Keyword cannibalization happens when two or more pages on the same website target the same keyword or search intent, so instead of one strong page ranking well, several weaker ones compete against each other for the same spot. Google can only show one of your pages per search result in most cases, and it doesn't always pick the one you'd have chosen - sometimes an older, thinner page outranks the newer, better one you actually wanted to send traffic to.
It's an easy problem to create by accident. Most small business sites end up with cannibalization not through carelessness, but through normal growth: a blog post written months ago quietly targets the same term as a service page added later, and nobody notices because both pages still get some traffic.
How to Tell If You Have It
- Search Google for
site:yourdomain.com "your target keyword"- if multiple pages come back for a term you only meant to target once, that's your first signal. - Check Google Search Console's Performance report, filtered to the keyword in question. If impressions are split across two or more URLs with unstable, swapping positions from week to week - one ranks position 8 one week, a different page ranks position 11 the next - that instability is a classic cannibalization symptom.
- Compare your page titles and H1s. If two pages could plausibly answer the exact same search query, they're candidates even before you check rankings.
Common Causes on Small Business Sites
- A blog post and a service page chasing the same term - a post titled "What Is [Service]?" and the service page itself both trying to rank for the same core keyword, when the post should target the informational version of the query and the service page the commercial one.
- Location pages with too little differentiation - near-identical pages for different towns or branches, all effectively targeting the same "[service] near me" intent with barely different content.
- Old content nobody revisited - a post from a year ago still ranks, unnoticed, for the same term a newer, better page was built to target.
- Category and tag pages competing with a cornerstone post - especially common on WordPress sites where tag archive pages get indexed by default and end up thin-but-competing versions of a topic a dedicated article already covers properly.
How to Fix It
- Decide which page should win. Usually the one with more existing authority (backlinks, age, current rankings), the strongest content, or the one that best matches the searcher's actual intent.
- Differentiate what's left. If both pages genuinely deserve to exist, retarget the weaker one at a more specific, related keyword rather than the same head term - an informational post and a commercial service page can coexist if they're clearly aimed at different stages of the same search journey.
- Consolidate if they can't be differentiated. Merge the useful content from the weaker page into the stronger one, then either delete the weaker page with a 301 redirect to the survivor, or noindex it if you need to keep it live for other reasons.
- Update internal links pointing at the removed or demoted page so they all point to the one you want to win - see our internal linking guide for how to do this without breaking anything.
The Fast Way to Check Yours
Spotting cannibalization by hand means cross-referencing every page's target keyword against every other page's - tedious on a site of any real size.
