Steps

Once connected (see setup above), use the Lighthouse Audit tool:

  1. Run a baseline audit before making changes
  2. Deploy your changes
  3. Re-run the audit and ask OpenClaw to compare results
  4. Review improvements and address any regressions

Example Prompt

Try this with OpenClaw using the Lighthouse Audit tool
Run Lighthouse on mysite.com/page now and after I deploy. Compare the scores.

Tips

  • Keep a log of before/after comparisons to track optimization progress over time
  • Ask for the percentage change in each metric, not just the raw scores
  • Use comparisons to build a case for continued performance investment
