SEO gets you ranked. AEO gets you quoted.
Search is splitting in two. Classic SEO is still how you earn blue links on Google. Answer Engine Optimization (AEO) is how you become the source that ChatGPT, Perplexity, Claude, Gemini and Google's AI Overviews quote when someone asks a question about your category. The two share a foundation — crawlable pages, clear structure, trustworthy content — but AI engines add new requirements: their crawlers must be allowed in robots.txt, your content must be readable without JavaScript, and facts about your business should be machine-readable through schema markup and files like llms.txt.
These tools cover both sides. Start with the AI Visibility Checker for a scored overview, use the generators to ship fixes, and use the page-level checkers before you publish anything new.
