Traffic dropped after a Google update: what to check, and what an update can't prove

If your traffic fell at roughly the same time as a Google update, it’s very easy to stop there.

The dates line up, so the update must have caused it.

Sometimes that will be right. But the timing alone doesn’t prove much. It tells you two things happened at around the same time. It doesn’t tell you why the site dropped, and it definitely doesn’t tell you what to fix.

I’d treat an update as one possible explanation, then try to rule everything else in or out.

Start with the date the drop actually began

Not the date someone noticed it.

Open Search Console, look at the daily chart and find where clicks or impressions really started to fall.

Then compare that with Google’s Search Status Dashboard, which lists confirmed ranking updates and the dates they ran.

Some updates roll out for days or weeks, so you’re looking for overlap rather than one exact day.

If the decline started well outside an update window, I’d be much less convinced by the update explanation.

If it started during one, fine. Keep it on the list.

Just don’t stop looking.

What changed on your own site at the same time?

This is the bit that often gets missed.

Websites change all the time.

A page gets rewritten. A developer pushes a template update. Navigation changes. A plugin is replaced. Redirects go live. Someone edits robots.txt.

Any of those can create a drop that happens to sit next to a Google update.

I’d look at the couple of weeks either side of the decline and ask what actually changed.

If nobody keeps a record of site changes, this becomes harder than it should be.

I’ve had investigations where pages had clearly been edited but there was no record of when. At that point you can say the timing is suspicious, but you can’t honestly tie one thing to the other.

That uncertainty should go in the report, not be hidden.

Look at the shape of the drop

This usually tells you more than the update name.

Did everything fall?

Or did one section fall while the rest of the site held up?

A broad decline across most page types can point towards something site-wide: an algorithm update, a technical problem, a security issue, a tracking problem.

A drop isolated to one group of pages is different.

That could be a template issue, a change in search intent, a competitor improving, a SERP layout change or simply weaker content in that section.

On the driver training investigation I worked on, roughly 60% of impressions disappeared over a few weeks in autumn 2025.

That hit every service area.

It also overlapped with a Google spam update, so an update was a credible explanation.

The second decline, in spring 2026, looked very different.

The towing pages lost visibility, but ambulance, HGV and the homepage were gaining impressions.

That doesn’t look like one site-wide event explaining everything.

Same site. Different shape. Probably a different cause.

Check rankings, but also check the results page

Clicks can fall even when rankings barely move.

That’s because the result around you may have changed.

A local search might now show ads, an AI summary and a map pack before the normal organic listings.

You can still “rank” in roughly the same place and get fewer clicks because there’s simply more above you.

That happened with some of the towing searches in the driver training investigation.

The organic result hadn’t necessarily collapsed. The page around it had become more crowded.

So I’d look at both:

• did average position actually fall?
• did the search result itself change?

They’re not the same problem.

Sometimes there isn’t a neat fix

This is the uncomfortable bit.

Google itself says that if you think a ranking update affected the site, there may not be anything fundamentally wrong with the content.

That matters.

A real drop does not automatically mean there’s a broken page waiting to be fixed.

For a larger decline, I’d still review the site properly: content quality, usefulness, duplication, technical issues, trust signals, whether the pages still match what people are searching for.

But I wouldn’t start rewriting everything just because an update happened.

That’s how you end up changing good pages without knowing what problem you’re solving.

And I’d be sceptical of anyone selling a quick “algorithm recovery” package.

There often isn’t a switch to flip.

What an update can’t prove

Even when the timing fits and the shape looks convincing, there are limits to what you can say.

You usually can’t prove exactly what Google changed or why one particular page moved. Google doesn’t publish that level of detail.

You also can’t prove that lost visibility caused lost revenue unless the business was actually tracking enquiries and sales.

That was a big issue in the driver training case.

The visibility loss was clear.

What wasn’t clear was how many bookings, if any, had been lost, because Analytics hadn’t been recording properly for almost two years and form sends and phone taps weren’t tracked.

So I described it as an opportunity cost, not proven lost revenue.

That distinction matters.

You can have strong evidence without pretending it proves more than it does.

The order I’d work through it

I’d go through it roughly like this:

1. Find the actual date the decline started.
2. Compare it with Google’s confirmed update dates.
3. Check what changed on the site around the same time.
4. Rule out technical issues, security problems and manual actions.
5. Compare the pages that fell with the ones that didn’t.
6. Check whether rankings changed or whether the SERP changed around them.
7. Fix the obvious problems first.
8. Make sure enquiry tracking is in place before the next round of changes.

If an update is still the best explanation after all of that, I’d work on the pages that matter most and give the changes time.

I would not rewrite the entire site because a chart went down.

The short version

If a traffic drop starts during a Google update, the update is a plausible cause.

It isn’t proof.

The timing, the shape of the decline, what changed on your own site and what the search results look like now will usually tell you far more.

And sometimes the conclusion is simply: this probably was update-related, but there isn’t enough evidence to say exactly why.

That’s still a useful answer.

If you want me to work through the data, my traffic decline investigation is built around exactly this kind of problem.
