If your organic traffic looked odd over the weekend, you were not imagining it. Around Saturday 18 July, the major rank tracking tools lit up at the same time, and the SEO forums started filling with the usual mix of celebration and despair. Google has said nothing, which means we are almost certainly looking at another unconfirmed algorithm update.

I want to walk you through what actually happened, why this one matters more than a typical weekend wobble, and what you should (and should not) do about it.

What the data shows

Barry Schwartz over at Search Engine Roundtable pulled together the readings from more than a dozen volatility trackers, including SEMrush, Mozcast, Sistrix, AccuRanker and Advanced Web Ranking. Nearly all of them recorded a clear spike on the Saturday.

The more interesting detail is what sits behind that spike. Volatility across the whole of the past week has been running hotter than it was around 11 July, when the last unconfirmed update landed. So this is not a single-day blip. Google appears to have been adjusting things continuously for days, with the weekend movement simply being the loudest part of it.

The 11 July connection

To make sense of this update, you need a little recent history. On 11 July, an unconfirmed update rolled through that many in the industry nicknamed the 7-Eleven update. That one appeared to reverse some of the unconfirmed changes Google made back in January 2026, meaning sites that lost ground at the start of the year saw some recovery.

Now, barely a week later, several site owners are reporting that those 7-Eleven gains are unwinding again. Others are simply seeing large swings in the queries they monitor, with no obvious pattern connecting them.

This back-and-forth behaviour is worth paying attention to. When Google flips positions one week and flips them back the next, it usually suggests live testing rather than a settled ranking change. Whatever they are experimenting with has not finished baking.

What site owners are reporting

The forum chatter paints a genuinely mixed picture. One publisher reported Google traffic surging dramatically overnight without having touched their site, whilst openly predicting the gain would vanish once things settled. Another saw rankings and click-through rates drop through the week, then recover, only for impressions to start sliding instead. A third noted their sales had returned to strong pre-11-July levels after a rough patch.

That spread of experiences is typical of an update mid-flight. For every winner there is a loser, and plenty of the movement in the first few days turns out to be temporary.

Where this fits in the wider 2026 picture

For context, the last update Google actually confirmed was the June 2026 spam update, which ran from 14 to 26 June. Before that came the May 2026 core update, running from 21 May to 2 June. Everything since late June has been unconfirmed, yet the volatility has barely let up.

That tells you something about how Google operates now. The gap between official announcements no longer means a gap in ranking changes. If you are only reacting when Google publishes a statement, you are watching the wrong signal.

What I would do this week

First, check your own data before drawing any conclusions. Open Search Console, compare the past seven days against the previous period, and separate brand queries from non-brand. Weekend traffic in July is naturally lower for many UK businesses, and this particular weekend coincides with the start of the European summer getaway, so a dip on its own proves nothing.

Second, resist the urge to change anything major. I see this mistake constantly. A site drops on a Saturday, the owner rewrites half their content by Wednesday, and then the update reverses and they have no idea whether their changes helped, hurt or did nothing. Let the dust settle for at least a week or two before you act on rankings alone.

Third, if you did lose visibility and the loss holds, look at it through a quality lens rather than a tactical one. The pattern of 2026 so far, with spam updates, core updates and constant unconfirmed adjustments, points in one direction: Google keeps re-evaluating which sites deserve their positions. Thin pages, weak topical coverage and content written for the algorithm rather than the reader are the usual casualties.

And finally, keep a simple log. Note the dates of these volatility spikes alongside your own traffic changes. When the next confirmed update arrives, that log becomes the difference between guessing and knowing.

The short version

An unconfirmed Google update hit around 18 July, following unusually high volatility all week. It may be partially reversing the 11 July changes, early movement looks unstable, and nobody should be making drastic decisions off the back of it yet. Watch your data, hold your nerve, and if your traffic has taken a knock that does not recover, get a proper diagnosis before you start changing things.
