SEO is for blue links. AEO is for AI-generated answer boxes. GEO is for conversational LLM answers. They are three distinct disciplines that target three distinct surfaces, and they require three distinct sets of tactics.
This is the AdMax comparison guide. We cover what each acronym means, which buyers see which surface, what the leading tactics are for each, and how to decide which to prioritize first. For deeper dives: What is AEO and What is GEO.
SEO — Search Engine Optimization. Making your pages rank in the traditional ten-blue-links search result. Buyers see a list, click a link, land on a page.
AEO — Answer Engine Optimization. Making your brand a cited source inside AI-generated answer boxes on Google AI Overviews, Perplexity, You.com, and SearchGPT. Buyers see a synthesized answer with citations, sometimes click a citation, sometimes do not.
GEO — Generative Engine Optimization. Making your brand show up inside conversational answers from ChatGPT, Claude, Gemini, and other LLMs when users ask for recommendations. Buyers see a recommendation with or without attribution.
SEO lives in Google, Bing, DuckDuckGo, and the long tail of vertical search engines. Same for the next decade.
AEO lives inside the AI Overview at the top of Google search, the Perplexity answer page, the You.com answer pane, and SearchGPT. It is a synthesized paragraph plus a small set of source citations.
GEO lives inside a private conversation between a buyer and ChatGPT, Claude, or Gemini. The brand recommendation arrives without a SERP visible, sometimes without a clickable link.
SEO tactics: on-page keyword targeting, internal linking, backlinks, content depth, technical site speed, Core Web Vitals, mobile UX. The toolkit that has existed since 2002, refined.
AEO tactics: JSON-LD schema rollout (Organization, FAQPage, HowTo, Article, Service, BreadcrumbList), answer-shaped content, citation-ready facts, llms.txt, clean sitemap.xml. Plus E-E-A-T signals (real About page, organizational schema, author bios). Heavy on structure, light on links.
GEO tactics: trade press bylines, podcast appearances with public transcripts, public open-source contributions, Wikipedia-adjacent sourcing, consistent named presence across the web. Heavy on off-site, light on on-page.
SEO: weeks to months. Visible movements inside three to six weeks for low-competition terms, three to twelve months for high-competition.
AEO: two to four weeks. AI Overview and Perplexity recrawl quickly. Schema and FAQ work can show up in answers inside a month.
GEO: quarters to years. LLM pre-training cycles are slow. First quarter is investment; second quarter is when the next training cycle ingests the work; third quarter is when recommendation rates move consistently.
SEO metric: keyword position, organic traffic, organic conversion rate.
AEO metric: mention rate inside AI overviews, citation rate (URL specifically named), click-through rate from the answer box.
GEO metric: recommendation rate inside LLM answers, mention quality (does the description match your positioning), brand consistency across LLMs.
For most B2B and high-consideration B2C brands, the answer is "all three" because buyers move across all three surfaces during their decision. The right question is which one to start with given current state.
If your traditional SEO is broken (no schema, no sitemap, no internal linking), fix that first — the foundation makes both AEO and SEO easier. If your SEO is healthy and your AI presence is weak, AEO is the fast lane for visible lift inside a month. GEO should be running in parallel from day one because it takes the longest to compound.
