LLM SEO Services Agency: What It Delivers, When It's Worth It, And The AI Models Behind The Work

An LLM SEO services agency is a team you hire to get your brand named in the answers that ChatGPT, Claude, Gemini and Google's AI write, while keeping your classic rankings strong, and the first one I'd call is my own, Goldie Agency, so please weigh that bias.

Whether it's worth it depends on what the agency actually delivers each month, so that's what this post explains first.

My third-party shortlist is Ten Speed, Skale, Reboot Online, Hallam and Wpromote, and I read each one's own service page on 18 October 2026.

If you want my team to look at your brand first, you can book a free SEO strategy session and get a custom game plan for Google and AI search.

Near the end, I'll show you how the AI models an agency might use to draft and analyse the work score on this leaderboard, and what that does and doesn't tell you.

Here's my shortlist of six LLM SEO services agencies in one table, with my own agency at number one.

What is an LLM SEO services agency?

An LLM SEO services agency sells ongoing work that helps large language models find, trust and name your brand.

The LLM is the engine inside tools like ChatGPT, Claude and Gemini.

In my GEO examples video, I explain why it matters, because ten blue links let even position seven pick up clicks, while an AI answer might only name one to three businesses.

AI tools read the pages that already rank and repeat what they agree on, so the services cover AI answers and classic SEO together.

Google's AI features guide says AI Overviews and AI Mode have no additional requirements beyond normal SEO, which is why classic SEO stays in any honest plan.

What an LLM SEO services agency delivers, month by month

This is the test of whether an agency is worth it, because you should be able to point at something new every month.

Ten Speed's page, for example, says its onboarding takes about three to four weeks and that visibility and citations build over three to six months or more.

So if a proposal promises big AI visibility changes in the first fortnight, I'd be sceptical.

On 1 October 2026, Google updated its guidance on using generative AI content, and it says it's critical to manually fact-check and review AI-generated content before publishing.

So every content deliverable should come with a named human reviewer.

How LLM SEO services agencies charge

I won't list prices, because agencies quote after a call and the numbers depend on scope.

When an LLM SEO services agency is worth it, and when it isn't

• It's usually worth it when your buyers already ask AI tools for recommendations in your category.
• It's usually worth it when you have real proof, such as case studies and results, that nobody has turned into pages yet.
• It's usually worth it when you don't have the people to earn third-party mentions yourself.
• It probably isn't worth it yet when your site has basic technical problems that a cheaper SEO fix would solve first.
• It isn't worth it when the proposal has no monthly deliverables you can inspect.
• It's never worth it when the proposal guarantees that an AI tool will recommend you.

What to prepare before you hire one

The agencies that are worth it get better results from clients who arrive prepared, so here's the pack I'd bring to the first call.

• I'd bring twenty questions my buyers actually ask an AI tool before they choose a supplier.
• I'd bring a dated record of what ChatGPT, Claude, Gemini and Google say for each of those questions today.
• I'd bring three months of queries, clicks and positions from Search Console, because Google counts AI Overviews and AI Mode traffic inside the "Web" search type.
• I'd bring every case study, test and result I can prove, because that's the raw material an AI tool can't copy.
• I'd bring one short fact sheet with my name, services, locations and proof.

I'd also check my robots.txt first, because OpenAI recommends allowing OAI-SearchBot and Perplexity recommends allowing PerplexityBot.

An agency that reads this pack and asks sharp questions about it is usually worth a second call.

The 6 LLM SEO services agencies on my shortlist

I avoided the agencies already compared in my best LLM SEO agency and best GEO agency posts, so these are fresh options.

1. Goldie Agency

Goldie Agency is the SEO and link building agency I started on my own, and it now has 70+ people.

It's my company, so this is the most biased entry on the page.

The site lists link building with manual outreach and no PBNs, a Complete Site Audit and AI Automation.

The strategy session page says AI platforms look for consistent signals across the wider web, such as trusted publications, expert articles, independent reviews and comparisons.

In my GEO examples video, Google's AI Overview for "best HARO agency" lists five suppliers and links Goldie Agency first, which is my own result and not a promise for yours.

2. Ten Speed

Ten Speed describes itself as an answer engine optimisation agency for B2B companies, with a dedicated strategist, a quarterly content and technical roadmap and monthly reporting.

3. Skale

Skale starts with your North Star Metric and a 12-month growth model, then gives you a 90-day execution plan with weekly updates.

4. Reboot Online

Reboot Online is a London GEO agency that says it uses controlled testing and benchmarks your AI citation share against competitors.

5. Hallam

Hallam tracks AI visibility with its Share of LLM framework and connects AI referrals to pipeline with custom GA4 tracking.

6. Wpromote

Wpromote combines organic AI search with paid search and AI ad placements, and tracks your brand across about 300 prompts and 15 topics.

I haven't hired these five agencies, so I'm describing what each one says about itself, and I haven't listed prices or client results.

Why I believe the services are worth it when they're done properly

I run these services on my own sites, so this is what I base my view on.

In my GEO examples video, I show Google's AI Overview for "best geo expert" naming me first, with several of my pages in its sources.

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 figures come from my own screens, and they explain my view rather than promise anything for you.

My system, which I call the answer engine, is to be the source, be everywhere and be first.

Nobody can guarantee what a model says

Nobody can guarantee what a model says, and that includes me and Goldie Agency.

An agency controls the footprint a model reads and the honesty of its reporting, and it doesn't control the answer.

• Walk away from any agency that guarantees ChatGPT, Claude or Google's AI will recommend you.
• Walk away from any retainer that doesn't name its monthly deliverables.
• Walk away from anyone who sells special schema or an AI text file as the secret, because Google says neither is needed for its AI features.

Which AI models might an LLM SEO services agency use, and how do they score on GoldieBench?

Now for the GoldieBench part, and I need to be clear about what it measures.

GoldieBench scores models on one-shot builds such as landing pages, apps, games and visuals, on a 0 to 10 scale.

It doesn't measure SEO results, and it doesn't measure which brands an AI recommends.

An LLM SEO services agency doesn't ship its own model, and none of the agencies above has a model on the board.

Many agencies use models to draft pages, summarise baselines and build reports, so this is how some widely used models score on their live pages today.

Claude Opus 5 leads this group at 8.27, with Qwen 3.8 at 8.10 and MiniMax M3 at 7.97.

Kimi K3 averages 7.89, GLM-5.2 averages 7.77 and Claude Sonnet 5 averages 7.01.

I can't tell you which models any agency on my shortlist uses, because their pages don't say, so ask them directly.

What the model scores mean for an LLM SEO services agency

A model that follows a detailed brief well first time leaves fewer mistakes for a human editor to catch.

Even so, the system around the model matters far more than the model itself.

A cheaper model with a clear brief, an approved fact file and a human editor can produce very good pages.

A top model with no fact-checking still produces confident mistakes, and those are the last thing you want an AI tool to quote about you.

So ask every agency what happens before and after the model writes, and judge the workflow rather than the model name.
