Keyword Cannibalization Check

Identify queries where multiple pages on the same site are competing for rankings.

Steps

  1. Call list_properties to confirm the exact site_url.
  2. Call get_advanced_search_analytics with dimensions=query,page, sort_by=impressions, row_limit=1000 to get all query+page combinations.
  3. Group rows by query. Queries with two or more distinct pages in the top results are cannibalization candidates.
  4. For each cannibalizing query, collect: both page URLs, their individual clicks, impressions, CTR, and position.
  5. Sort candidates by total impressions (most valuable cannibalization conflicts first).
  6. Limit the output to the top 20 most severe cases.

Output format

For each cannibalization case:

  • Query: the competing keyword
  • Pages: list each URL with its metrics
  • Severity: High / Medium / Low based on impressions at stake
  • Recommendation: which page to consolidate to (pick the one with better position or CTR), and whether to use a canonical, redirect, or content merge
