Content with good SEO already has strong foundations for AEO, and the two practices certainly complement (not replace) one another. But AEO is different from SEO in a few ways:

• The goal of AEO is to show up in an AI-generated answer, while the goal of SEO is to rank at the top of a search engine results page.
• Answer engines in AEO seek a specific, direct answer; search engines in SEO seek a holistic, best resource.
• AEO is hyper-personalized with prompts that can be several paragraphs long; SEO is less personalized with “long-tail” keywords that are rarely more than nine words.
• AEO success metrics include brand mentions, citations, and share of voice; SEO success metrics include ranking positions, clicks, and traffic.
• In AEO, the results show up as a response in an answer engine or an AI-generated summary at the top of the Google SERPs — not always with clickable links. In SEO, the results are typically blue links that users must click through to read and fulfill their query.
