The best LLM optimization agency on my list is Goldie Agency, and because it's my own agency, I'm flagging that bias in the very first line.
LLM optimisation, often shortened to LLMO, is the work of getting your brand named, described correctly and cited when people ask large language model tools like ChatGPT, Claude, Gemini and Perplexity for a recommendation.
My six third-party picks are LinkGraph, Discovered Labs, Momentic, Dreikon, Embryo and Brafton, and I checked that each one advertises LLM, GEO or AI search work on its own site on 18 October 2026.
This is the operator version, so after the ranking I'll show you exactly how to test an agency and run your first 90 days with one.
If you'd rather start with a plan from my team, book a free SEO strategy session and get a custom AI visibility game plan.
Here's the full ranking in one table, with my own agency at number one.
| Rank | Agency | Best for |
|---|---|---|
| 1 | Goldie Agency (mine) | One team for AI visibility, content and links |
| 2 | LinkGraph | A packaged LLM visibility plan |
| 3 | Discovered Labs | B2B SaaS that wants tracking built in |
| 4 | Momentic | Brands that want AI search plus agent readiness |
| 5 | Dreikon | Brands selling into German-speaking markets |
| 6 | Embryo | UK brands that want GEO next to classic SEO |
| 7 | Brafton | Content-heavy brands that need volume and quality |
Top 3 Picks At A Glance
- 🥇 Goldie Agency is my pick, it's my own agency, and the first step is a free SEO strategy session.
- 🥈 LinkGraph is my top third-party pick, because its page spells out an LLM visibility plan line by line.
- 🥉 Discovered Labs is my pick for B2B software brands that want their own AI visibility tracker in the deal.
What LLM Optimisation Actually Means
LLM optimisation is the job of shaping what large language models know and say about your brand.
A large language model is the engine inside ChatGPT, Claude, Gemini, Copilot and the rest.
When a buyer asks one of those tools "who's the best accountant in Leeds?" or "which CRM should a startup use?", the model writes a short answer and usually names only a handful of businesses.
LLMO is everything you do so your name is one of them, and so what the model says about you is accurate.
There are two ways a model can end up mentioning you, and a good agency works on both.
| Route | How it works | What the agency works on |
|---|---|---|
| Live search | The tool searches the web, reads pages and cites some of them | Pages that rank, crawler access and answer-shaped content |
| Model memory | The model repeats what it learned from the wider web during training | Consistent brand facts and mentions across many trusted sites |
LLMO Versus GEO Versus AEO
People use three labels for very similar work, so here's how I separate them.
| Label | Stands for | What it puts first |
|---|---|---|
| LLMO | Large language model optimisation | What the model itself knows and says about your brand |
| GEO | Generative engine optimisation | Being cited inside AI-written answers |
| AEO | Answer engine optimisation | Being the direct answer to a question |
GEO comes from a research paper called GEO: Generative Engine Optimization by Pranjal Aggarwal and colleagues, first posted on arXiv in November 2023.
In practice, most agencies use the three labels interchangeably, so judge the work and not the acronym.
If you want the GEO-first version of this list, my best GEO agency ranking covers a completely different set of agencies.

How I Ranked These LLM Optimization Agencies
I ranked each agency on what its own site shows today, because that's what I could check.
| What I checked | Why it matters |
|---|---|
| The site names LLM, GEO, AEO or AI search as a live service | You want a team already doing the work, not one renaming old SEO |
| The site describes both content work and off-site mentions | Models lean on what other sites say about you, not just your own pages |
| The site shows a way to measure AI answers | Without a baseline you can't tell if anything changed |
| The site shows who the agency serves | A B2B SaaS team and a local plumber need very different partners |
I left out every agency I've already compared in my AI SEO optimization agency and best GEO agency posts, so this list gives you new options.
I haven't hired the six third-party agencies, and I haven't listed prices, because agencies quote after a call.
The 7 Best LLM Optimization Agencies In 2026
1. Goldie Agency (My Agency)
Goldie Agency is the SEO and link building agency I started on my own, and it now has 70+ people in Bangkok.

The agency site also lists link building with manual outreach and no PBNs, a Complete Site Audit and AI Automation.
My proof is public, and in my GEO examples video I show Google's AI Overview for "best HARO agency" listing five suppliers and linking Goldie Agency first.
Best for: I'd pick it for brands that want AI visibility, content and links from one team.

