What this tool answers
"Is my redirect set up right?"
Pages should not chain through more than 1 redirect. If you click `/old-page` and bounce through `→ /new-page → /still-new-page → /final`, that's 3 redirects — every one slows the page and dilutes search authority.
"Is my CDN actually caching?"
The Cache-Control header tells you. If it says no-store or max-age=0, your CDN can't cache and every visitor hits your origin server. We translate this for you.
"What does Googlebot / GPTBot see?"
Some sites accidentally serve a different version to bots (paywalls, geofences, "this content requires JS"). Use the user-agent picker above to test as any bot and see exactly what they get back.
"Are my security headers right?"
HSTS, Content-Security-Policy, X-Frame-Options — they protect users from various attacks. We grade each and tell you what's missing in plain English.
