FAQ & usage tips

Q:Is TDK & Crawler Checker free?

Yes. Completely free and no login is required for single URL audits.

Q:Why simulate different User-Agents?

Many websites, CDNs, or SSR frameworks serve different content to search engine bots (like Googlebot) compared to regular desktop browsers. Testing multiple UAs reveals cloaking, missing SSR tags, or bot blocking.
