SEO vs AEO vs GEO: which should B2B SaaS invest in first?

I asked ChatGPT and Gemini this question 12 times. None said AEO first.

said SEO first.
Fund the work SEO, AEO and GEO share first. Rewrite the pages that already get impressions, write one page for each buyer question and ask a fixed list of buyer questions every week. Add mentions on other sites after that.

What is the difference between SEO, AEO and GEO?

What is SEO?

SEO (search engine optimization) is the work of earning a ranked link on Google's results page.

What is AEO?

AEO (answer engine optimization) is the work of getting your company named and cited inside AI answers in ChatGPT, Perplexity, Gemini, AI Overviews and AI Mode.

What is GEO?

GEO (generative engine optimization) is the term from a KDD 2024 paper by Aggarwal and colleagues for page content changes that make generative engines quote a page. The paper reported visibility gains of up to 40% in generative engine responses.

How is AEO different from SEO?

SEO competes for a position in a list of links. AEO competes for a name inside one composed answer, and that answer draws on other sites as well as yours. The work underneath is the same, and it comes down to 4 things:

In our Oyster case study, Oyster got 11x more AI citations and 110% more organic clicks from pages it had already published.

How is GEO different from SEO?

GEO (generative engine optimization) changes page content so a generative engine quotes it. The page work is the same 4 things listed above.

Searches for "geo vs seo" also return local SEO pages: 2 of the first 8 results on November 5, 2026 had local SEO in the title (US, desktop).

How is AEO different from GEO?

GEO is the narrower term. It covers the on-page signals that decide whether an engine pulls from your page: cited sources, plain definitions and clear structure. AEO is the practitioner term for getting named in AI answers, and it adds 2 layers GEO leaves out: technical access (schema, robots.txt rules for AI crawlers and llms.txt) and how other sites describe you.

One plan covers both. A separate GEO plan would rewrite the same pages, the same company description and the same outside mentions.

What do ChatGPT and Gemini say to invest in first?

I asked both: "SEO or AEO: which should a B2B SaaS company invest in first?" I ran it 3 times on each engine in each of 2 rounds, on October 27 and November 2, 2026. That is 12 answers, from one of the tracked questions in our public experiment, Earning the Shortlist.

The result · 12 answers

All 12 put SEO first or as the foundation. 10 said SEO first outright. 2 Gemini answers said you cannot choose one over the other in isolation and kept SEO as the base. None said AEO first.

ChatGPT, November 2, run 1: "My recommendation: Invest in SEO first, then build AEO into your SEO strategy from day one."

Gemini, November 2, run 1: "SEO (Search Engine Optimization) first, but with an AEO (Answer Engine Optimization) mindset from day one." Its reason: "If you haven’t built foundational domain authority and ranking equity through SEO, AI search engines will not reference your product."

Agreement is no proof. One question on two engines is a small sample. Both ran through the consumer apps, ChatGPT logged out and Gemini on Flash-Lite, and answers vary by day. Only 3 of the 12 answers cited any source, all from ChatGPT.

Is SEO dead or evolving in 2026?

SEO still sends clicks, and fewer of them when an AI summary appears. Pew Research Center tracked 900 US adults and 68,879 Google searches, mostly in March 2025. Users clicked a traditional result in 8% of visits when an AI summary appeared and in 15% of visits when it did not. AI summaries appeared on about 18% of the searches.

On our side, Google showed an AI Overview for 44 of the 47 keywords we track, in the report dated November 2, 2026. It showed one for all 6 phrasings of this comparison when I checked on November 5 (US, desktop).

Pew measured all kinds of Google searches by US adults in one month. Our 47 keywords are our own list. Both show direction only.

How do you measure SEO, AEO and GEO?

For SEO, use Search Console: clicks, impressions and position for each page. For AEO and GEO, use a fixed list of buyer questions, asked every week on each engine and recorded as named, cited or absent. Lock the list and date it, because a reworded question is a different test.

How does SuperMarketers decide what to fund first?

We start every client with a Foundation month, built in their own tools and theirs to keep. On this site, a weekly Search Console report lists the pages to fix first: the ones with many impressions and few clicks. You can check where you stand with the 30-minute AI visibility audit, or see the services we run for B2B SaaS teams.
