Free Keyword Cannibalization Checker
Enter 2–10 URLs and a target keyword to detect overlap, content similarity, and self-competition in search results.
Free Keyword Cannibalization Checker
When multiple pages compete for the same keyword, Google cannot determine which to rank — so it ranks none of them well. Our free tool computes pairwise content similarity and keyword density across up to 10 URLs so you can consolidate, differentiate, or canonicalize your way out of self-competition.
How Keyword Cannibalization Destroys Rankings
Split Link Equity
Backlinks pointing to Page A for a keyword and backlinks pointing to Page B for the same keyword split the total authority you've built. Neither page accumulates enough to rank as well as a single consolidated resource would.
Google's Indecision
When Google crawls two near-identical pages targeting the same intent, it must decide which to rank. It often oscillates between them — swapping rankings week to week — causing unpredictable performance and click-through instability.
CTR Dilution
If two of your pages appear for the same query, the combined click-through rate may be lower than a single dominant listing because users see repeated brand results and perceive a lack of variety in the search results.
What to Do When Cannibalization is Detected
The first step is establishing which page has more authority — check backlink counts, internal link counts, and historical ranking performance. The weaker page should either be merged into the dominant page (with a 301 redirect), given a clearly distinct subtopic and keyword focus, or canonicalized to the dominant page if the content is truly duplicative. Consolidation consistently produces ranking lifts for the surviving page within 4 to 8 weeks as Google processes the structural change.
After resolving cannibalization, use our Free Thin Content Detector to verify the surviving page meets content quality thresholds, and our Free Internal Link Audit to redistribute internal link equity appropriately.
