Overview

The Search Console Cannibalization MCP server connects AI models to Google Search Console data for identifying keyword cannibalization. This occurs when several pages on a domain rank for the same search query, causing Google to divide impressions and clicks across them, reducing overall visibility and traffic. The server enables querying historical performance metrics like impressions, clicks, positions, and CTR by query and page, then applies detection logic to surface issues.

Key Capabilities

  • Retrieval of Search Console performance reports filtered by query, page, country, or device.
  • Detection of cannibalization by scanning for queries with multiple page entries from the same property in top positions.
  • Calculation of impression share and traffic loss estimates for competing pages.
  • Export of structured data for further processing, such as CSV reports of affected keywords and URLs.

Use Cases

  1. Pre-publish content review: Before launching new articles, query recent data with performance_report to check if new page targets overlap existing high-performing queries, avoiding new cannibalization.

  2. Monthly SEO audit: Run full-site analysis on the past 16 months of data to list top cannibalized keywords, prioritize pages for noindex or redirects.

  3. Post-redesign analysis: After site restructure, compare before/after data to verify if mergers resolved cannibalization on core queries like product names.

  4. Agency client reporting: Aggregate data across multiple properties to deliver client dashboards highlighting cannibalization risks and resolution steps.
