I remember the first time I saw Core Web Vitals all green and felt triumphant—only to watch some of my most important pages slide down the SERPs a few weeks later. If that’s happened to you, you’re not alone. Green CWV is a great start, but it’s not a magic bullet. I’ve compiled a practical, field-tested checklist of things I audit when Core Web Vitals look healthy but rankings still fall. Work through these items methodically and you’ll usually uncover the real problem.
Start with data — confirm the drop and its scope
Before anything else, validate what’s happening and where:
Sometimes what looks like a ranking drop is actually a reporting artifact or a decline for a subset of queries. Confirm the problem before digging deeper.
Check for algorithm updates and SERP volatility
I always check whether a known Google broad core update, spam update, or product review update rolled out around the time of the drop. These updates can change how Google weights content, E-E-A-T, or intent matching.
Audit content relevance and intent
Even with great CWV scores, content can be mismatched with user intent. When intent shifts (e.g., from informational to transactional), pages that previously ranked well can lose visibility.
Review on-page SEO and metadata
Meta titles, descriptions, H1s, and structured data still matter for CTR and relevancy signals.
Inspect technical SEO beyond Core Web Vitals
I’m careful to separate CWV from other technical factors. Pages can be fast and stable yet not crawlable or indexed correctly.
Backlink and referral profile checks
Changes in your link profile or competitors gaining strong links can impact rankings quickly.
Examine UX and conversion signals beyond CWV metrics
Search engines increasingly use engagement signals (dwell time, pogo-sticking) to judge satisfaction.
Check for duplicate or syndicated content issues
Duplicate content—internal or syndicated—can dilute rankings.
Validate structured data and rich result eligibility
Schema errors can cause you to lose rich snippets, which often drive higher CTRs and perceived relevance.
Review server and hosting issues
Sometimes performance looks good in lab tests but the origin server has intermittent problems.
Audit internal linking and site architecture
Internal links distribute authority and help Google understand page importance. A recent change here can shift rankings.
Look at localization, hreflang, and canonical cross-country issues
If you operate in multiple languages or markets, misconfigured hreflang can lead to the wrong country or language page being shown.
Confirm no manual actions or security issues
Manual penalties or hacked content will tank rankings regardless of CWV.
Use server logs and search console data for deeper clues
Server logs reveal how Googlebot behaves on your site. I often find crawl budget changes or unexpected blocking that aren’t visible elsewhere.
| Audit Area | Quick Check | Priority |
|---|---|---|
| Intent & Content | Compare top SERP pages to yours | High |
| Indexation/Crawl | Search Console + Screaming Frog | High |
| Backlinks | Lost/gained link analysis | High |
| Structured Data | Rich Results Test | Medium |
| Server/Hosting | Log file & uptime checks | Medium |
| User Signals | Analytics & session recordings | Medium |
Tools I rely on for these audits: Google Search Console, Google Analytics / GA4, Screaming Frog, Ahrefs, Semrush, PageSpeed Insights, Chrome DevTools, Hotjar/FullStory, and server log analyzers. I typically create a prioritized action plan from the checklist above and tackle the highest-impact items first—content intent fixes, indexation problems, and lost backlinks usually move the needle fastest.
If you want, send me the URL structure of the affected pages (or a few sample URLs) and I can point you to the most likely culprits based on the patterns I’ve seen. I often spot the issue within a few minutes of looking at the SERP and page characteristics.
