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.
- 01Inventory script origins and tag-manager rules
- 02Map each script to data access and product purpose
- 03Review integrity, CSP and change-control options
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.
- 01Remove unused tags and reduce privileges
- 02Self-host stable assets when appropriate
- 03Constrain sources and monitor unexpected changes
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.
- 01Block each integration and test graceful degradation
- 02Inspect requests and storage after consent choices
- 03Recheck the inventory on every vendor change
Common pitfall
A shortcut to avoid
A familiar analytics or support vendor is not a reason to grant indefinite access to every page and user state.
