Keyword cannibalization: when your own pages compete

Spot a tie before you merge anything

Open the queries where two of your URLs swap places from week to week. If both pages promise the same decision to the same reader, you do not have a topic cluster. You have a tie that search has to break without your help.

Compare titles, H1s, and the opening paragraph. Cannibalization usually starts there. A shared brand mention in a footer is not the same problem as two service pages written for one query.

• Export the query and look for multiple ranking URLs.
• Read both pages as if you had to pick one next step.
• Ignore overlap that is only a shared navigation label.

Give one URL the query

Keep the page with the clearer intent match, stronger internal links, and more useful answer. If the other URL has no distinct job, redirect it. If it can serve a narrower question, rewrite the title, H1, and opening so the query sets separate.

Then fix the anchors. Five internal links using the same phrase for both URLs will keep the mixed signal alive after the copy change.

Measure ownership, not a one-week traffic dip

In Search Console, watch impressions for the contested queries and how many of your URLs still receive clicks for them. The useful outcome is one URL owning the query.

A short combined-click dip can happen while the surviving page settles. Judge the change after the redirect or rewrite has been recrawled, not the afternoon you publish it.

Is keyword cannibalization a Google penalty?

No. It is overlap. Search has several of your URLs to choose from for one intent, so the stronger single page often underperforms until you assign a clear owner.

Should overlapping pages always be redirected?

Redirect only when the weaker page has no separate reader job. If it can answer a narrower question, rewrite it instead of collapsing it.
