AI Readiness vs. SEO — What's Different?
SEO gets you ranked in Google. AEO (Answer Engine Optimization) gets you recommended by ChatGPT, Claude, and Perplexity. They share a foundation but require different signals. Here's what you need for each — and what you only need for one.
SEO
Rank in Google and Bing search results. Success = keyword positions. Key signals: backlinks, keyword relevance, page speed, Core Web Vitals, structured data for rich results.
AEO — Answer Engine Optimization
Get cited in AI-generated answers. Success = mentioned in ChatGPT/Perplexity responses. Key signals: llms.txt, JSON-LD schema, AI crawler permissions, text-rendered content, explicit product clarity.

Frequently Asked Questions
What is the difference between SEO and AEO?
SEO optimizes for keyword rankings in Google and Bing. AEO (Answer Engine Optimization) optimizes for AI-generated answers — being cited and recommended by ChatGPT, Claude, Perplexity, and Google AI Overviews. They share some signals (structured data, meta tags, clear content) but AEO requires additional steps SEO doesn't need, like llms.txt and AI crawler permissions.
Do I need to choose between SEO and AEO?
No — most AEO improvements also help SEO. Adding JSON-LD, clear meta descriptions, and a sitemap benefit both. The AEO-specific additions (llms.txt, AI crawler rules, text-rendered content) are low-effort and don't conflict with SEO.
What is AEO?
AEO stands for Answer Engine Optimization — optimizing your product to be discovered, understood, and recommended by AI answer engines like ChatGPT, Perplexity, Claude, and Google AI Overviews. Unlike SEO which targets a list of links, AEO targets the 2-3 products an AI recommends when answering a product discovery query.
Which matters more for SaaS — SEO or AEO?
Both matter, but AEO is increasingly the higher-leverage channel for product discovery. Being in an AI's shortlist of 2-3 recommended tools converts better than a page-3 Google ranking. AEO should be treated as a first-class optimization target for any SaaS or developer tool.
