This detects keyword cannibalization by analyzing multiple pages for overlapping keywords, similar search intent, and competing metadata. You'd use it when auditing existing content or before publishing new pages that might compete with what you already have. It outputs a conflict matrix showing which pages are fighting for the same keywords, then recommends whether to consolidate, differentiate, or redirect. The approach is solid: it checks titles, meta descriptions, headers, and content similarity, then suggests concrete fixes like merging weak pages or rewriting for different intent. Honestly most useful as a proactive check rather than waiting until your rankings tank because three blog posts are all targeting the same longtail keyword.
