Best LLM Optimization Agency: Seven Picks And A Quick Start For Hiring One While Your Agent OS Keeps Score
The best LLM optimization agency on my list is Goldie Agency, and since it's my own agency, I'm flagging that bias in the first line.
LLM optimisation, or LLMO, is the work of getting your brand named, described correctly and cited when people ask ChatGPT, Claude, Gemini or Perplexity for a recommendation.
My other six picks are LinkGraph, Discovered Labs, Momentic, Dreikon, Embryo and Brafton, all checked on their own sites on 18 October 2026.
This quick start shows you how to hire one in five steps, and how your Agent OS keeps its own dated record so you never take a report on trust.
If you want help from day one, book a free SEO strategy session and get a custom AI visibility game plan.
Here's my full shortlist in one table, with my own agency at number one.
| Rank | Agency | Best for |
|---|---|---|
| 1 | Goldie Agency (my agency) | One team for AI visibility, coverage and links. |
| 2 | LinkGraph | A packaged LLM visibility plan. |
| 3 | Discovered Labs | B2B SaaS with tracking built in. |
| 4 | Momentic | AI search plus agent readiness. |
| 5 | Dreikon | German-speaking markets. |
| 6 | Embryo | UK brands that want GEO next to SEO. |
| 7 | Brafton | Content-heavy brands. |
I read every third-party page on 18 October 2026, and each one advertises LLM, GEO, AEO or AI search work today.
I skipped the agencies from my best GEO agency and AI SEO optimization agency guides, so this list adds new names.
I haven't hired the six third-party agencies, so I'm describing what each one says about itself.
I haven't listed prices either, because agencies quote after a call and I won't guess.
What the best LLM optimization agency actually does
LLM optimisation, or LLMO, is the work of shaping what large language models find, remember 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 for a recommendation, it usually names only a handful of businesses, so LLMO is about being one of them and being described correctly.
There are two routes into an answer, and a good agency works on both.
| Route | How a model ends up naming you | What your agents can check |
|---|---|---|
| Live search | The tool searches the web, reads pages and cites some of them. | Whether your pages are cited, and whether robots.txt lets the AI crawlers in. |
| Model memory | The model repeats what it learned from the wider web during training. | What the tool says about you with web search switched off, where the tool allows it. |
The label sits right next to GEO, which comes from the paper GEO: Generative Engine Optimization by Pranjal Aggarwal and colleagues, and AEO, which targets direct answers.
Most agencies use the three labels interchangeably, so judge the work rather than the acronym.
Quick start: hire an LLM optimization agency in five steps
This is the fastest safe route from a cold start to a signed first phase.
- First, write 20 prompts a real buyer would type into an AI tool before choosing a business like yours.
- Second, let your Agent OS ask each prompt in ChatGPT, Claude, Gemini, Perplexity and Google's AI Mode, and save the answers with dates, brands named and sources cited.
- Third, have an agent check robots.txt, because OpenAI's crawler page recommends allowing OAI-SearchBot and Perplexity's crawler page recommends allowing PerplexityBot.
- Fourth, shortlist three agencies from the table, book their free first step and take your baseline to every call.
- Fifth, sign a 90-day first phase with deliverables you can inspect, and let your agents re-ask the prompts at the end.

Number one: Goldie Agency
Goldie Agency is the SEO and link building agency I started on my own, and it now has 70+ people in Bangkok.I rank it first because I know exactly how the work is done, and you should weigh that as my bias.
The strategy session page says the agency 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, such as trusted publications, expert articles, independent reviews and comparisons.
The agency site also lists link building with manual outreach and no PBNs, a Complete Site Audit and AI Automation.
AI runs around 80% of our internal operations through the same kind of Agent OS setup I teach on this site.
In my GEO examples video, I show Google's AI Overview for "best HARO agency" listing five suppliers and linking Goldie Agency first.
Paid work is scoped after the session, so I won't quote a price here.
