Choose profiles
Enter a public URL and select up to eight crawlers or browsers, including a custom User-Agent.
HTML INSPECTION TOOLS / USER-AGENT ANALYSIS
See what each crawler sees.
Compare the HTML returned to search bots and everyday browsers. Check redirects, review full source, and preview up to eight User-Agent responses side by side.
START A NEW CHECK
Enter a website URL
We fetch the public HTML once for each selected User-Agent.
A changed response can result from User-Agent targeting, legitimate mobile variations, redirects, cookies, geo/IP filtering, or anti-bot rules. These requests imitate User-Agent headers; they are not real verified Googlebot/Bingbot crawls. Preview is static: scripts are disabled.
WORKFLOW
How Cloaking Checker works
Fetch the HTML
PHP requests the public page separately per profile, following and checking each redirect.
Inspect side by side
Switch every card together between static visual previews and the full HTML returned by the server.
FAQ
Frequently asked questions
Does a difference always mean SEO cloaking?
No. Mobile layouts, personalization, access restrictions, and redirects may legitimately return different HTML. Inspect the differences in context.
Is this the same as a real Googlebot crawl?
No. Bovolab sends a Googlebot User-Agent header from its own server. A website can also identify a real bot by IP, reverse DNS, cookies, or JavaScript behavior.
Does the preview run JavaScript?
No. For safety, the visual preview renders static HTML with scripts disabled. You may optionally load remote CSS and images for closer visual fidelity.
Are inspected HTML pages saved?
No. Crawled HTML is processed in server memory and returned to your browser. Bovolab does not create a history database or save the response files. Standard infrastructure logs may still exist.
