How to Use This Data
Correlate Traffic Drops
Compare your Google Analytics or Search Console traffic drops against the update dates above. Timing alignment within 1–2 weeks strongly suggests an algorithmic cause.
Category Signals
Core updates affect overall ranking quality. Spam updates target manipulative link building. Content updates reward helpful, people-first content. Knowing the category helps you diagnose which area of your site needs attention.
Recovery Timelines
Most algorithmic recoveries require waiting for the next update in the same category. Core update recoveries typically take 2–6 months of sustained quality improvements before the next core update confirms the changes.
