Since mid-February, Google search results have been experiencing an abnormal level of volatility. Barry Schwartz, the founder and editor of Search Engine Roundtable, reported on March 10 about the ongoing fluctuations in Google's search output.
Despite the completion of the Google Discover Core Update on February 27, the volatility remains high. As of the publication of this report, there has been no official announcement regarding a new Core Update from Google.
Here’s a summary of the main volatility trackers:
- Semrush Sensor: 9.510 (Very High, Googlequake), remaining above 9.0 since February 15.
- Wincher: Ranged from 21 to 40 throughout the period, peaking around 40 on March 5.
- Advanced Web Ranking: Two spikes above the high mark (February 14-21 and early March), with a drop to medium between February 22-28.
- Zutrix: Ranged from 3 to 10, with a drop to 3 on February 19-20 and peaks of 10 on February 21-22 and March 3-5.
- Accuranker: Peak of 18-19 in February, with a range of 13-16 in March.
- Sistrix: Peak of 21 at the end of January and beginning of February, with a new peak of 24 in early March.
- Mangools: Consistently high levels since February 15 without noticeable drops.
- SimilarWeb: A significant decline in metrics after February 19, gradually recovering by March 10.
- Wiredboard: Metrics ranged from 7.8 to 9.3 since February 14.
- MozCast: 172 on March 9, with a historical norm of 70, showing steady growth since late January 2026.
- DataForSEO: 9.710, the highest among all trackers.
- Algoroo: Peak volatility occurred during the first two weeks of the Google Discover Core Update (February 5-27), after which the tracker’s metrics declined.
- Serpstat: 48-55% in early March against a historical norm of 20-30%, peaking at 55% on March 4 and 8.
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 suggests that Google may still be conducting unannounced core updates.
The sustained abnormal level of volatility across most trackers has been noted since mid-February 2026 and shows no signs of decreasing at the time of publication.
