March 2026 core update confirmed as the most volatile since 2023. One in four top-10 pages fell out of the top 100.
The March update finished its 12-day rollout on April 8. The data coming in is stark: nearly 80% of top-3 rankings shifted and one in four pages in the top 10 fell out of the top 100 entirely. YMYL niches (health, finance, home services) took the hardest hits. Pages lacking verified author credentials or relying on thin AI-generated content dropped 20% or more in traffic within days. Strong brands with owned data and firsthand expertise won. Intermediary content lost, badly.
