The best LLM optimization agency for most businesses on my list is Goldie Agency, and I'm telling you straight away that it's my own agency, so weigh my bias.
LLM optimisation means getting your business named and described correctly when customers ask AI tools like ChatGPT, Claude, Gemini and Perplexity who they should buy from.
The right agency for you depends on what you sell and who you sell to, so this post matches six third-party agencies to real kinds of business.
Those six are LinkGraph, Discovered Labs, Momentic, Dreikon, Embryo and Brafton, and I checked each one on its own site on 18 October 2026.
If you'd like my team's view of your business first, book a free SEO strategy session and see where AI tools mention you today.

Why Businesses Are Paying For LLM Optimisation Now
Your customers used to type a question into Google and scroll a page of ten links.
Now many of them ask an AI tool and read a short answer that names just a few businesses.
In my GEO examples video I put it simply, because if the answer only names one to three businesses, there's no room for whoever comes seventh.
That's a real business problem, because being left out of the answer means you're left out of the shortlist.
LLM optimisation is the work of getting your business onto that shortlist and making sure the AI describes you correctly.

What An LLM Optimization Agency Does For A Business
| Job | What it means in plain English | Why a business owner should care |
|---|---|---|
| Baseline | The agency asks the questions your buyers ask and saves what each AI tool says | You find out whether you're being recommended today |
| Brand facts | The agency makes your name, services and proof match everywhere online | AI tools stop mixing you up or getting details wrong |
| Mentions | The agency earns reviews, articles and comparisons on sites the AI trusts | Models lean on what other sites say about you |
| Answer pages | The agency rewrites key pages so they answer buyer questions directly | AI tools can lift and cite a clear answer |
| Tracking | The agency re-asks the questions and reports the raw answers | You can see whether your money is working |
How I Ranked These Agencies
I judged each agency on what its own site shows today, because that's what I could check.
I looked for a live LLM, GEO or AI search service, both on-site and off-site work, a way to measure AI answers, and a clear sense of who the agency serves.
I skipped agencies I've already covered in my best GEO agency and AI SEO optimization agency posts, so these are fresh names.
I haven't hired the six third-party agencies, and I haven't listed prices, because they quote after a call.
The 7 Best LLM Optimization Agencies For Business
1. Goldie Agency
Goldie Agency is the SEO and link building agency I started on my own, and it has grown to 70+ people in Bangkok.
The session page says it helps brands get found, cited and recommended by Google and AI across Google, AI Overviews, ChatGPT, Perplexity and Gemini.
It says AI platforms look for consistent signals across the wider web, so the work focuses on expert bylines, independent reviews, comparisons and research-led coverage.
The agency site also lists link building with manual outreach and no PBNs, plus a Complete Site Audit.
In my GEO examples video I show Google's AI Overview for "best HARO agency" listing five suppliers and linking Goldie Agency first, and I show it ranking first organically too.
Best for: I'd pick it for service businesses and brands that want AI visibility, content and links handled by one team.
2. LinkGraph
LinkGraph says on its AI visibility page that it helps businesses become the go-to answer when AI models respond to real questions.
Its LLM visibility plan lists an audit, brand entity optimisation, content, link building and digital PR, press release syndication, local citation building and AI visibility tracking.
Best for: I'd pick it for owners who want to see every deliverable listed before they commit.
3. Discovered Labs
Discovered Labs calls itself an AEO and GEO agency for B2B companies.
Its site lists answer engine optimisation, Reddit marketing, SEO and link building, plus its own AI Visibility Tracker.
Best for: I'd pick it for B2B SaaS companies whose buyers compare tools inside AI chats.
4. Momentic
Momentic says it works across your website, content, reviews, profiles, social and video so your brand gets found and recommended when customers search or ask AI.
It also lists AXO, which it describes as helping AI agents take action on your site.
Best for: I'd pick it for marketing teams that want to be ready for AI agents as well as AI answers.
5. Dreikon
Dreikon is a German agency with a dedicated LLMO page.
The page says mentions in relevant contexts are picked up by AI as a signal, and it recommends specialist portals, interviews and white papers.
Best for: I'd pick it for businesses selling into German-speaking markets.
6. Embryo
Embryo is a Manchester-based agency with a GEO and AEO services page.
Its page lists content for AI visibility, AI visibility auditing, brand entity building, structured data, multi-platform tracking and digital PR.
Best for: I'd pick it for UK businesses that want GEO run next to their classic SEO.
7. Brafton
Brafton is a content marketing agency with a GEO services page.
The page lists content optimisation for AI, sentiment analysis of how AI tools portray your brand and tracking of AI citation presence.
Best for: I'd pick it for content-led brands that need a steady flow of high-quality pages.

