The best LLM optimization services, scored on impact, are citation building and brand consensus, and the provider that wins my verdict for running them is Goldie Agency, which is my own agency, so that disclosure comes first.
LLM optimisation, or LLMO, is the work of getting a brand named, described accurately and cited when people ask ChatGPT, Claude, Gemini or Perplexity for answers.
This is the reference version, so I've scored the six services that make up LLMO and compared seven providers on which services each one lists on its own site, checked on 18 October 2026.
The six third-party providers are Kalicube, Animalz, Schema App, Profound, Peec AI and Otterly.ai.

What LLM Optimization Services Are
A large language model is the engine inside tools like ChatGPT, Claude, Gemini and Copilot.
LLM optimization services are the paid jobs that shape what those models find, remember and say about a brand.
Some work on live search, where the tool reads the web and cites pages, and some work on model memory, where the model repeats what it learned from many sites.
The field sits next to GEO, which comes from the paper GEO: Generative Engine Optimization by Pranjal Aggarwal and colleagues, published at KDD 2024.
That paper reported visibility gains of up to 40% in generative engine responses in its own experiments, with results that varied by domain.

The 6 Services Scored On Impact
I scored each service out of five for impact, based on my own testing and on what the official docs say.
| Service | Impact | Why I scored it this way |
|---|---|---|
| Citation building and digital PR | 5/5 | My session page says AI platforms look for consistent signals across trusted third-party sites |
| Entity and brand consensus | 5/5 | A model can't recommend you correctly if the web disagrees about who you are |
| Answer-shaped content | 4/5 | Clear answers backed by real proof are easy to cite, but only once you're trusted |
| AI visibility tracking | 4/5 | It doesn't move answers by itself, but without it you can't see anything change |
| Technical and crawler access | 3/5 | It's essential but quick, and most sites only need a short check |
| Structured data | 2/5 | Google says no special schema is needed for AI Overviews or AI Mode, so it's clarity rather than a lever |
The scores are my judgement, and your mix will shift if you run thousands of pages or sell in a market with few trusted sources.

"Yes" means the provider's own page lists that service, and "Not listed" means I didn't see it there, which doesn't mean the provider can't do it.

Provider-By-Provider Reference
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 session page lists a custom visibility plan, an AI visibility roadmap, a strategy built around your brand, a competitor gap analysis and a plan for traffic, mentions and leads.
In my GEO examples video, Google's AI Overview for "best HARO agency" lists five suppliers and links Goldie Agency first.
Verdict: It covers the two highest-impact services together, and you should weigh my bias.
2. Kalicube
Kalicube says your brand is what Google and AI say it is, and it offers Knowledge Panel work, AI visibility, reputation fixes and consulting with founder Jason Barnard.
Verdict: It's the specialist I'd pick when AI tools describe a brand wrongly.
3. Animalz
Animalz lists an AI visibility audit, an AI search strategy, micro content refreshes, new content, citation outreach, Reddit engagement and reporting.
Verdict: It's the broadest third-party service on this list.
4. Schema App
Schema App builds what it calls a content knowledge graph so AI understands your business as you define it.
Verdict: It's the pick for large sites that need structured data governed properly.
5. Profound
Profound tracks answer engines including ChatGPT, Perplexity, Claude, Gemini, Copilot, DeepSeek and Google AI Overviews, and adds an AI marketer that drafts work for approval.
Verdict: It's the most ambitious tracking platform here, aimed at larger teams.
6. Peec AI
Peec AI tracks visibility, position and sentiment, and it connects to Claude, Cursor and n8n through MCP and an API.
Verdict: It's a strong pick for teams that want to pipe AI visibility data into their own workflows.
7. Otterly.ai
Otterly.ai monitors ChatGPT, Perplexity, AI Overviews, AI Mode, Gemini and Copilot, and offers prompt research, free GEO tools and a free trial.
Verdict: It's the easiest tracker on this list to try before you commit.

My Own Evidence, Labelled As Mine
In my GEO examples video, Google's AI Overview for "best geo expert" names me first and cites several of my 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.
My method is what I call the answer engine, which is be the source, be everywhere and be first.
Those are my results on my sites, so read them as evidence the approach can work and not as a forecast for yours.

Services Or A Full Agency?
| Route | Best when | Watch out for |
|---|---|---|
| Buy individual services | You have one or two clear gaps | Someone still has to join the pieces up |
| Hire a full LLMO agency | You want one team to own the whole job | You'll need your own baseline to check its reports |
| Run it with AI agents | You have time and a clear process | Mistakes go live unless a person reviews them |
If you'd rather hire one team, my best LLM optimization agency comparison scores full-service agencies instead, and my best GEO agency list covers a different set.
What No LLMO Service Can Promise
No service can promise a mention, a position in the answer or a date it will happen.
No service controls how ChatGPT, Claude, Gemini or Perplexity choose sources, and none of their makers publishes a formula.
That includes me and Goldie Agency.
Final Verdict On The Best LLM Optimization Services
Citation building and brand consensus are the highest-impact services, and Goldie Agency wins my verdict for running them, with my bias disclosed.
Kalicube is the specialist for brand consensus, Animalz is the broadest third-party service, and Peec AI or Otterly.ai are where I'd start for tracking.
Buy the high-impact services first, track with a baseline and never pay for a guarantee.
