Since mid-February, the volatility of Google search results has been at an abnormal level. Barry Schwartz, the founder and editor of Search Engine Roundtable, published a monitoring report on March 10, detailing the overall volatility of Google search results.
Despite the completion of the Google Discover Core Update on February 27, fluctuations remain unusual. At the time of this publication, no official announcement regarding a new Core Update from Google had been made.
Here’s a summary of the main volatility trackers:
- Semrush Sensor: 9.510 (Very High, Googlequake), has not dropped below 9.0 since February 15.
- DataForSEO: 9.710, the highest reading among all trackers.
- MozCast: 172 on March 9, with a historical norm of 70, showing steady growth since late January 2026, with a sharp acceleration in February.
- Serpstat: 48–55% in early March, with a historical norm of 20–30%, peaking at 55% on March 4 and 8.
- Advanced Web Ranking: Two spikes above the high mark (February 14–21 and early March), with a drop to medium between February 22–28.
- Sistrix: Peak of 18–19 in February, with a range of 13–16 in March.
- Wincher: Range of 21–40 throughout the period, peaking around 40 on March 5.
- Wiredboard: Readings between 7.8–9.3 since February 14.
- Accuranker: Peak of 21 at the end of January–beginning of February, new peak of 24 in early March (higher than previous), at 12 on March 10.
- Mangools: Consistently high levels since February 15 without noticeable drops.
- SimilarWeb: Significant decline in metrics after February 19, with gradual recovery by March 10.
- Zutrix: Range of 3–10, with a drop to 3 on February 19–20 and peaks up to 10 on February 21–22 and March 3–5.
- Algoroo: Peak volatility occurred during the first two weeks of the Google Discover Core Update (February 5–27), after which the tracker’s readings decreased.
In SEO communities, webmasters are reporting losses of up to 97% in organic traffic (from 200,000 to 5,000 visits per day), while some projects simultaneously report sharp increases in rankings and sales. Schwartz believes that Google is likely continuing to conduct unannounced core updates.
The sustained abnormal level of volatility across most trackers has been recorded since mid-February 2026 and shows no signs of decreasing at the time of publication.
