Traffic dropped after a Google update A no-panic checklist: update, seasonality or breakage
A traffic drop is not yet an update. First match the drop’s start date to the timeline, then rule out seasonality and your own breakage. While an update is still rolling out, hold off on mass site changes.

In short
- A traffic drop is not yet an update: first match the start date to the timeline, then rule out seasonality and your own breakage.
- Per the Search Status Dashboard, 2026 had two core updates (27 Mar–8 Apr and 21 May–2 Jun) and four spam updates. The September spam update ran from 24 September through 8 October and covered the last week of Q3.
- While an update is rolling out it is too early for conclusions, and mass site changes are best postponed.
Update, seasonality or breakage
The three causes look alike on a chart but differ in their signs. This is the guide’s working scheme, not a Google classification.
| Sign | Update | Seasonality | Breakage |
|---|---|---|---|
| When it started | a step on the update dates | repeats year after year | a step on the day of your release |
| Who was hit | some sections or queries | all similar pages | specific URLs or templates |
| What competitors do | they fluctuate too | they fluctuate too | they are steady |
| Search Console reports | no errors | no errors | new indexing or crawl errors |
2026 update timeline
From the Search Status Dashboard, Pacific time; end dates are calculated from the dashboard’s durations. Newest rows first.
| Update | Type | Start | End |
|---|---|---|---|
| September spam | spam | 24 Sep | 8 Oct |
| August spam | spam | 18 Aug | 21 Aug |
| June spam | spam | 24 Jun | 26 Jun |
| May core | core | 21 May | 2 Jun |
| March core | core | 27 Mar | 8 Apr |
| March spam | spam | 24 Mar | 25 Mar |
According to Search Engine Roundtable the September update finished on 8 October; the one-day gap comes from calculation. Google called it a regular spam update for all languages and wrote that recovery for affected sites can take months.
I found no new core updates in the sources I checked. Coalition Technologies considers the next one inevitable, but that is the author’s forecast, not a Google announcement.
Update or breakage: a six-question check
Answer “yes”, “no” or “don’t know” about your traffic curve.
- Does the step in the chart match an update date?Cross-check with the timeline
- Was there a similar drop on these dates last year (seasonality)?Year-over-year comparison
- Did individual sections or templates drop rather than the whole site?Section split
- Did new errors appear in indexing and crawl reports?Search Console
- Were there releases in the week before the drop: robots, canonical, redirects, templates?Release log
- Did both clicks and impressions fall, not only clicks?Performance report
This guide’s own working scale, not a Google classification.
The first 14 days: what to do and what not to do
The 14-day period is the guide’s working recommendation. Basis: when launching the September update Google wrote that the rollout could take up to two weeks.
- Record the date and size of the drop, comparing the same weekdays.
- Wait for the official end of the rollout on Google’s dashboard.
- Split the data by section, country and device.
- Check your own releases and indexing reports.
What not to do
- roll the site back or mass-rewrite content before the update ends;
- delete pages that “dropped”;
- tell the client a cause before the questions above are answered.
FAQ
How do I know an update has ended?
On the Search Status Dashboard: it lists start and end dates.
What if the drop coincides with a spam update?
Google advises affected sites to check their content against the spam policies and warns that recovery can take months.
Should I expect a new core update?
There is no official announcement; forecasts are the authors’ opinions.
Can I name the cause to a client right away?
No: until checked, it is a hypothesis.
