Keyword Cannibalization

Why it matters: cannibalization quietly caps your ceiling. Google generally shows only one or two URLs per site for a given query, so when two of your pages compete, they split clicks, backlinks, and internal-link equity that should stack on a single page. The symptom is a keyword that flip-flops between URLs week to week in Google Search Console, or two pages that each hover on page two instead of one page that ranks. It is especially common after a site has been publishing for a year or two and topics start to overlap.

How to diagnose it: in Search Console, open Performance, filter by the exact query, then check the Pages tab. If impressions for that query are spread across two or more URLs, you likely have cannibalization. Confirm with a site search (site:yourdomain.com “target keyword”) to see every competing page. The fix is one of three moves: consolidate (301-redirect the weaker page into the stronger one and merge the content), differentiate (re-target one page to a distinct intent, such as turning a duplicate “teeth whitening” page into “teeth whitening cost”), or canonicalize (use rel=canonical when both pages must exist). Common mistakes: deleting a page without redirecting it, and treating an informational blog post and a commercial service page as competitors when they actually serve different intents and can both rank.

How it connects to local SEO and AEO: for a Central Florida small business, your money pages are usually “[service] + [city]” , one clean, authoritative page per service per location. Cannibalization dilutes exactly those pages, which also weakens local pack signals. For answer-engine optimization, it matters even more: AI assistants like ChatGPT, Perplexity, and Google’s AI Overviews tend to cite a single best source, so two half-strong pages give them nothing decisive to quote, while one consolidated page with a clear answer, FAQ schema, and consistent NAP gives them an obvious citation target.
