Google's search weather is rough on March 30. SERP volatility is running at 6.7/10 today according to WireBoard's tracker, with some tools screaming hotter than others, which usually means rankings are moving even if Google has not confirmed a broad update.
Across the main SEO news sources checked today, there does not appear to be a freshly confirmed Google core or spam update on March 30 itself. The most concrete Google-side development in the last 48 hours is still the March 25 Search Central documentation update: Google added 3DModel markup support for merchant listings and clarified product variant handling. That matters mostly for ecommerce sites with rich product pages, not for the average local business site.
The bigger practical story is uncertainty. Search Engine Journal recently highlighted how easily false "update" rumors can spread in Google and AI Overviews, so site owners should not chase every ranking wobble. If traffic dipped today, check Search Console, compare page groups, and fix obvious quality or technical issues before making big changes.
