Top Agencies for Getting Your Company Mentioned by ChatGPT and Other AI Assistants

Introduction

If you are asking why ChatGPT never mentions your brand, this article works through four common causes, and an agency works on each one.

This article is written for marketing leaders at B2B SaaS and technology companies who rank fine on Google, have a real product, and still watch AI assistants recommend somebody else when a buyer asks who to hire.

Catalyst (gotcatalyst.com) sells answer engine optimization (AEO), so this is our own blog and not a neutral roundup. We are not going to rank other firms here. What follows is the diagnosis, the criteria a buyer should use to evaluate any agency doing this work, and what Catalyst publishes against those criteria so you can compare.

Key Takeaways

• Strong Google rankings do not guarantee AI citations.
• Entity recognition, buyer-intent pages, cited sources and crawlability are four causes to check.
• Ask any agency for its query set, assistant list and guarantee.
• The free AEO audit returns AI Voice Share in about 60 seconds.

Why ChatGPT Never Mentions Your Brand

Large language models (LLMs) assemble answers from sources they can reach and trust. This article looks at four things that are often missing when your brand is absent from an answer.

The assistant does not recognize you as a distinct company. Catalyst calls this entity authority, and the point it makes on its AEO page is blunt. "Strong Google rankings don't guarantee AI citations." Domain authority and entity authority are different systems.

No page of yours answers the question the buyer actually typed. Catalyst lists "You want to optimize for brand queries, not buyer-intent queries" as a reason a company is not a fit for this work.

You are missing from the sources AI cites. Catalyst sells 8, 12 or 15 placements a month on the sources AI cites, alongside the articles in every Grow tier.

Your pages cannot be read cleanly. Schema markup and structured data are a separate monthly step in Catalyst's delivery.

How to Tell Which of the Four Is Your Problem

Guessing is the expensive option. Measurement is the cheap one.

Catalyst's free AEO audit scans the domain on your work email and returns three things, AI Voice Share, Pipeline at Stake and an LLM breakdown. No account, no credit card, no call, results in about 60 seconds.

That gives you the shape of the gap. Catalyst's monthly work starts with a citation audit of 25 buyer-intent queries, measured against your top three competitors.

A competitor set turns absence into a comparison, because you can see who is named where you are not.

What to Look For in an Agency That Gets You Mentioned by AI Assistants

Use these six questions on any firm you are considering, including us. Catalyst's published answers are listed so you have something to compare against.

Does it publish its methodology? Catalyst's AI Visibility Index discloses the models tested, the prompt counts, the formulas and the coefficients behind every number it reports, and it says plainly when it retires one of its own figures.

Does it name a query set and a competitor set? Catalyst's citation audit covers 25 buyer-intent queries measured against your top three competitors.

How many assistants does it test? The Index runs ChatGPT, Claude, Gemini, Perplexity and Google AI Overviews, in a design of 10 prompts across 5 assistants in 2 runs, with one run using a decision-maker persona and one using a practitioner persona.

Who actually does the work? Catalyst names Austin Heaton, its AEO + GEO practice lead with 12 years in search, as the senior operator on this work.

Does the plan include work off your own site? If a proposal is entirely blog posts, it leaves out the sources AI cites.

Is there a written guarantee, read in a tool you own? Every Grow plan carries a written guarantee. AI visibility up at least 25% in 90 days, read in an AI-visibility tracker you own, or we work free until we hit it.

Ask where any guarantee is measured, and whether you can read that tracker yourself.

How Catalyst Runs the Work

Catalyst sells this as one line, SEO + AEO, in three tiers, Grow Lite, Grow and Grow Plus.

A tier covers 1, 2 or 3 topics guaranteed, 12, 20 or 20 articles a month built from expert interviews, 8, 12 or 15 placements a month on the sources AI cites, and 40, 50 or 75 prompts tracked. Grow Plus adds content for the executive team. Terms run 6 or 12 months.

The monthly cycle runs six steps, an AI citation audit, a content gap analysis against entity authority gaps, four to six structured pages published, structured data implementation, monthly citation tracking, and a monthly performance report.

If you are not ready for a retainer, the AI Readiness Sprint is a one-time engagement. It covers the questions buyers ask AI weighted by how close each is to a purchase, how ChatGPT, Claude, Gemini and Perplexity answer them today, the gaps, the site set up so AI and Google can read it, a 90 day plan, and 40 prompts loaded into a tracker you own with the week one baseline. It carries no guarantee.

Onboarding takes four weeks and results are stated at 90 days.

What Movement Looks Like

Published AEO results on Catalyst's AEO page are specific about the unit and the window.

Rise, a crypto payroll company, saw +860% Gemini session growth and 8,278+ total AI sessions in 12 months, with $8M+ pipeline influenced and 100+ countries reached.

Lumanu recorded 5,130 ChatGPT referral visits and 101 conversions from AI traffic in 60 days, at +1,746% ChatGPT referral growth.

Across clients, Catalyst reports +560% average AI click growth in 45 days.

Read those as examples rather than forecasts. Category, competitor density and starting entity position all change what 90 days produces.

Who This Is For, and Who It Is Not

Catalyst states its fit criteria openly. A B2B SaaS or technology company, a founder or executive willing to put their name on content, a sales motion that benefits from warm, pre-educated buyers, and readiness to invest in compounding assets rather than one-off campaigns.

The exclusions are equally explicit. Catalyst lists four reasons this work is not the right fit, no clear category or buyer-intent query set to optimize for, a need for immediate pipeline in 30 days when entity authority builds over months, a market that does not use AI for category research yet, and a wish to optimize for brand queries rather than buyer-intent queries. Pre-product companies are listed as out of scope.

Conclusion

The four common causes covered here are entity recognition, buyer-intent pages, presence on the sources AI cites and crawlability. An agency worth hiring works all four, names the queries and competitors it is measuring, tests more than one assistant, and puts its guarantee in a tracker you control.

Start by measuring where your brand stands with the free AEO audit before anyone proposes a plan.

Frequently Asked Questions

Why does ChatGPT never mention our brand?

This article groups the usual causes into four. ChatGPT does not recognize you as a distinct entity, no page of yours answers the buyer's actual question, you are missing from the sources AI cites, or your pages are not structured for machine reading. Catalyst's monthly citation audit measures citation share across 25 buyer-intent queries against your top three competitors.

Can an agency guarantee that ChatGPT will mention our brand?

What Catalyst guarantees is measured movement, not a specific sentence. Every Grow plan carries a written guarantee. AI visibility up at least 25% in 90 days, read in an AI-visibility tracker you own, or we work free until we hit it.

How long does it take before AI assistants start mentioning us?

Catalyst states results at 90 days, after a four week onboarding. The firm also lists "You need immediate pipeline in 30 days" as a reason this work is not a fit, because entity authority builds over months rather than weeks. Published client movement includes +560% average AI click growth in 45 days across Catalyst clients.

Why does our brand appear on one AI assistant but not another?

A single check on a single assistant is not a measurement. Catalyst's AI Visibility Index tests ChatGPT, Claude, Gemini, Perplexity and Google AI Overviews, running each prompt twice, once with a decision-maker persona and once with a practitioner persona.

What does Catalyst's free AEO audit measure?

Catalyst's free AEO audit scans the domain on your work email and returns AI Voice Share, Pipeline at Stake and an LLM breakdown. It needs no account, no credit card and no call, and results arrive in about 60 seconds. It is the entry point to every Catalyst offer, including the AI Readiness Sprint and the three SEO + AEO tiers.
