TL;DR: AEO (Answer Engine Optimization) is the same thing as GEO, AI SEO, and LLM SEO. Different agencies use different acronyms for the same work: optimizing content to get cited by AI systems. Animalz uses AEO terminology. Omniscient Digital calls it GEO. The work is the same: topical authority, quality content, citation monitoring. Most agencies charge $10-30k/month. The question isn't which acronym to use. It's whether you need an agency or can build the system yourself.
Best AEO Agencies in 2026: Answer Engine Optimization Ranked
Last updated: May 2026
The top AEO agencies are Animalz (explicitly uses AEO terminology, $10-30k/month est.), Omniscient Digital (calls it GEO but same work, $8-25k/month), and Omnius (B2B SaaS GEO specialist). The terminology varies. The work doesn't.
AEO stands for Answer Engine Optimization. It's one of several acronyms agencies use for the same thing: optimizing content to get cited by AI systems like ChatGPT, Perplexity, and Google AI Overviews.
Other names for the same work:
- GEO (Generative Engine Optimization)
- AI SEO
- LLM SEO
- SAIO (Search Artificial Intelligence Optimization)
- GRO (Generative Response Optimization)
The acronym an agency uses tells you more about their marketing than their methodology. This guide focuses on what the work actually involves and which agencies do it well.
What AEO Actually Means
Answer Engine Optimization means optimizing content so AI "answer engines" cite you:
- Perplexity - Searches the web, cites sources directly
- ChatGPT - Browses web for some queries, cites sources
- Google AI Overviews - Summarizes from Google's index
- Claude - Uses training data, limited real-time browsing
The optimization is mostly familiar:
- Create authoritative, comprehensive content
- Build topical authority through content clusters
- Get mentioned on sites these systems trust
- Structure content for easy answer extraction
The new part is monitoring: tracking where and how often you appear in AI-generated answers.
AEO vs GEO vs AI SEO
| Term | What It Means | Who Uses It |
|---|---|---|
| AEO | Answer Engine Optimization | Animalz, some SEO consultants |
| GEO | Generative Engine Optimization | Omniscient, Omnius, academic papers |
| AI SEO | AI Search Engine Optimization | Generic industry term |
| LLM SEO | Large Language Model SEO | Technical/developer audiences |
| SAIO | Search AI Optimization | 42DM |
| GRO | Generative Response Optimization | Intero Digital (trademarked) |
Bottom line: These are all the same thing. Don't choose an agency based on which acronym they use.
