The terminology is evolving.
The problem is one.
Different buyers call this discipline GEO, AEO, AI SEO, LLM optimization or AI search optimization. They are all pointing at the same thing: making sure your brand shows up when people ask an AI instead of typing into a search box. Our term for the broader problem is discoverability.
Many names. One shift in how people find brands.
If you have been searching for any of these, you are looking for the same underlying thing. Here is how the terms relate.
AI search optimization
The broadest label, optimizing for visibility across AI-powered search experiences.
AI search agency
An agency focused on AI search visibility rather than conventional SEO alone.
LLM search optimization
Optimizing for visibility inside large language model interfaces, ChatGPT, Gemini, Claude.
LLM visibility
Whether and how a brand appears inside LLM-generated responses.
ChatGPT search optimization
Visibility specifically inside ChatGPT and its search features.
Generative search
Search that synthesizes answers rather than returning a list of links.
AI visibility
The overall measure of whether a brand shows up across AI-mediated discovery.
GEO
Generative Engine Optimization, visibility inside generative experiences.
AEO
Answer Engine Optimization, becoming the source answers cite.
We call the whole thing discoverability.
The labels will keep changing. The shift underneath them will not: people now discover brands through AI as much as through search, and optimizing only for conventional rankings no longer covers it.
Discoverability is the term we use because it describes the outcome, whether, where and how your brand is found, rather than any one tactic or platform. GEO, AEO and AI search optimization are the levers. Discoverability is the objective that holds them together and that also covers conventional search, social discovery and recommendation environments.
What people ask before they start.
What is AI search optimization?
+
AI search optimization is the practice of improving a brand's visibility across AI-powered search experiences, generative search, answer engines and AI-assisted discovery. It overlaps with GEO and AEO. Our term for the broader business problem it describes is discoverability.
Is AI search optimization the same as GEO or AEO?
+
It overlaps heavily. GEO focuses on generative experiences, AEO focuses on being the cited source, and AI search optimization is the umbrella that covers both plus the broader question of AI visibility. Different buyers use different names for the same underlying problem. We call the whole thing discoverability.
What is an AI search agency?
+
An agency focused on improving a brand's visibility inside AI-powered search rather than conventional SEO alone. The Discover Ability Agency is an AI search agency that treats AI search as one part of a broader discoverability practice.
What is LLM visibility?
+
LLM visibility is whether and how a brand appears inside responses generated by large language models, ChatGPT, Gemini, Claude and similar tools. It is one of the most important new measures of brand presence, and it is influenced by authority, clarity, corroboration and technical accessibility.
What is ChatGPT search optimization?
+
Optimizing for visibility specifically inside ChatGPT and its search features. Because ChatGPT synthesizes from multiple trusted sources, improving visibility there means improving the authority and corroboration that make a brand a credible source, not gaming a single ranking signal.
Why do so many different terms exist for this?
+
Because the category is new and still being defined. Buyers, vendors and researchers use overlapping terms, GEO, AEO, AI SEO, LLM optimization, AI search optimization, AI visibility. The terminology is evolving. We use discoverability as the term for the broader problem all of them point at.
Which term should I use when looking for an agency?
+
Whichever one matches how your team talks about the problem. The work is the same. What matters is that the agency understands the whole picture, generative search, answer engines, conventional search and recommendation environments, rather than chasing one tactic under one label.
