How to Identify and Fix SEO Cannibalization

SEO cannibalization is when two or more pages on your website target the same keywords and compete against each other in Google results. The result: neither page ranks properly. Sandro, cofounder of Gemeos Webflow agency, shows you how to spot it and fix it.

Why cannibalization is a problem

When Google finds two similar pages on your site, it doesn’t know which one to prioritize. It may switch between them from one day to the next, or even pick the less relevant one. The authority that could strengthen one strong page gets split across several weak ones.

• Unstable rankings that are hard to improve
• Internal PageRank spread across multiple URLs
• Lower click-through rate if Google shows the wrong page
• Harder to push one specific target page up the rankings

1. Spot cannibalization with Search Console

In Search Console, go to "Performance" > "Queries". Type a target keyword into the "Query contains" filter. Click the "Pages" tab: if several URLs appear for that keyword, you may have cannibalization.

Repeat the process for your 10 to 20 most strategic keywords.

2. Spot cannibalization with Screaming Frog

Once the crawl is done, export all pages ("Internal" tab > "Export"). In a spreadsheet, review the Title Tags and H1s: pages with very similar titles on related topics are suspicious. Also compare the meta descriptions.

3. Pick the "winning" page

For each group of cannibalized pages, choose one main page. Criteria: the one with the most inbound backlinks, the best ranking history, the most complete content, and the cleanest URL.

4. Apply the right fix

Depending on the case, several solutions are available:

• 301 redirect: if the secondary page adds no value, redirect it to the main page. The most radical solution, but also the most effective
• Canonical tag: if the secondary page needs to stay accessible (for UX or navigation) but shouldn’t be indexed, add a canonical tag pointing to the main page
• Content merge: combine the two pages into one more complete page, then redirect the old one to the new one
• Intent differentiation: if the two pages actually target different search intents, refocus each one on its own intent

5. Check the result in Search Console

After the fix, submit the affected URLs in Search Console via "URL Inspection" > "Request indexing". Wait 2 to 4 weeks and check that the main page is consolidating its rankings.

Conclusion

SEO cannibalization is often silent: sites build it up naturally by publishing content without a clear map first. A quarterly audit is enough to keep it under control.

• Use case 1: a blog with several articles on similar topics written at different times
• Use case 2: an e-commerce site with category pages and tag pages cannibalizing each other
• Use case 3: an agency site with service pages that are too similar (e.g. "SEO" and "organic search optimization")
