Keyword Cannibalization: What It Is (and How to Fix It on PrestaShop)

You have several well-written pages on the same topic, yet none of them really ranks? You're probably a victim of keyword cannibalization — an invisible but very common problem on PrestaShop stores with dense catalogs.

AEO definition: what is keyword cannibalization?

Keyword cannibalization happens when several pages on the same site target the same query with the same intent. Instead of reinforcing each other, these pages compete: Google doesn't know which to favor, dilutes the signals (links, clicks, authority) between them, and ends up ranking each one worse than a single consolidated page would.

Why it's a problem

• Diluted signals: your backlinks and clicks spread across multiple URLs instead of one.
• Unstable rankings: Google alternates between the pages, consolidating none.
• Lower CTR: no page becomes "the" clear reference.
• Wasted crawl budget on redundant pages.

Typical cases on PrestaShop

1. A category and a flagship product both targeting the same generic term.
2. Several product variants (color, size) indexed separately on the same keyword.
3. A blog post and a product page targeting the same transactional query.
4. Faceted filters generating dozens of near-identical URLs.

How to detect it in Search Console

1. Open the Performance report.
2. Click an important query → Pages tab.
3. If several URLs receive impressions for the same query, you have cannibalization.
4. Also watch for queries whose position swings a lot over time: a classic sign.

4 ways to fix it

1. Consolidate

Merge redundant pages into a single, more complete reference page, and 301-redirect the others.

2. Differentiate the intent

Keep both pages but re-target them: one for the informational intent, the other for the transactional one. Rewrite titles, meta and content accordingly — see Write title & meta tags.

3. Canonicalize

For variants and faceted filters, use the canonical tag to point to the main page.

4. Internal linking

Point your internal links (with a consistent anchor) to the page you want to rank. See Understand internal linking.

Automate detection

Spotting cannibalization by hand across hundreds of products is tedious. Fexa AI cross-references your Search Console data with your catalog and automatically flags the pages that cannibalize each other, with the list of competing URLs — so you handle the real cases directly.

In summary

Cannibalization is several pages fighting over the same keyword and weakening each other. Detect it via Search Console (multiple URLs on one query), then consolidate, differentiate, canonicalize or re-link. To go further, read the complete PrestaShop SEO guide.
