  • Data Sources

    > See CONNECTORS.md for tool category placeholders.

    With ~~SEO tool + ~~web crawler connected:
    Claude can automatically pull page HTML via ~~web crawler, fetch keyword search volume and difficulty from ~~SEO tool, retrieve click-through rate data from ~~search console, and download competitor pages for comparison. This enables fully automated audits with live data.

    With manual data only:
    Ask the user to provide:

  • Page URL or complete HTML content

  • Target primary and secondary keywords

  • Competitor page URLs for comparison (optional)
  • Proceed with the full audit using provided data. Note in the output which findings are from automated crawl vs. manual review.

    Tips for Success

  • Prioritize issues by impact - Fix critical issues first

  • Compare to competitors - See what's working for top rankings

  • Balance optimization and readability - Don't over-optimize

  • Audit regularly - Content degrades over time

  • Test changes - Track ranking changes after updates
  • > Scoring details: For the complete weight distribution, scoring scale, issue resolution playbook, and industry benchmarks, see references/scoring-rubric.md.


    Save Results

    After delivering audit or optimization findings to the user, ask:

    > "Save these results for future sessions?"

    If yes, write a dated summary to memory/audits/on-page-seo-auditor/YYYY-MM-DD-<topic>.md containing:

  • One-line verdict or headline finding

  • Top 3-5 actionable items

  • Open loops or blockers

  • Source data references
  • If any veto-level issue was found (CORE-EEAT T04, C01, R10 or CITE T03, T05, T09), also append a one-liner to memory/hot-cache.md without asking.
