Free website checker
Enter a public website address. This free website checker fetches that page and reports what it found: a pass, a warn, or a fail for each check, with why it matters and how to fix it.
Use it when you want to know if your website is set up for phones, and to check if AI crawlers can see your site. The phone check looks for a viewport meta tag. The AI check reads robots.txt for GPTBot, ClaudeBot, PerplexityBot, and Google-Extended. For a closer read of AI search, use the AI search readiness check.
The checker also looks at HTTPS and the redirect to HTTPS, response status and time, the title and meta description, one h1, a tap-to-call tel: link, LocalBusiness or Organization JSON-LD, sitemap.xml, and llms.txt. It does not store the URL you submit. Cloudflare may keep its usual request logs.
Read the guides for plain English on why a business is missing from Google, what a website check costs, how to test a page on a phone, and whether AI tools can find a business.
A ranked report of what to fix on your website first, covering speed, SEO, mobile, and AI search visibility, delivered within 2 business days.
The price is $99, paid once. The payment page collects your email and website URL.

It fetches one public page, then robots.txt, sitemap.xml, and llms.txt. You get a pass, a warn, or a fail for HTTPS, response status and time, the title, the meta description, a mobile viewport tag, one h1, a tel: link, LocalBusiness or Organization JSON-LD, AI crawler rules, a sitemap, and llms.txt. Each line comes from that fetch.
This check looks for a viewport meta tag with width=device-width. That tag tells a phone to use the screen width. It does not open a phone, resize a window, or grade the layout.
The checker reads robots.txt and reports whether GPTBot, ClaudeBot, PerplexityBot, and Google-Extended are blocked from the whole site. A robots rule is a request to the crawler. It does not show what those crawlers have already saved.
No. The checker does not save the URL, the page, or the result, and it does not keep a list of addresses. Do not submit a private address. Cloudflare may keep its usual request logs, the same as for any other page on this site.
