the same keyword counts as cannibalization. Sometimes, this overlap might be acceptable or even necessary to establish topical authority.

Although we often refer to this problem as keyword cannibalization, it's unclear whether Google uses the same term. That said, Google recognizes and responds to duplicate content. If a website contains multiple posts targeting the same keywords, Google might see this as duplicate content and decide not to index these pages.

Alternatively, Google might index them but divide the traffic between them, diluting their potential reach, or prefer one page over the other and exclusively direct traffic there.

Tools and techniques to identify keyword cannibalization

Despite the pressing need for a solution to keyword cannibalization, there are no straightforward tools to tackle this issue effectively. SEO professionals often use a manual approach that involves examining each page and comparing keywords through tools like Google Search Console.

However, doing things manually can become almost impossible, especially with a lot of social media content.

One innovative approach is the topical authority model. Rather than focusing on individual keywords, this method centers on broader topics, encompassing multiple keywords with similar intent. By mapping the relationship between these topics and various pages, SEOs can determine when pages compete or complement each other.

By combining complete topic mapping with head-to-head keyword overlap alerts, Entail AI provides the insights you need to streamline your entire content creation process for the best user journey.



Preventing and fixing cannibalization

Preventing both content and, specifically, keyword cannibalization begins with a well-thought-out content plan. Once you identify keyword cannibalization, steps to resolve it include:

  • Merging competing pages
  • Deleting redundant pages
  • Optimizing existing pages instead of creating duplicates
  • Adjusting the content to target different keywords

These steps will eliminate competition between pages on your website and improve your site's SEO performance. Fewer pages mean less of a cannibalization risk. For example, updating a forecast page daily rather than creating new pages for each forecast reduces the risk of cannibalization.
