SEO and AEO sound similar, but they aim at different finish lines. SEO gets your page to rank in Google's list of links. AEO gets your business cited inside the AI answers that ChatGPT, Perplexity, and Google's AI Overviews now give. They share most of the same foundations — and for a modern small business, you want both.
What is SEO?
Search engine optimization is the practice of getting your pages to rank in traditional search results — the blue links on Google. It rewards relevant content, clear structure, fast pages, quality links, and crawlability. The goal is a top position and a click.
What is AEO?
Answer engine optimization is about being the source an AI assistant quotes when it answers a question. Instead of competing for a click, you compete to be the answer. It's a newer discipline — here's a full primer on what AEO is.
SEO vs AEO at a glance
| SEO | AEO | |
|---|---|---|
| Goal | Rank a page so a human clicks | Be the source an AI cites |
| Where you win | Google's blue links | ChatGPT, Perplexity, AI Overviews |
| Optimizes for | Keywords, links, crawlability | Clear answers, structure, trust |
| Success looks like | A top ranking and clicks | A citation in the AI's answer |
Where they overlap
Most of the work is shared. Clear, well-structured content, fast performance, accurate facts, semantic HTML, and structured data help you rank AND get cited. Strengthen one and you usually strengthen the other.
Do you need both?
Yes. Classic search isn't going away, and AI answers are growing fast — ignoring either leaves leads on the table. Because the work overlaps, doing both isn't double the effort. Start with solid SEO, then layer AEO on top: get cited by ChatGPT and Perplexity.