The other six, in one line each
- LinkGraph's AI visibility page lists an LLM visibility audit, brand entity optimisation, content, link building and digital PR, press release syndication, local citations and AI visibility tracking.
- Discovered Labs calls itself an AEO and GEO agency for B2B companies and lists its own AI Visibility Tracker.
- Momentic lists AI search across ChatGPT, Gemini, Copilot, Claude and Perplexity, plus AXO for AI agents that act on your site.
- Dreikon's LLMO page says it structures content so AI systems recognise it, classify it and use it in their answers.
- Embryo's GEO page lists brand entity building, structured data, multi-platform tracking and digital PR from Manchester.
- Brafton's GEO page lists content optimisation for AI, sentiment analysis and tracking of AI citation presence.
How an LLM optimization agency fits an Agent OS workflow
My Agent OS runs a crew of AI agents under one shared memory, and that makes hiring an LLMO agency much safer.
The reason is simple, because you stop relying on the agency's report as your only source of truth.
Your agents keep the receipts, and the agency does the work you can't do alone.
| LLMO job | Your Agent OS handles it | The agency handles it | You handle it |
|---|---|---|---|
| Prompt baseline | An agent asks your 20 buyer prompts in ChatGPT, Claude, Gemini, Perplexity and Google every week and saves the answers. | The agency reads the trend and picks priorities. | You choose the prompts your buyers really use. |
| Brand fact file | An agent keeps one fact file of your name, services, location and proof in shared memory. | The agency fixes the places online that disagree with it. | You approve every fact. |
| Mentions | An agent logs every byline, review and comparison the agency wins, with links and dates. | The agency earns the coverage. | You give interviews and approve quotes. |
| Answer pages | An agent drafts pages that open with a direct answer and carry your real proof. | The agency edits for angle and quality. | You fact-check, because Google says AI content needs human review. |
| Crawler access | An agent checks robots.txt for OAI-SearchBot and PerplexityBot. | The agency fixes what the agent flags. | You sign off changes to the live site. |
The shared memory is what makes this work over months.
Every prompt, every answer and every new mention lands in one place, so any agent can compare this month with last month.
You can check an agency's claims against your own dated records without arguing about screenshots.

The 90-day first phase, with your agents keeping score
| Weeks | What the agency delivers | What your agents log |
|---|---|---|
| 1 to 2 | Agreed prompts and a reviewed baseline | The first dated answers, with and without web search |
| 3 to 4 | A brand fact audit and a list of target sources | The approved fact file and the source list |
| 5 to 8 | Rewritten key pages with direct answers and real proof | Each page's publish date and target prompts |
| 5 to 12 | Mentions such as bylines, reviews and comparisons | Every new mention with its link and date |
| 12 | A review against the baseline | The same prompts re-asked and compared |
Ask an agent to pull that report every week, because it's free measurement you already own.
My own answer engine, and what it shows
I call my system the answer engine, and it has 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, because an AI can't write about a test only you ran.
Being everywhere means several sites and platforms say the same thing about you, so the model sees consensus.
Being first means publishing within 24 hours when a new topic appears in your niche.
In my GEO examples video, I 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 one day.
Those are my results on my sites, so treat them as proof the approach can work and not as a forecast for yours.
Google's guidance on using generative AI content says AI-written pages should be fact-checked and reviewed by people before publishing, so keep a human review step in every agent workflow.
Nobody can guarantee what a model says
I want to be honest about this before you spend anything.
Nobody can guarantee what a model says, and that includes me and Goldie Agency.
None of the companies behind ChatGPT, Claude, Gemini or Perplexity publishes a formula for which brands get recommended.
An agency can improve the footprint those models read and the honesty of its reporting.
An agency can't control the answer, the timing or the revenue that follows, so treat any guarantee as a warning sign.
Red flags to walk away from
- Walk away from any agency that guarantees a mention in ChatGPT, Claude, Gemini or Google's AI.
- Walk away from anyone who sells special schema or an AI text file 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.
