Keyword Cannibalization Checker

Find out if multiple pages on your site are competing for the same keyword.

What this tool does

The Keyword Cannibalization Checker searches the top ~100 results for your keyword and finds every page from your domain that appears. One ranking page is healthy. Two or more means you may have a cannibalization problem: your own pages competing against each other, splitting relevance signals, internal links, and backlinks that should be consolidating into one strong result.

Cannibalization is the silent tax on growing content sites. It creeps in naturally — you write about a topic in 2024, again from a slightly different angle in 2025, and Google ends up alternating between two middling pages instead of ranking one great one. The classic symptoms: rankings that flip-flop between URLs week to week, a page that won't budge past position 8 while a sibling page hovers at 20, and impressions split across two URLs in Search Console.

If the checker finds multiple pages, the standard fixes are to merge them into one definitive article with a 301 redirect, differentiate them to target genuinely distinct intents, or de-optimize the weaker page. Run the check on every keyword that matters before you publish something new against it — and SirWritesALot runs this same check inside every article project.
