Best Generative Engine Optimization Agency: Seven Picks By Region, And How The Models Behind AI Answers Score

The best generative engine optimization agency on my list is Goldie Agency, and I'm telling you upfront that it's my own agency so you can weigh my bias.

A GEO agency is a team that works to get your brand used, cited and recommended inside the answers that AI tools write, such as ChatGPT, Perplexity, Gemini and Google's AI Overviews.

I've sorted my other six picks by region and size, which are SALT.agency, Power Digital, StudioHawk, Delante, ClickSlice and Boostability, and I checked each one on its own site 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 AI visibility plan.

In this post I'll explain what a GEO agency does, why your market changes the hire and how to choose one.

Near the end, I'll show you how the models from the US and Chinese labs behind AI answers score on this leaderboard, and what that does and doesn't tell you.

Here's my full ranking of the seven GEO agencies in one table, with my own agency at number one.

What is a generative engine optimization agency?

A GEO agency improves how often generative AI tools use your content and name your brand in their answers.

The term comes from a research paper called GEO: Generative Engine Optimization by Pranjal Aggarwal and colleagues, first posted on arXiv on 16 November 2023 and published at KDD 2024.

The paper reported that GEO methods can boost visibility by up to 40% in generative engine responses.

It found that citing sources, adding quotations and adding statistics were the strongest methods, while keyword stuffing gave little to no improvement.

It also found that the best method varies by domain, which is one reason the right agency depends on your market.

The two overlap heavily, and Google's AI features guide says AI Overviews and AI Mode have no additional requirements beyond normal SEO.

Why your region changes which GEO agency you should hire

Buyers ask AI tools in their own language about their own local options.

The answers draw on local publications, local review sites and local comparison pages, so the sources that matter in Leeds aren't the ones that matter in Sydney.

An agency that knows those sources and tests your questions in your buyers' language will find gaps a distant team can miss.

Size matters too, because an enterprise brand needs board-level reporting while a small business needs a plan it can afford to keep running.

The 7 best generative engine optimization agencies in 2026

I avoided the agencies already compared in my best GEO agency and AI SEO optimization 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 in Bangkok.

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

The session page says AI platforms look for consistent signals across the wider web, so the work is expert bylines, independent reviews, industry comparisons and research-led coverage.

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

2. SALT.agency

SALT.agency's page says its monitoring feeds a prioritised action plan, and it also covers product data for AI shopping agents.

3. Power Digital

Power Digital's GEO page names ChatGPT, Google AI Overviews, Perplexity, Claude, Gemini and Copilot as the platforms it targets.

4. StudioHawk

StudioHawk's page says it monitors visibility using platform data, manual checks and entity analysis.

5. Delante

Delante's page says its audit ends with technical, content and off-site recommendations.

6. ClickSlice

ClickSlice's page says it tracks commercial prompts, category questions, comparison searches and solution-led queries.

7. Boostability

Boostability's page says it works with small businesses, agencies and resellers, and it offers a free site analysis.

I haven't hired these six agencies, so I'm describing what each one says about itself.

I haven't listed prices, because agencies quote after a call and I won't guess.

How to hire a GEO agency for each market

Use this table on every sales call, whichever country the agency is in.

OpenAI's crawler page recommends allowing OAI-SearchBot, and Perplexity's crawler page recommends allowing PerplexityBot, on every domain you run.

Google's guidance on generative AI content says "It is critical to manually factcheck and review all AI-generated content for accuracy and trustworthiness before publishing."

If you'd like a second opinion on a proposal you've already got, book a free SEO strategy session and bring it with you.

Should you hire a local GEO agency or a global one?

There isn't one right answer, so match the choice to how many markets you sell in.

If you pick a global agency, ask it to show you one baseline in a language other than English before you sign.

If you pick several local agencies, give them all the same question format, so you can compare their results on equal terms.

What GEO looks like on my own sites

In my GEO examples video, Google's AI Overview for "best geo expert" names me first, and several of my pages appear in its sources.

For "best HARO agency", the AI Overview lists five suppliers and links Goldie Agency first.

One of my sites went from zero to about 1,300 Google clicks a day, and on one day it got over 9,600 impressions inside Google's AI features.

Those are my results on my own screens, and I also had a site that flopped, so treat them as proof of the method rather than a promise.

Nobody can guarantee what a model says

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

None of the companies behind ChatGPT, Perplexity, Gemini or Claude publishes a formula for which brands get recommended.

Which models sit behind AI answers in different markets, 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 which brands an AI recommends, and it doesn't measure GEO results.

A GEO agency doesn't ship its own model, and none of the agencies above has a model on the board.

The AI tools your buyers use are built on models from US labs and Chinese labs, so here's how those makers' models score on their live pages today.

Claude Opus 5 leads this group at 8.27, with GPT-5.6 Sol at 8.16 and Alibaba's Qwen 3.8 close behind at 8.10.

Kimi K3 averages 7.89 and GLM-5.2 averages 7.77, so the Chinese labs are right in the mix.

Grok 4.7 averages 7.15 and Gemini 3.6 Flash averages 7.08.

Delante's audit names DeepSeek as one of the AI tools it checks, and DeepSeek V4 Flash is on the board but currently unranked, so I can't give you a score for it.

Perplexity has no model on GoldieBench either, so I can't score it.

The board can't tell you which exact model a consumer app runs at any moment, because the makers change that themselves.

What the model scores mean when you hire a GEO agency

The scores matter when an agency uses AI to draft the work, such as answer-first pages in several languages.

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 more than the model itself, especially in a language your team doesn't read.

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

So ask every agency who checks the drafts in each language, and not just which model it uses.
