AI search is changing how customers discover, compare and choose businesses.
For years, SEO was about ranking on Google.
But in 2026, more buying journeys are starting inside AI-generated answers from platforms like ChatGPT, Gemini, Perplexity, and Google AI Overviews.
That creates a new challenge for businesses.
It is no longer enough to be indexed.
You need to be understood, trusted, cited and recommended.
That is where Generative Engine Optimisation, or GEO, comes in.
The best GEO agencies help businesses improve how they appear inside AI-generated answers by strengthening technical SEO, structured content, entity clarity, authority signals, digital PR, and AI visibility tracking.
Gartner predicts that traditional search engine volume could decline by 25% by 2026 as users increasingly shift toward AI chatbots and answer engines.
That means businesses now need agencies that understand visibility inside AI systems, not just traditional Google rankings.
A GEO agency helps businesses increase their visibility inside AI-generated answers, AI search results and large language model responses.
Unlike traditional SEO, which focuses mainly on rankings, traffic and search engine results pages, GEO focuses on whether AI systems understand, trust, cite and recommend your brand.
A strong GEO agency should be able to help with:
The goal is simple:
When your ideal customer asks an AI platform who to trust, your business should be one of the names it recommends.

Not every SEO agency understands GEO.
As AI search evolves, businesses need agencies that understand how visibility works inside AI-generated answers, not just traditional search rankings.
When evaluating a GEO agency, businesses should look for:
The strongest GEO agencies do more than optimise pages.
They help businesses become:
Traditional search behaviour is changing rapidly.
The commercial impact of AI visibility is already becoming measurable.
Businesses are beginning to see measurable differences between being searchable and being recommended inside AI-generated answers.
Research from Adobe found that traffic from generative AI sources to retail websites increased by more than 1,200% between July 2024 and February 2025.
AI visibility is also beginning to influence purchasing behaviour directly.
Research highlighted by 6sense found that 94% of B2B buyers now use generative AI tools during some stage of the buying process.
That means AI platforms are no longer just informational tools.
This makes visibility inside AI-generated answers commercially important for brands across nearly every industry.
Businesses are no longer competing:
They are competing to become the answer AI systems trust and recommend.
And that requires:
Not all SEO agencies are GEO agencies.
When evaluating GEO partners, businesses should look for agencies that understand:
Can they explain:
Do they create:
Do they focus on:
Can they measure:
AI search is already changing how customers discover businesses.
The companies that win in this new environment will not simply be the ones creating more content or chasing rankings; they will be the ones AI systems understand, trust, and recommend.
That is why GEO is becoming a critical part of modern visibility strategy.
At Tenacious AI Marketing, we help businesses build AI visibility systems through:
So they become visible inside the answers that increasingly shape customer decisions.
Because in the AI era, visibility increasingly becomes a recommendation.
A GEO agency helps businesses improve visibility inside AI-generated answers and AI search environments.
SEO focuses on rankings and traffic. GEO focuses on citations, recommendations, and AI visibility.
ChatGPT, Google AI Overviews, Gemini, Claude, Copilot, and Perplexity are currently among the most important.
AI citations influence whether a business is referenced, recommended, and trusted inside AI-generated search experiences.
Yes. In many industries, GEO opportunities are still relatively early, creating strong visibility potential.
Not entirely. GEO is evolving on top of SEO and changing how visibility works inside AI-driven discovery.
Tenacious focuses on visibility systems, authority ecosystems, and AI recommendation strategy, not just rankings or traffic.
