You open your laptop, check where your website sits on Google, and it's not where you left it. Yesterday you were third. Today you're eighth. Nobody touched anything.
If that's you this week, here's the likely reason. Google's November 2026 core update started rolling out on Tuesday 10 November, just after 6pm UK time, and it's still going. Google says it could take up to two weeks.
So before you start rewriting your homepage at 11pm, read this first.
What is a Google core update?
A core update is Google changing how it decides which pages deserve the top spots. It happens a few times a year. This is the third of 2026, after March and May, and the first in nearly six months.
It isn't aimed at any one website, industry or country. This one covers every country and every language. Google calls it "a regular update designed to better surface relevant, satisfying content", which is a polite way of saying the furniture is being moved again.
The simplest way to think about it: imagine you keep a list of your ten favourite restaurants. Every so often you redo the list. Some places move up, some move down and a couple of new ones appear. The ones that dropped didn't get worse overnight. You just looked at everything again.
What you might see on your own website
While the update rolls out, rankings can jump about. A page can climb on Wednesday, slide on Friday and end up somewhere different again the week after. That's normal, and it tells you very little yet.
A few things worth knowing:
A dip this week is not a penalty. Real penalties show up in the Manual actions report in Google Search Console. A core update never does.
Google's own guidance says most sites won't need to worry about a core update and may not even notice one.
If you do drop, it doesn't mean your page is bad. It often means Google now thinks another page is a better fit for that search.
What not to do while it's rolling out
This is the part where most of the damage gets done. Not by Google, but by panicked people with website logins.
Don't rewrite your homepage because of three days of data.
Don't delete pages that have dipped. They may bounce straight back.
Don't buy a quick fix. Nobody can "fix" a core update for you, because there's nothing broken to fix.
Don't check your rankings six times a day. It won't help and it'll ruin your week.
What to do instead
Google's advice is refreshingly simple, and it's mostly about patience.
1. Let it finish. If the rollout takes the full two weeks, it ends around Tuesday 24 November. That's three days before Black Friday. Thank you, Google. It may also overrun: the December 2025 update took 18 days.
2. Then wait one more full week. Google recommends leaving at least a week after the update finishes before you draw any conclusions.
3. Then compare the right dates. Open Google Search Console, go to the Performance report and compare that settled week with a week before 10 November. If the update ends on 24 November, that means looking in early December and comparing against 3 to 9 November.
4. Look at pages and searches, not just the total. Which pages moved? Which searches? One page slipping for one phrase is very different from the whole site sliding.
5. Rule out the boring stuff. A dip can have nothing to do with Google. Check the site is loading, your tracking is still working and nobody changed anything on the site around the same date.
If you don't have Search Console set up, this is your sign. It's free, it's Google's own tool and it's the only place you'll get a straight answer about what changed.
If your rankings have dropped once it's all settled
A small wobble is not a reason to do anything. A big, lasting drop is worth a proper look.
When you look, be straight with yourself about the pages that fell. Who are they really written for? Do they answer the question someone typed in, or do they circle round it? Would you be happy to hand that page to a customer standing in front of you? Pages built from your own experience, prices, process and opinions tend to hold up better than pages that repeat what everyone else has already said.
Two things to be realistic about. Improvements take time to show, sometimes months. And sometimes the lift only arrives with the next core update, which on this year's form could be a while. That's not a reason to wait. It's a reason to start with the pages that matter most to your business.
If you'd like a structure for that review, our small business marketing audit walks you through what to check, and our guide to why your marketing isn't working will help you work out whether search is the real problem or just the most visible one.

The Black Friday bit
If you've got Black Friday offers going out, the timing is a nuisance. Your offer pages could move around in search right when you need them.
The answer is not to rely on Google alone that week. Email your list. Post about it. Tell your existing customers directly. Those are the channels you control, and they don't reshuffle themselves on a Tuesday evening.
The short version
Don't panic. Don't tinker. Let the update finish, give it a week, then look properly in Search Console in early December.
And if you get to December, the numbers have dropped and you're not sure what you're looking at, that's exactly the sort of thing we help with. Book a free half hour chat and bring your Search Console login. We'll tell you what we see.
