Short answer first, since that’s what you came for: yes, most established agencies now offer some form of AI search optimisation. But “offer” and “do properly” are two very different things, and the gap between them is where a lot of client budgets quietly disappear.
Here’s the problem. You’ve noticed customers finding businesses through ChatGPT, Perplexity, and Google’s AI Overviews instead of ten blue links. Your competitors are showing up in those answers. You’re not. And when you ask a UK digital marketing agency whether they handle this, most say yes without being able to explain what that actually means in practice.
That’s frustrating on its own. Worse, if you sign a retainer based on that vague “yes,” you may spend months paying for optimisation that never touches AI search at all because the agency is still reporting on traditional rankings, not the ones actually shifting your visibility.
This article answers the question properly: which UK agencies genuinely handle GEO, what it costs, and — because this rarely gets mentioned anywhere what happens to your ad accounts and your money once you sign that contract.
The Quick Answer: Yes, But Coverage Varies Wildly
Generative Engine Optimisation, or GEO, is the practice of getting a business mentioned, cited, or recommended inside AI-generated answers rather than just ranking on a results page.
Most mid-sized and larger UK agencies have added GEO to their service list over the past year. Fewer have actually restructured their process around it.
The difference shows up fast. An agency doing GEO properly will look at how your content gets cited by AI models, structure pages to answer questions directly, and track mentions inside AI Overviews. An agency bolting GEO onto old SEO reports will just add a slide with “AI Search” written on it.
What GEO Actually Means for a UK Business
Traditional SEO chases rankings. GEO chases citations getting your business named as the answer, not just linked as an option.
For a UK online marketing agency, that shift changes the actual work involved:
- Content needs to answer specific questions clearly, near the top of the page, not buried under 800 words of introduction.
- Structured data and clear entity information (your business name, location, services) matter more than keyword density ever did.
- Reviews and third-party mentions carry weight, because AI models cite sources they consider credible.
None of this replaces SEO. It sits alongside it. But an agency that hasn’t adjusted its process for it is still selling you 2022’s service under a new label.
How to Tell If a UK Digital Marketing Agency Really Offers GEO
Questions Worth Asking Before You Sign
Ask directly whether they track AI Overview mentions and citations, not just search rankings. A real answer includes specific tools or reporting methods, not a general nod toward “we monitor everything.”
Ask how their content structure changed in the last year. If nothing changed, GEO probably wasn’t part of it.
Ask for one example of a client now appearing in AI-generated answers. Agencies genuinely doing this work usually have at least one case ready to show.
The Hidden Cost Most Agencies Don’t Mention
This is the part that rarely makes it into agency pitch decks, and it matters more than most of the GEO conversation.
Who Actually Owns Your Ad Account?
Plenty of UK agencies set up and manage Google Ads or Meta accounts under their own agency login, not yours. It works fine while you’re a client.
The trouble starts when you leave. Some agencies keep the account, along with years of performance history, conversion data, and audience targeting built from your ad spend. You walk away with nothing but a fresh account and a blank slate.
Before signing anything, ask a simple question: is the ad account created under my business’s own login, with agency access granted as a user, or under theirs? That single detail decides who owns the data when the relationship ends.
Secret Management Markups on Media Spend
The second issue is quieter still. Some agencies quote a management fee, then also apply a markup directly on the ad spend itself, sometimes 10 to 20% without stating it clearly in the contract.
So a client thinking they’re spending £1,000 on ads might actually be spending £850 on ads and £150 disappearing into an undisclosed markup, on top of the agreed management fee. It’s not usually illegal. It’s just rarely explained upfront, which is exactly why it needs asking about directly.
UK Digital Marketing Agency Pricing Benchmarks
Here’s what fair, transparent pricing typically looks like across UK business sizes right now:
| Business Size | Average Monthly Retainer | Typical Included Services | Expected Outcome |
| Small Local Business | £800 – £2,000/mo | Local SEO, basic Google Ads, Google Map updates | More local leads and calls |
| Growing / Mid-Sized | £2,500 – £6,000/mo | SEO, Paid Search, Social Ads, Content Creation | Steady lead volume & sales growth |
| Large / Enterprise | £7,000 – £15,000+/mo | Full multi-channel strategy, PR, custom AI optimisation | Market share & brand dominance |
If a quote sits well outside these ranges with no clear explanation of extra scope, that’s worth a direct conversation before signing.
A Real Example: Losing a £40,000 Ad Account Overnight
A mid-sized retailer in Leeds worked with an agency for three years, building a Google Ads account that had accumulated genuinely valuable conversion data from roughly £40,000 in annual spend.
When the relationship ended over a disagreement on reporting, the retailer discovered the account had been created under the agency’s own manager account from day one. Access was revoked within a week. Three years of audience data, conversion history, and campaign learning went with it.
Rebuilding that performance history from a blank account took the better part of six months. The lesson wasn’t about the agency’s ad skills, which had actually been solid. It was about a single line in the onboarding paperwork nobody had questioned at the time.
What to Look for in an Online Marketing Agency UK Wide
Ownership and transparency matter as much as creative output or reporting dashboards. A genuinely trustworthy online marketing agency UK businesses can rely on should set up every ad account under the client’s own business login, disclose any markup on media spend in writing, and explain their GEO process with specifics rather than buzzwords.
This is where The Boss Digital UK takes a different approach worth mentioning: every ad account is built under the client’s own login from day one, media spend markups are stated plainly in the contract, and GEO reporting covers actual AI citation tracking rather than a rebranded SEO report. It’s a small set of practices, but they’re exactly the ones that protect a business three years down the line.
Common Mistakes Businesses Make When Choosing an Agency
A handful of patterns show up again and again:
- Signing a retainer without asking who owns the ad accounts.
- Accepting “we do AI search too” without asking for specifics or examples.
- Comparing agency quotes purely on the headline retainer, ignoring media spend markups.
- Assuming a bigger agency automatically means better GEO coverage size and AI-readiness aren’t the same thing.
Frequently Asked Questions
Do UK marketing agencies really optimise for AI search results? Many now do, but the depth varies significantly. The most reliable sign is whether they track actual citations in AI-generated answers rather than just traditional search rankings.
Who owns my Google Ads account if I use a UK digital marketing agency? It depends entirely on how the account was set up. Ask whether it’s created under your business’s own login with agency access granted separately, since this determines what you keep if you leave.
Do agencies charge extra on top of ad spend? Some do, through an undisclosed markup on media budgets in addition to the management fee. This should be stated clearly in any contract before signing.
The Bottom Line
A UK digital marketing agency that genuinely handles GEO will be specific about how, not just confident that they do. And before any contract gets signed, ad account ownership and media spend markups deserve the same scrutiny as the marketing strategy itself.
Ask the direct questions early. The agencies worth working with will have straightforward answers ready.
