What changed
Google's March 2026 core update completed on April 8 after a 12-day rollout
SERP volatility hit 9.5/10 on SEMrush Sensor, the highest of 2026 so far
Over 55% of monitored sites experienced ranking shifts, with some reporting 20-35% organic traffic drops
What it means
The pattern is clear: Google is moving rankings away from intermediary sites toward destination sources. Official sites, specialist publishers, established brands and dominant platforms gained visibility. Aggregators, directories and comparison-driven sites lost ground. If your site adds a genuine layer of value (owned data, original research, direct expertise) you are on the right side of this trend. If you sit between the searcher and the answer without adding much, you are increasingly exposed.
What to do
Check Google Search Console for ranking and traffic changes since March 27
Compare page-level performance before and after the update window
Identify pages that lost visibility and assess whether they offer unique value or just repackage others' content
Prioritise content that uses proprietary data, direct experience or original analysis
