Detect keyword cannibalization by pasting multiple page titles, meta descriptions, or content snippets. Finds overlapping keyword clusters, scores similarity between pages, identifies which pages compete for the same terms, and suggests canonical or consolidation fixes.
Paste the title, URL, and optionally the meta description or first paragraph of each page you want to check. Enter one page per section — the tool supports up to 20 pages. You can also paste a list of URLs and titles from a spreadsheet.
The tool extracts significant keywords from each page (filtering stop words), builds a keyword-to-URL map, and calculates a keyword overlap score between every pair of pages. Pages sharing more than 30% of their significant keywords are flagged as potential cannibalization candidates.
A conflict matrix shows which page pairs overlap and by how much. For each conflict, the tool suggests a fix: canonical tag (point duplicate to original), 301 redirect (if one page is significantly weaker), content differentiation (if both serve different intent), or merge (if both pages cover the same topic at similar depth).
Keyword cannibalization occurs when multiple pages on your website compete for the same target keyword in search results. Instead of one strong page dominating a SERP position, two or more weaker pages split rankings, clicks, and link equity between them. Google is forced to choose which page to show, often cycling between them unpredictably. Signs include: pages swapping in and out of rankings for the same query, neither page reaching its potential ranking, traffic that should be concentrated on one page spread thinly across several.
Not always. Some "cannibalization" is intentional and beneficial. An e-commerce site might have both a category page and multiple product pages ranking for related terms — that is normal coverage, not cannibalization. Cannibalization becomes a genuine problem only when multiple pages target the same user intent with similar content depth. The key test is search intent: if two pages both target the same query with the same answer for the same type of user, that is problematic. If one targets informational intent and another targets transactional intent for the same keyword, that is acceptable diversification.
There are four main fixes depending on the situation. (1) Canonical tags: if you need to keep both pages but want one to rank, add rel="canonical" on the weaker page pointing to the stronger one. (2) 301 redirect: if one page is clearly inferior or redundant, redirect it permanently to the stronger page. (3) Content differentiation: rewrite both pages to target different angles, user intents, or sub-topics of the keyword. (4) Merge and redirect: combine both pages' best content into one comprehensive page and 301 redirect the weaker URL to the merged page.
This tool uses text similarity analysis on the page titles, meta descriptions, and content snippets you provide. It extracts significant keywords (after removing stop words), builds a keyword frequency map for each page, and calculates the Jaccard similarity coefficient between every pair of pages. A similarity score above 30% indicates meaningful keyword overlap. While this is less definitive than GSC data (which shows actual ranking overlap), it is useful for proactively auditing content before publishing or for sites without GSC access.
The Jaccard similarity coefficient measures the overlap between two sets. For two pages A and B, it is calculated as: |A ∩ B| / |A ∪ B| — the number of keywords shared by both pages divided by the total unique keywords across both pages. A score of 0 means no shared keywords; a score of 1 means identical keyword sets. Scores above 0.3 (30% overlap) are flagged as potential cannibalization candidates in this tool, though the threshold can be adjusted based on your content strategy.
Before publishing new content, check your existing content library for similar pages using this tool or a site:domain.com "keyword" Google search. Maintain a keyword map (a spreadsheet mapping each target keyword to exactly one primary URL). When creating new pages, ensure they target a distinct user intent or sub-topic. Use internal links to consolidate topical authority — link from your new supporting content to your primary pillar page using relevant anchor text. Regularly audit for cannibalization as your content library grows.
