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?

AEO Audit scores across six pillars: AI Visibility (22%), Brand Authority (23%), Content Quality (18%), Platform Optimization (15%), Structured Data (12%), and Technical AEO (10%). Each pillar reflects specific signals that AI engines use when deciding which sources to cite.

Evaluation stage

The battleground

How brands fare on comparison queries · category median 39/100

Loom leads head-to-head comparisons with an average evaluation score of 59, followed by Webflow at 57 and Imanage at 51. The median evaluation score is 39, so even the top performers cluster modestly above average. Eight brands in the evaluation set scored between 41 and 59 — a narrow band that suggests no runaway winner in direct matchups.

Each brand's evaluation score averages how AI responds to head-to-head comparison queries that mention them. Above-median brands win their comparisons more often than they lose.

Trends

Over the last 12 months

Too few audits to establish a trend. Only two months of data exist: March 2026 averaged 60 and April rose to 64 across 34 prompts. Nuclino gained 13 points month-over-month and Webflow dropped 9, but this reflects a single delta and cannot confirm sustained momentum.

Nuclino

Rose 13 points month-over-month — the largest gain in the category — and holds a 71 featured score. Strong signal in the wiki and lightweight-docs subcategory.

Semrush

Scores 74 on featured queries and 49 on evaluations. Straddles SEO and content planning, which may explain higher discovery mentions but weaker head-to-head performance.

Contentful

Featured score of 66 places it in the middle of the headless-CMS conversation. No evaluation data, suggesting it appears in shortlists but not comparison queries.

FAQ

Content & Knowledge questions, answered

Which content management system does AI recommend most often?+

No CMS dominates. The shortlist coverage rate is 0% across 36 prompts, meaning no brand appears consistently. Webflow scores 57 on evaluations and Contentful earns a 66 featured score, but both occupy narrow niches — design-first and headless, respectively.

What is the best headless CMS according to AI citations?+

Sanity, Storyblok, Prismic, and Contentful all appear in the data, but none dominate. Prismic and Contentful tie at 66 and 66 featured scores; Sanity scores 48 on evaluations and Storyblok 41. The headless segment is fragmented.

How do note-taking tools perform in AI recommendations?+

Nuclino is the standout, with a 71 featured score and a 13-point month-over-month gain — the largest increase in the category. It also scores 44 on evaluations, above the 39 median, suggesting solid presence in both discovery and comparison contexts.

Is there a rising trend in content and knowledge software citations?+

Not enough data to confirm trends. Only two months exist: average scores rose from 60 in March to 64 in April. Nuclino gained 13 points and Webflow dropped 9, but this is a single-delta snapshot.

Which digital asset management tools does AI cite?+

Azure Blob Storage ties for the highest featured score at 78, likely because it straddles infrastructure and DAM use cases. No other DAM-specific brands appear in the top eight featured candidates or evaluation set.

Do SEO tools get cited in content software queries?+

Yes. Ahrefs scores 78 and Semrush 74 on featured queries, both driven by overlap between SEO research and content planning. Semrush also appears in the evaluation set at 49, placing it near the median for head-to-head comparisons.
