AEO Audit is a free tool that scores B2B SaaS websites for AI search visibility — how likely they are to be cited by ChatGPT, Perplexity, and Google AI Overviews when B2B buyers search.

What is AI Engine Optimization (AEO)?

AI Engine Optimization (AEO) is the practice of structuring content, entity signals, and technical infrastructure so that AI engines cite your brand in generated answers. It extends traditional SEO to cover ChatGPT, Perplexity, Gemini, and Google AI Overviews.

How does AEO Audit score websites?

Headless CMS

The headless CMS market shows strong consensus around three leaders—Contentful, Sanity, and Storyblok—each shortlisted in roughly two-thirds of evaluations with identical model diversity (4), suggesting broad cross-industry appeal. A second tier emerges with Prismic and Strapi near 48%, followed by Directus at 38%, indicating differentiation likely driven by deployment preferences (cloud vs. self-hosted) and developer experience priorities. The 18-brand consensus pool against only 12 evaluation brands reveals a fragmented market where buyers recognize many options but concentrate serious consideration on a narrow set.
