Keyword cannibalization
When two of your own pages compete for the same keyword, splitting rankings so neither one wins.
In depth
What it really means
Keyword cannibalization happens when multiple pages on your site target the same keyword and intent. Instead of one strong page, you have two or three weaker ones splitting the clicks, links and authority, and Google isn’t sure which to rank.
It is a common side effect of publishing over time without a plan. The fix is usually to consolidate, not to create yet another page.
Example
You publish an email deliverability guide in 2022, then another in 2024 targeting the same query. Now both hover on page two, each undermining the other, when one merged, updated page could rank on page one.
Best practices
- Map keywords to a single target page each, before writing.
- Audit for overlaps: search your site for the keyword and see how many pages compete.
- Merge competing pages into one stronger page, then redirect the rest.
- Differentiate intent if both pages should exist.
- Use internal links to point the keyword’s anchor at the chosen page.
- Re-check after big publishing pushes.
FAQs
How do I know if I have cannibalization?
Search your keyword with a site filter, or check Search Console for a query where several of your URLs trade positions. Multiple competing pages is the tell.
How do I fix it?
Usually consolidate: merge the competing pages into one, redirect the others, and point internal links at the winner.
Is cannibalization always bad?
If pages target genuinely different intents, they can coexist. It is only a problem when they chase the same query and split performance.
Does more content cause it?
Publishing without a keyword map does. Volume is fine as long as each page owns a distinct keyword and intent.
Can internal links cause cannibalization?
Inconsistent anchor text pointing at different pages for the same term can confuse signals. Keep the anchor pointing at your chosen page.
