How One of the Big Six Global Holding Companies Built a Market-Leading GEO Practice on Evertune

Evertune worked with one of the largest media agencies in the world to stand up a a scalable AI visibility consulting practice. As one of the big six global media and advertising holding companies, this agency is responsible for advising major brands on media, SEO, and digital transformation. As brands began asking how they appear in AI search, the agency needed a credible answer and a technology partner capable of turning that answer into a repeatable service.

The challenge

As buyers increasingly turn to AI models for product research and recommendations, agencies are among the first to feel the commercial impact. Clients now expect clear answers on where their brands appear in ChatGPT, Gemini, and other large language models, why competitors are recommended ahead of them, and which actions will improve their standing. The agency set out to meet that demand by developing an AI visibility consulting practice designed to scale across its client base, but needed a technology partner to execute it.

"We were increasingly getting asked about GEO by our existing clients, and to include AI visibility in pitches. We needed to provide compelling, credible responses and a clear position on how to build and execute a market-leading GEO strategy. If we couldn't do that, our relationships and the associated revenue were at risk."

Why other platforms fell short

Before selecting Evertune, the agency evaluated Scrunch, BrightEdge, Semrush, and Authoritas. Four consistent shortcomings emerged across these options:

  • The optimization workflow lacked clarity. Insights were difficult to act on, with no clear path from a finding to an action that would improve AI visibility.
  • No platform could consistently answer the three questions clients prioritized: what appears in LLMs, why it appears, and how to improve it.
  • Data sampling was inconsistent, which reduced confidence in the results.
  • Guidance on prompt formation and methodology was limited.

The solution

Evertune became the foundation of the agency's AI visibility offering. Two elements proved decisive: the platform's features and measurement methodology, and the strategic guidance provided by Evertune's customer support team. Together, the two organizations established a new consulting service that addressed client needs quickly.

"Evertune is the core of our AI visibility solution. The combination of the technology and the account support helped us quickly stand up a new consulting solution that has achieved product-market fit."

The agency developed a repeatable audit and optimization workflow built around a defined sequence. The workflow begins with the AI Brand Index to establish unaided awareness, a measure of how often AI models recommend a brand in open category questions where the brand is never named. Consumer Preferences then identifies the specific attributes where the brand trails competitors in AI responses. Content Studio generates content targeting those gaps, written in the brand's voice and structured for AI retrieval. The result is an enterprise GEO audit and follow-on consulting engagement that clients act on.

The team also identified Evertune's customer support as a distinct differentiator. The Evertune team worked alongside the agency as an extension of the practice, training the agency's consultants on how AI models evaluate and cite sources, helping interpret tracker data for specific client situations, and partnering directly on the design and ongoing iteration of the audit methodology. This hands-on involvement shortened the time it took the agency to operate the platform independently and to advise clients with confidence.

"The client support has been exceptional: fast, responsive, and strategic. They go well beyond answering questions and helping us leverage the platform. The Evertune team has acted as a true partner in building our practice. They took the time to upskill our team on how large language models actually work, helped us interpret the data for specific client situations, and worked with us directly to develop and iterate our audit methodology. That combination of deep expertise and customer centricity is rare, and it is a big reason we were able to stand up a credible consulting solution so quickly."

Results

The practice delivered commercial results quickly. Evertune data anchored the strategic response in a media pitch defense, expanding the account's scope and securing what became the agency's largest SEO and GEO client.

For one of the agency's largest financial services clients, Evertune supported a GEO strategy and roadmap that included a market-first sponsored content proof of concept. That work moved the client to the #1 position in both ChatGPT and Gemini.

The broader outcome is a new and expanding revenue stream, built on a repeatable audit that performs consistently with clients and on measurable gains for those who implement its recommendations. The work has also established the agency as a credible authority on AI visibility, reinforcing its position as a future-fit media, SEO, and transformation partner.

"Evertune is the clear leader in helping brands understand where they're showing up in LLMs, why they're showing up, and the specific actions to take to increase their visibility. Their deep understanding of LLMs, unique consumer panel insights, large-scale data sampling, aggressive development roadmap, and customer centricity make them an excellent partner. I'd recommend them to all my colleagues, though I'd prefer they don't work with my competitors."

Looking ahead

The agency is focused on scaling its AI visibility and GEO offering across additional clients and categories. In partnership with Evertune, the team will continue to refine the audit and optimization workflow, extending a practice that began as a response to client questions and has become a growing line of business.

Evertune is the first Generative Engine Optimization (GEO) platform built to explore, measure, act and advertise across the entire AI customer journey, connecting brands directly to ChatGPT Ads and programmatic advertising partners like The Trade Desk and Index Exchange. Where most GEO tools sample each prompt once a day, Evertune samples every prompt 100 times per model across 11+ AI models, delivering statistically significant visibility data at half the cost of competing platforms. Evertune's agents do the work for you: a prompt agent mines over 150 million real user conversations to find the exact questions buyers ask, an insights agent tells you what to do next each week, and an ads agent builds a complete ChatGPT campaign around your visibility gaps. From there, Evertune closes the loop with website optimization, data-driven content creation, source-level influence mapping and paid activation through affiliate and programmatic AI retargeting partners. Founded by the team that pioneered programmatic advertising at The Trade Desk, now building the next marketing channel.
