Evidence review
What to inspect before changing anything
Start with the delivered website and the real user journey. Record the current state so the team can distinguish an observed problem from an assumption and compare the same surface after deployment.
- 01Save both complete reports and timestamps
- 02Compare canonical URL, evidence breadth and status
- 03List intended public changes between captures
Implementation
A practical improvement plan
Make the smallest coherent change that solves the observed problem. Keep normal code review, accessibility, security and product checks in the loop instead of optimizing for the scan alone.
- 01Group changes into coherent releases
- 02Investigate unexpected driver movement
- 03Keep security and footprint comparisons separate
Verification
How to verify the result
Verification should test the intended outcome and the most likely regression. Use the production delivery path whenever headers, caching, rendering or third-party services affect the result.
- 01Repeat anomalous scans
- 02Verify delivered assets match the intended release
- 03Check user-facing quality alongside metric changes
Common pitfall
A shortcut to avoid
Choosing the best result from repeated scans without explaining variance turns measurement noise into a performance claim.
