About Crawlsonar

Crawlsonar answers one question for brands: when people ask AI assistants what to choose, are you in the answer? It tracks that every week — and gives away the 51 checks that fix what AI and search see.

What it does

AI-visibility tracking asks the questions your buyers ask — several times per cycle, on ChatGPT, Claude, Perplexity, Gemini and Google AI Overviews, from clean sessions — and records whether your brand is named, who is named instead, and which sources the answers cite. You get share of voice over time, alerts when it moves, a weekly digest and exportable reports. Plans start free.

The free tools — AI readiness, llms.txt, robots.txt, structured data, DNS, email deliverability (SPF/DKIM/DMARC), TLS, security headers, Core Web Vitals and more — run without an account and explain every finding with the evidence and the fix. They stay free; the paid product is what a one-shot check can’t do: watch the number move.

How we score

Every score is explainable: a weighted list of checks that passed or failed, capped by the worst issue, so a red flag can’t hide inside a green number. The same engine scores the public AI & Web Readiness Leaderboard of 970 well-known sites. Tracking numbers are rates over many samples, never a single chat.

What we touch

Checks read public responses from the target you enter — server-rendered HTML, headers, DNS — with a polite, identifiable crawler that honours robots.txt and signs its requests (how the bot behaves). Analytics are cookieless and first-party. Email addresses are stored only with explicit consent and every marketing email has a one-click unsubscribe.
