FAQ
What's the difference between AEO, GEO, and SEO?
SEO optimizes for search rankings. AEO optimizes for being the direct answer to a question. GEO optimizes more broadly for being cited by generative AI. They reinforce each other.
Is Share of Model the same as share of voice?
Related but distinct — share of voice measures media/social mentions, Share of Model measures presence inside AI-generated answers specifically.
What's the difference between Smart Bidding and AI Max?
Smart Bidding sets bids automatically toward a goal. AI Max is a broader layer that also expands keyword reach and creative — they work together.
