If your rankings wobbled in late September, you're not imagining it. Google has had its busiest year for spam enforcement since 2021, and the changes to how people search are moving just as fast. A good SEO agency UK businesses can trust will tell you the same thing: don't panic, don't chase tricks, and fix the fundamentals.
Here's what has actually changed in 2026, what it means for your site, and the practical steps worth taking this month.
What Google changed in 2026
The headline event is the Google spam update that began on 24 September 2026. It's the fourth spam update of the year, following March, June and August. The earlier three wrapped up within a few days. This one came with a window of up to two weeks, and industry trackers reported several waves of volatility, with the final phase landing around 4 to 6 October.
Google hasn't said it targets one particular spam policy. That matters. When there's no named target, the safest assumption is that Google is tightening its automated detection across the board: thin content, scaled low-value pages, manipulative links and anything else that breaks its published spam policies.
Earlier in the year, the May 2026 core update ran from 21 May to 2 June, roughly 12 days, and it hit harder than the March one for many sites. Google also published its first official guide to optimising for AI features in Search, and its message was blunt: there is no separate playbook. Strong SEO fundamentals are still what AI-driven results rely on.
Why AI search changes the job, not the rules
Google says its AI features now reach well over a billion people each month. AI Overviews and AI Mode pull from the same index and lean on the same quality signals as normal results. So if a page is thin, unclear or untrustworthy, it won't be quoted by an AI answer either.
What does change is how you measure success. Rankings and clicks are no longer the whole story. Being cited, named and recommended inside an AI-generated answer is becoming its own source of visibility. Google has started to reflect this in Google Search Console, with reporting that shows impressions inside AI features. Google has also extended Preferred Sources, which lets people pick the publishers they trust, into AI answers. That rewards businesses with genuine audience loyalty, not those with the cleverest tactics.
For UK businesses, the takeaway is simple. The brands that win are the ones Google, and the AI built on top of it, can clearly identify as real, local, experienced and useful.
Five things to do this month
1. Check the timing before you change anything. Compare any traffic drop against the update dates in Search Console. Changing content mid-rollout makes it impossible to know what caused what. Wait for the dust to settle, then act on evidence.
2. Audit for scaled, low-value content. If you've published batches of near-identical location pages, AI-written filler or pages with no real expertise behind them, tidy them up. Merge, improve or remove. Quality beats volume every time.
3. Review your backlinks. Links earned through genuine PR and relevant industry coverage hold up. Links bought from networks or directories are a liability. A decent SEO agency UK teams rely on will audit this before building anything new.
4. Get your reviews and local signals in order. Your Google Business Profile, citations and reviews carry real weight with local searchers. If you serve a specific area, proper local SEO is still one of the highest-return investments you can make. Keep reviews honest, too. Under UK law, fake or concealed-incentive reviews are now banned, and the Competition and Markets Authority can act directly. The government's fake reviews guidance (CMA208) sets out exactly what's allowed.
5. Structure content so machines and humans can both use it. Clear headings, direct answers, accurate schema and named authors make your pages easier to quote. This is the heart of answer engine optimisation, and it pairs naturally with generative engine optimisation, which focuses on getting your brand cited inside AI-generated responses. Neither replaces classic SEO. They sit on top of it.
Don't forget what happens after the click
Rankings only pay off if visitors turn into enquiries. Many businesses invest heavily in traffic and then lose it on a slow page or a confusing form. Pairing search work with conversion rate optimisation means the visitors you've earned actually get in touch. Meanwhile, if you need leads while organic rankings build, paid search can fill the gap.
That's the logic behind Breeze Development's approach: growth that actually sticks, not a spike that disappears with the next update.
How to choose an SEO agency UK businesses can rely on
With updates arriving this often, the agency you pick matters more than ever. Here's what to look for in an SEO agency UK buyers can trust:
- Commercial focus. They should talk about enquiries, sales and revenue, not just rankings and traffic.
- No shortcuts. Anyone promising guaranteed page-one results or quick link packages is a risk after a spam update.
- Clear reporting. You should see what was done, why, and what it produced.
- Full ownership for you. You keep access to your site and your data, with no lock-in.
- Evidence. Look for named clients and measurable outcomes, not vague claims.

Frequently asked questions
What is a Google spam update? It's an improvement to Google's automated systems for detecting content and tactics that break its spam policies. Sites that break the rules may drop in rankings or disappear from results.
How do I know if the September 2026 spam update hit my site? Check Search Console for ranking and traffic changes between 24 September and early October. Compare them with the update dates before making changes to your pages.
Should I change my site while an update is rolling out? Generally no. Monitor first and wait for the rollout to finish. Reactive changes mid-update make it impossible to tell what actually caused any shift.
Do I need separate SEO for AI Overviews and AI Mode? No. Google says the same fundamentals apply. Clear structure, genuine expertise and technical health matter most. Specialist AEO and GEO work simply builds on that foundation.
How long does SEO take to work in the UK? Technical fixes can show results in 30 to 60 days. Competitive rankings usually take three to six months of consistent work, depending on your market and starting point.
How much does an SEO agency UK businesses hire charge? It varies with competition, your site's condition and your goals. Reputable agencies scope each project individually and give you a transparent, custom proposal.
