Disclosure first. This is Julian Goldie's own site and Goldie Agency is his own agency, so the case for number one is made with receipts you can check yourself. The other nine are London agencies, and they are written up fairly. If you would rather talk than read, Book a free SEO strategy session and get a plan for your own site.
London buyers now ask ChatGPT, Perplexity and Google AI Overviews for recommendations before they click a result, so your agency has to win in the rankings and in the AI answers. For the national picture, see our AI SEO agency UK guide.
What to Look For in a London AI SEO Agency
Four things separate a real AI SEO agency from an old agency with a new label.
- AI-first production. AI agents should handle the drafting and publishing, with people owning strategy and quality. The Agent OS guide shows what that set-up looks like.
- AI-answer visibility. The agency should work on getting you cited in ChatGPT, Perplexity and AI Overviews, and it should show you how it tracks that.
- Links and authority. AI engines mention brands the web already trusts, and links still build that trust. Julian's free link building book covers the basics.
- Proof you can inspect. Published results and public methods beat a slide deck every time.
Would you rather learn the system than hire it out? The AI Profit Boardroom is where Julian teaches AI SEO step by step, and the 200+ AI SEO Prompts are a free place to start.
How We Ranked
This ranking is this site's editorial call. It is not an independent audit, and we have not hired the other nine agencies as clients. We ranked on four criteria.
- Public proof of AI-search results that a reader can check.
- A clear AI SEO, GEO or AI visibility offer.
- Strength in links, authority or technical SEO.
- Fit for London businesses.
Entries two to ten are based on how each agency describes its own services in public. For how this site scores the AI models behind this kind of work, see Goldie Bench.
Best AI SEO Agency London: The 2026 Top 10
Here is the ranked list. Number one is the deep entry, and the rest are kept short and factual. If location does not matter to you, the global version is our best AI SEO agency ranking. One note before you start, check each agency's current services before you hire — offers change.
1. Goldie Agency
Goldie Agency is Julian Goldie's own agency, and it takes the top spot because the proof is public. Julian describes it as a 7-figure SEO agency with a team of 50, built from the ground up, with link building as the specialism. He has 10+ years in SEO, wrote the best-selling book SEO Link Building Mastery, and holds a 100% job success score on Upwork.
The delivery model is AI-first SEO. AI agents draft and publish, and humans own strategy, quality and links. The work targets AI answers in ChatGPT, Perplexity and AI Overviews as well as Google.
The receipts are his own published results, and you can find each one by video title.

2. Builtvisible
Builtvisible is a London-based independent agency. It is known for an engineering-grade approach to technical SEO and for data science applied to search. That matters for AI search, because answer engines can only cite pages they can crawl, parse and trust. If your site is large or technically complicated, this is the kind of team to speak to first. Best for: London brands that need technical depth ahead of content volume.
3. Novos
Novos is a London-based ecommerce SEO agency. It pairs technical optimisation with digital PR, which covers the two things an online store needs most, a clean site and coverage that earns authority. Authority is also what AI answer engines lean on when they choose brands to mention. Best for: London ecommerce brands that want technical work and digital PR under one roof.
4. Found
Found is London-based and runs a dedicated AI SEO service line under its "Everysearch" banner. It also tracks AI visibility with its own platform, Luminr. An agency that built its own tracking platform is treating AI search as a channel you can measure, which is the right instinct. Best for: London businesses that want a named AI SEO service with AI visibility tracking built in.
5. Roar Digital
Roar Digital is London-based and describes itself as one of the UK's first agencies to offer generative engine optimisation (GEO) as a dedicated service. That is its own description, so ask how the service runs in practice when you speak to the team. A dedicated GEO offer suits brands whose main goal is being named inside AI answers. Best for: London businesses that want GEO as a standalone service. For more options, see our best GEO agency list.

6. Charle
Charle is a London agency focused on ecommerce brands. It works on visibility across Google AI Overviews, ChatGPT and Perplexity, so the brief covers the main places shoppers now ask for product recommendations. That focus makes it an easy fit if you sell online and want one team thinking about your store and AI answers together. Best for: London ecommerce brands that want AI-answer visibility.
7. Passion Digital
Passion Digital is a London digital agency with an AI-first approach to SEO campaigns. It is a digital agency, not an SEO-only shop, so it is worth a look if you want SEO handled by a team with a wider digital view. Ask what AI-first means in their day-to-day process, because the term covers a lot of ground. Best for: London businesses that want AI-first SEO from a digital agency.
8. ClickSlice
ClickSlice is a London SEO agency that has expanded into AI visibility, GEO and AEO. That path, from classic SEO into AI search, is the same one most London businesses are on themselves. It is worth asking how the two sides are joined up inside a single campaign. Best for: London businesses that want traditional SEO and AI visibility from the same agency.
9. Brainlabs
Brainlabs is a London-founded performance marketing agency with a large SEO practice. The performance marketing background makes it a natural shortlist name for brands that want SEO planned as part of a wider performance set-up. Ask how the SEO practice approaches AI search for a business like yours. Best for: London brands that want SEO inside a performance marketing agency.
10. Re:signal
Re:signal is a London SEO and content agency. Content is still the raw material AI answer engines quote, so an agency that treats SEO and content as one job fits how search works now. The facts we can stand behind here are short, so the entry is short too. Best for: London businesses that want SEO and content from one specialist agency.

How to Choose and What It Costs
Pick the agency that matches your problem, not the one with the nicest office.
- Name the goal. Is it more Google traffic, more mentions in AI answers, or both?
- Ask for proof. Look for results the agency has published and that you can inspect.
- Ask who does the work. Find out what AI handles and what people own.
- Ask how AI visibility is reported. If nobody tracks it, nobody is managing it.
On cost, there is no single London price. It depends on the size of your site, how competitive your market is and how much work is in scope. We are not quoting other agencies' fees, because they change.
Goldie Agency is custom-quoted too. There is no price list, and the move is to Book a free SEO strategy session so the quote fits your site. If you only need classic search work, our SEO agency UK page covers that side.
