AEO vs SEO: what differs and which one to do first
AEO vs SEO is a question about what you are trying to win. SEO earns a ranking and a click. AEO (answer engine optimization) earns a mention or a citation inside the answer that ChatGPT, Gemini, Perplexity or Google's AI Overviews writes. For most businesses the answer is both, in a set order: build the SEO basics first if your site has little search presence, and start AEO now if you already rank but clicks are flat.
What SEO and AEO share
The engines read your pages, so the foundation is the same. Crawlable pages, clear titles, one page per offer, internal links, accurate prices and policies. Skip those and neither discipline works.
Ranking also feeds citations. Ahrefs (March 2026) found that 38% of AI Overview citations come from the top 10 results and 31% from positions 11 to 100. Page one helps. Nearly a third of citations still go to pages below it, so a page that answers a question well can be cited without ranking well.
AEO vs SEO side by side
| Question | SEO | AEO |
|---|---|---|
| What you win | A ranked link and a click | A mention, citation or recommendation inside an answer |
| Unit of work | The page and its keyword | The passage, the offer and the entity (your business as a named thing) |
| Measured by | Rankings, clicks, sessions | Citations across a set of buyer prompts, sessions from assistants |
| Off-site signal | Backlinks | Third-party mentions of your brand |
| Local data | Google Business Profile | Google Maps for Gemini, Bing Places and Yelp for ChatGPT and Perplexity |
Where the work differs
Answer-first writing comes first. A search page can open with a story and still rank. An assistant lifts a passage, so the answer to the question goes in the first paragraph under each heading, with the price and any exceptions stated plainly.
Off-site mentions come next. In a study of 75,000 brands, Ahrefs measured a 0.66 correlation between third-party brand mentions and AI Overview visibility. Backlinks scored 0.22. That points you at review sites, directories, trade publications and the forums where your buyers ask questions.
Local data is the third difference. Gemini grounds local answers on Google Maps. ChatGPT and Perplexity use Bing Places and Yelp. The SOCi Local Visibility Index 2026 shows how uneven the results are: ChatGPT recommends 1.2% of multi-location businesses, Perplexity 7.4% and Gemini 11%. A listing that is right on Google and missing on Bing Places is only half done.
Some popular AEO tasks can wait. Google discourages the llms.txt file, and AI crawlers rarely request it. Structured data correlates only weakly with AI citations. Keep it for rich results and feed consistency, and spend your hours elsewhere.
Which one your business needs first
The order depends on where you stand today. Three situations cover most owners.
- You have little search presence. Start with SEO: an indexable page for each product, plan or service, correct titles, a sitemap. Answer engines have little to quote from thin pages. Our SEO page shows how we scope that work.
- You rank and clicks are falling. Start with AEO. Ahrefs (300,000 keywords) found the first Google result loses about 58% of its clicks when an AI Overview appears, and SparkToro / Similarweb report that 68% of US Google searches end without a click.
- You run several locations. Start with listings. Make the name, address, hours and services match on Google Business Profile, Bing Places and Yelp, so every engine reads the same business.
JCS Fashions, a 4,878-product Shopify apparel store in Milpitas and LynkAI's first customer, ran both kinds of work in 2026. Google clicks went from 205 a month in January to 626 in September. Guide-page clicks went from 0 in February to 231 in August. Sessions from AI assistants went from 20 in January to 569 in October. The full customer story has the monthly detail.
A plan for this week
- Write 25 questions a buyer asks before purchasing, in the buyer's words.
- Ask each one in ChatGPT, Gemini and Perplexity. Record which businesses are named and which pages are cited.
- For every question where you are missing, find the page on your site that should answer it and rewrite its opening so the answer comes first.
- Check your name, address and category on Google Business Profile, Bing Places and Yelp.
- List five sites that mention your competitors and leave you out. Those are your outreach targets.
