Core Web Vitals: How to audit and assess it
This guide covers Core Web Vitals. Use one real case and keep the next step clear.
What matters in practice
Key rule: Review LCP, INP and CLS with field data and fix the cause separately for each page type.
Use the same short list each time. This keeps the check easy to review.
A reliable way to work
Set one question before the test. Decide what result should count.
Name one owner. Record the current state.
Change one point only. Then check the result.
If money, customers or public claims are involved, add a human review.
Check the result again later. Keep only what helps the goal.
