AI-generated search is changing how people find companies online. Instead of clicking through pages upon pages of Google results, users are increasingly getting direct answers from AI tools like ChatGPT, Gemini, and Perplexity.
Because of that, more businesses are starting to rethink how they approach visibility online.
That’s where GEO comes in. Over the last year especially, brands have started looking for the best GEO agencies in 2026 to help them adapt to AI-driven search and conversational discovery platforms. Some companies are even starting to hire GEO experts specifically to figure out how their brand appears inside AI-generated answers.
What’s Generative Engine Optimization?
So, what is generative engine optimization?
In simple terms, GEO is about improving how a company shows up inside AI-generated responses. Traditional SEO still matters, but GEO focuses more on things like authority, brand mentions, structured content, and whether AI systems can easily understand and reference your business.
A lot of this overlaps with SEO, content marketing, and digital PR. The difference is that GEO is more closely tied to how AI tools retrieve and summarize information. As conversational search keeps growing, businesses are putting more money into AI search optimization strategies instead of relying entirely on traditional rankings.

Not every SEO agency automatically understands GEO yet. A lot of companies are still figuring it out in real time. If you’re comparing agencies, it’s definitely worth looking at their authority-building experience, content quality, digital PR capabilities, technical SEO knowledge, and their experience with conversational search trends.
Some businesses may only need small adjustments to existing SEO strategies. Others may want to fully hire GEO experts to help rethink how their brand appears inside AI-generated search results.
