SEO Crawlers & Site Audit: AI Visibility Ranking

Website crawling and technical SEO audit tools: crawl a site, find indexability and content issues, and track fixes. Right now, Screaming Frog is the brand AI assistants recommend most, with a Visibility Score of 72 and the #1 spot in 53% of answers. Head-to-head: Screaming Frog vs Ahrefs →

These rankings are measured from what the three models know from training, not a live web search. The live-web grounded surface is rolling out across the index. Methodology.

Screaming Frog owns the default slot; everyone else competes for scraps.

Screaming Frog is the reflex answer across all three models, named first in 53% of answers and pulling a score nearly 18 points clear of Ahrefs in second. Claude is its strongest advocate with an 85 score, while Gemini is the skeptic at 57.9, which is worth watching as the gap between Claude and Gemini recommendations could shift brand perception among buyers who cross-reference AI tools. Lumar is the outlier inside the outliers: it scores 50 on Gemini but sits below 21 on both ChatGPT and Claude, meaning its AI visibility is almost entirely dependent on one model.

The ± under each score is the reliability band: how much the number would move if we re-ran the identical measurement. It is tight because each prompt is sampled multiple times. It is not the same as how much the ranking depends on which prompts we ask — a separate, wider figure shown on hover.

Just below the cutoff: Xenu's Link Sleuth (5.6), BrightEdge (4.3), SEO PowerSuite (4), ScrapingBee (4), Jina Reader (3.5). 69 brands were scored in this category; the leaderboard shows the top 15.

Visibility Score: position-weighted presence across all measured answers, 0 to 100. A score of 100 means the brand was the first recommendation in every answer. Every point in a trend line is a live monthly measurement; there is no modeled or backfilled history. Full methodology.

Openness 28/100: the share of this category's recommendation weight not held by the leader.
