Google rankings swung and 14 third-party trackers showed elevated readings

A site owner who watched clicks fall on 20 October had to answer one question before the next working day: is this Google, is this tracking, or is this the site. Search Engine Roundtable's Barry Schwartz reports elevated volatility across every major third-party tracker on 20 and 21 October 2026 and calls it an "unconfirmed Google search ranking update". Google has not announced anything, and the signal is on the trackers plus the community reports rather than on an official page.

The trackers and what they show

The post names 14 tools showing elevated readings on the two days: AccuRanker, Algoroo, AWR, CognitiveSEO, DataForSEO, Mangools, Mozcast, SEMRush, Serpstat, SimilarWeb, Sistrix, Wincher, Wireboard and Zutrix. Schwartz adds that some, "maybe all", of these tools are themselves struggling to measure the volatility, so the readings may understate rather than overstate what is happening.

The last confirmed Google update ended on 8 October, when the September 2026 spam update finished rolling out at 4:37 am ET. Schwartz had also flagged an unconfirmed swing on 16 October. The 20 and 21 October signals land in the quiet window between those and a possible next core update.

What site owners are reporting

The comments on the post carry specific numbers. One site owner reports "clicks down about 60 to 70 percent" despite still ranking in the top three. Another reports traffic "up 70 percent over last October". A third describes real-time traffic jumping from 10 people to 40 and back within minutes, which reads like results being swapped in and out of a position rather than steady rankings.

Google Discover shows up in the comments more than usual. One site reports Discover traffic crashing at 2:00 pm, the feed going "completely empty for days" and recovering at a lower level, with stories "replaced by rivals" sooner than they used to be. Glenn Gabe, named in the post, confirmed two YMYL niche sites dropping out of the SERP including on their own brand queries on 13 October and recovering at 8:15 pm on 16 October.

What to do in the next working day

Three steps a site owner can take without waiting for a confirmation that may never come. First, in Google Search Console, compare the 20 to 21 October window against the previous Monday and Tuesday, by page and by country, so an overall drop can be split into pages that moved and pages that did not. Second, run the trackers against the ten queries that matter most, rather than reading the headline volatility score; a flat index average often hides a very noisy top ten. Third, hold technical changes until a pattern is clear, because publishing a fix for an unconfirmed update that then turns out to be a transient swing can be worse than leaving the site alone.

What the post does not say is whether a core update is on the way, how long the swing will last, or whether this is the first wave of something larger or the aftershock of the September spam update. All three are possible and none is confirmed. The signal is strong enough that a serious site owner should look at their own numbers today, not strong enough to publish anything that assumes a cause.
