When a core update lands, the instinct is to guess at causes. A more reliable approach is to work through a consistent diagnostic process before drawing conclusions.
Steps to take
- Segment traffic changes by page type, query type, and template — broad drops usually point to different causes than isolated ones
- Check whether competitors in the same space moved similarly, which suggests a niche-wide shift rather than a site-specific penalty
- Review the pages that moved most against Google’s published quality guidance rather than rumor-driven theories
- Wait for the rollout to complete before making large changes — rankings can fluctuate mid-rollout
What to avoid
Avoid reactive rewrites based on a single data point. See technical SEO for a broader diagnostic checklist. More in Research & Data.
