If you run display ads (like AdSense), they are often the biggest threat to your Core Web Vitals. Two rules keep you safe:
- Always reserve a fixed height for each ad container.
- Don't stack ads above the fold where they delay your LCP and shift your layout.
Good ad UX and good Core Web Vitals are the same goal: don't surprise the reader.
How to measure (free tools)
- PageSpeed Insights — lab + real-world field data for any URL.
- Search Console → Core Web Vitals report — see which page groups fail at scale.
- Chrome DevTools → Lighthouse — debug a single page locally.
Always trust field data (real visitors) over lab data when they disagree — Google ranks on what real users experience.
