The Terms at a Glance
| Term | Stands for | Main goal | Where it shows up |
|---|---|---|---|
| SEO | Search engine optimization | Rank pages in search results | Google and Bing blue links, Maps |
| AI SEO | SEO for AI search | Rank in search and appear in AI answers | Google, AI Overviews, AI Mode, AI search tools |

Why There Are So Many Names
The way people search changed faster than the industry agreed on a name. “Generative engine optimization” came from a 2023 research paper on how to influence AI-written answers. “Answer engine optimization” is older and grew up around featured snippets and voice search. Agencies and tools then added “AI SEO”, “LLM SEO” and “AI visibility”. The names compete, but the work underneath is largely the same.
How They Fit Together
- SEO is the foundation. Google says its AI features rely on the same index and best practices as normal search. If Google cannot crawl and trust your site, its AI will not quote it.
- AEO makes your content answer-shaped. Clear questions as headings, short direct answers, tables and FAQs.
- GEO makes your business recommendable. Consistent facts about you across your site, Google Business Profile, directories, reviews and lists, so AI can name you with confidence.
- AI visibility measures the result. Tracking the real questions buyers ask in each AI tool, and who gets named.
What Changes in Practice
| Old SEO habit | What GEO and AEO add |
|---|---|
| Write long pages around one keyword | Answer real buyer questions first, in plain sentences AI can quote |
| Hide prices to force a call | Publish starting prices so AI can repeat them |
| Anonymous company content | Named authors and clear company facts |
| Measure rankings and traffic | Also measure AI mentions, citations and AI referral visits |
| Build any backlinks | Earn mentions on trusted lists, directories and industry sites |