Which LLM Optimization Agency Fits Your Business?
| Your business | What usually holds you back in AI answers | Agency I'd look at first |
|---|---|---|
| A local service business | Too few reviews and mentions outside your own site | Goldie Agency or Embryo |
| A B2B SaaS company | You're missing from the comparison pages AI tools cite | Discovered Labs |
| An ecommerce brand | AI tools describe your products vaguely or not at all | Momentic or Brafton |
| A German-speaking exporter | Few trusted mentions in your market's language | Dreikon |
| A business that wants a fixed package | You don't know what to ask for | LinkGraph |
| A brand with a big content team | Pages are long but don't answer questions directly | Brafton |
Use Case 1: The Plumber Who Isn't In The Answer
Picture a plumber whose customers ask ChatGPT for "the best emergency plumber near me".
The answer leans on review sites, local directories and local news, so the plumber's own website is only a small part of the picture.
An agency would fix the plumber's facts across every listing and earn local mentions the AI can read.
In my video I make the point that this works for normal service businesses like dentists, plumbers and accountants, not just tech companies.
Use Case 2: The SaaS Tool Left Out Of Comparisons
Picture a software company whose buyers ask Claude to compare the top five tools in its category.
The answer pulls from review platforms and comparison articles, so a feature page alone won't get the company named.
An agency like Discovered Labs would target those comparison sources and track whether the company starts appearing.
Use Case 3: The Ecommerce Brand With Thin Product Facts
Picture an online shop whose products the AI describes in one vague line, if at all.
An agency would make product facts clear and consistent and earn reviews and roundups on trusted sites.
Use Case 4: The Agency Owner Who Wants To Resell It
Some of you run marketing agencies and want to offer LLM optimisation to clients.
The honest move is to learn the work first, then decide which parts you deliver yourself and which parts you outsource.
If you want to explore outsourcing to my team, the free strategy session is the place to ask whether it's a fit.

How To Judge The Return Honestly
LLM optimisation is new, so agree how you'll judge it before you spend anything.
| What to track | How to track it | Why it matters |
|---|---|---|
| Mentions | The same buyer prompts re-asked every month | It shows whether AI tools name you more often |
| Accuracy | Whether each AI describes you correctly | A wrong description can quietly cost you sales |
| Citations | The sources each answer links to | It shows whether your pages are being used |
| AI search traffic | Search Console's "Web" search type, which Google says includes AI Overviews and AI Mode | It's free data you already own |
| Enquiries and sales | Your CRM or booking system | It's the number that pays the bills |
My own results are a guide to what's possible, not a promise, and in my video I show one of my sites going from zero to about 1,300 Google clicks a day.
On a single day that site also got over 9,600 impressions inside Google's AI features.
I'd still never judge an agency on mentions alone, because a mention that doesn't lead to an enquiry is only half the job.

The Brief To Send Any LLM Optimization Agency
| Section | What to write |
|---|---|
| Who you are | One paragraph on what you sell, who you sell to and where |
| Buyer prompts | Ten questions your buyers ask an AI tool before choosing |
| Your baseline | What ChatGPT, Claude, Gemini, Perplexity and Google say today, with dates |
| Competitors | The businesses AI tools name instead of you |
| Proof | Your real case studies, reviews and results |
| Goal | The enquiries or sales you want, not just mentions |
Send the same brief to every agency, and the differences in their answers will tell you who to hire.
Be Honest About What LLM Optimisation Can Do
Nobody can guarantee what a model says, and that includes me and Goldie Agency.
An agency can improve the footprint AI tools read about you, and it can't control the final answer.
Google's guidance on using generative AI content also says AI-written content should be fact-checked and reviewed by people before it goes live.
So if an agency uses AI to write for you, ask to see its human review step.
