If your traffic did something strange between 15 and 16 September, you weren’t imagining it. Google Search got noisy again this week, and it’s not an isolated blip — it’s the third round of instability since late August, and the pieces are starting to connect.
Barry Schwartz at Search Engine Roundtable flagged a “huge spike in chatter” on the morning of 15 September, with third-party rank trackers picking up the same signal within hours. His own take: Google probably won’t confirm anything, and it rarely does for volatility like this. Fair call — but the pattern is hard to miss once you line it up against what’s already happened this month.
Not the first blip this month
This is the third wobble since late August, not the first.
Google’s August 2026 spam update ran from the 18th to the 21st, and it hit harder than the previous two spam updates this year. By one tracking estimate, roughly 16.7% of URLs that had been sitting in the top 10 fell past position 100 — against a normal churn rate closer to 9%. Almost double.
Then, around 4 September, a batch of large sites tracked publicly by SEO consultant Glenn Gabe fell off a cliff in Search and Discover. Nine days later, on the 13th, most of them bounced most of the way back. Gabe called it “wild” on X, and it’s the sort of reversal that makes a single week’s ranking snapshot almost useless on its own — what looks like a loss on Monday can be gone by the following weekend.
Now, two days after that, another spike. Whether 15 September is a distinct new event or just the tail end of August’s spam update still working its way through is genuinely unclear. Google’s own Search Status Dashboard hadn’t logged anything new as of this week.
What SEOs are actually seeing
Forum chatter on WebmasterWorld is messier than a clean “update” story. Some are reporting AI Overviews surfacing odd, unrelated results. Others say entire keyword sets they’d ranked for got swapped out overnight for pages they’ve never seen before — the kind of wholesale reshuffle that usually only shows up during a genuine core update, not routine churn. A few mentioned Discover traffic drying up at almost the same hour, two days running, which points to something more systemic than the usual daily noise.
What to actually do about it
Tearing your content apart every time the volatility trackers spike is a good way to do more damage than the update itself. A calmer approach:
Pull query- and page-level data before you even look at the sitewide graph. It’s entirely possible to lose ranking positions while traffic holds steady — or lose half your traffic with no position movement at all.
Check your numbers against the 18–21 August window, not just the last 48 hours. If a drop traces back to the spam update and never actually recovered, this week isn’t a new problem. It’s an old one resurfacing.
If any part of your site carries third-party or guest content, it’s worth a look even outside the EU. Google changed how it evaluates that content for EEA searches in late August, and enforcement approaches like this tend to go global eventually rather than staying regional.
And give it more than a day. Recovery from unnamed, unconfirmed ranking events has historically taken anywhere from a few days to a few weeks — sometimes longer.
We’ll keep watching how this settles and update this post if Google says anything official. Based on the last few rounds, that could be a while.