How To Hire An LLM Optimization Agency In 6 Steps
This is the operator part, so here's the exact process I'd follow if I were hiring an agency other than my own.
Step 1: Write 20 buyer prompts
Write 20 questions a real buyer would type into an AI tool before choosing a business like yours.
Mix "best X" prompts, comparison prompts and problem prompts, because each one pulls different sources.
Step 2: Test both routes
Ask each prompt in ChatGPT, Claude, Gemini, Perplexity and Google's AI Mode.
Where a tool lets you turn web search off, ask the prompt again without it, because that shows you what the model remembers rather than what it finds.
Save every answer with the date, the brands named and the sources cited.
Step 3: Check crawler access
Open your robots.txt and make sure you aren't blocking the crawlers that power AI search.
OpenAI's crawler page recommends allowing OAI-SearchBot to appear in ChatGPT search results, and Perplexity's crawler page recommends allowing PerplexityBot.
Step 4: Shortlist three agencies
Pick three agencies from the table that match your size, your market and your language.
Book their free first step and take your baseline to every call.
Step 5: Ask for the plan, not the pitch
- Ask which of your 20 prompts they'd target first and why.
- Ask which third-party sites the models already trust in your market.
- Ask how they'll work on both live search and model memory.
- Ask whether you'll see the raw, dated answers in every report.
- Ask what they can't promise.
Step 6: Sign a 90-day first phase
Agree a short first phase with deliverables you can inspect, then re-run your baseline at the end.

What I Do On My Own Sites
I don't just sell this, because I test it on my own brands every week.
In my GEO examples video, I show Google's AI Overview for "best geo expert" naming me first and citing several of my own pages.
I also show one of my sites going from zero to about 1,300 Google clicks a day, with over 9,600 impressions inside Google's AI features on a single day.
Those are my own results on my own sites, and they aren't a promise about yours.
I call my system the answer engine, and it comes down to three moves, which are be the source, be everywhere and be first.
Being the source means every page carries a real test or case study, being everywhere means several trusted sites say the same thing about you, and being first means publishing within 24 hours of a new topic.
Google's guidance on using generative AI content says you should "manually factcheck and review all AI-generated content" before publishing it.
So any agency using AI to write for you should show you its human review step.

Your First 90 Days With An LLM Optimization Agency
| Weeks | What the agency should deliver | What you should do |
|---|---|---|
| 1 to 2 | Agreed prompts and a dated baseline across five AI tools | Give read-only access to Search Console and analytics |
| 3 to 4 | A brand fact audit and a list of target sources | Approve one clean fact file |
| 5 to 8 | Key pages rewritten with direct answers and real proof | Add the experience only you have |
| 5 to 12 | Mentions under way, such as bylines, reviews and comparisons | Give interviews and approve quotes |
| 12 | The same prompts re-asked and compared with the baseline | Decide whether to continue |
Google's AI features guide says AI Overviews and AI Mode traffic is counted inside the "Web" search type in Search Console, so check it next to the agency's report.
Red Flags When Hiring An LLMO Agency
- Walk away from any agency that guarantees ChatGPT, Claude or Gemini will recommend you.
- Walk away from anyone selling an AI text file or special schema as the secret, because Google says neither is needed for AI Overviews or AI Mode.
- Walk away from any plan built on thousands of unreviewed AI pages.
- Walk away from any agency that won't show you raw, dated answers.
Nobody can guarantee what a model says, and that includes me and Goldie Agency.

What is LLM optimisation?
LLM optimisation, or LLMO, is the work of getting your brand named, described correctly and cited when people ask tools like ChatGPT, Claude, Gemini and Perplexity for answers.
Is LLM optimisation the same as GEO and AEO?
They overlap heavily.
GEO focuses on generative engines, AEO on answer engines, and LLMO on the language models themselves, but the day-to-day work is mostly the same.
Can an LLM optimization agency guarantee that ChatGPT will recommend me?
No, because nobody can guarantee what a model says.
A good agency improves what models can read about you and reports the answers honestly.
How do I test an LLM optimization agency before hiring it?
Record your own baseline of AI answers first.
Then ask each agency which prompts it would target, which sources it would earn coverage on and how it would report the raw answers.
