Sneaky redirects
Visitors or people arriving from Google sent somewhere else, including redirects hidden in scripts or meta tags.
Free check
Gmork loads your homepage as a visitor, as Googlebot, and as someone clicking from Google, and looks for the visible signs of a hack. Free, no signup, about 30 seconds.
Hacked sites often look normal to their owners. These are the signs that show up for visitors and search engines instead.
Visitors or people arriving from Google sent somewhere else, including redirects hidden in scripts or meta tags.
Scrambled or obfuscated JavaScript and scripts loaded from unfamiliar domains, the way card skimmers and malware work.
Blocks of pharmacy, casino or loan links hidden from people but visible to search engines.
Spam words or links that appear when the page is fetched as Googlebot but not for a normal visitor.
Known in-browser mining scripts that use your visitors’ processors.
Invisible or off-screen iframes that load other sites inside your page.
Attackers often show their spam or redirect only to some visitors, so the owner never notices. The check requests your homepage three times and compares what comes back:
It also lists which recommended security headers the homepage sends. Those are hardening tips and never change the verdict. For the full header report, use the security headers checker.
A clean result means Gmork saw no visible warning signs. It is not a guarantee. If you have reason to worry, read how to tell if your website has been hacked for what to check next.
Yes. The check at gmork.com/hacked-check is free and needs no account. To keep it fair it is limited to 5 checks per visitor every 15 minutes.
It loads your homepage as a normal visitor, as Googlebot, and as someone arriving from a Google search, then looks for visible signs of a hack: sneaky or conditional redirects, injected or scrambled scripts, hidden spam links, crypto-miners, and unexpected frames. It also reports which recommended security headers are present.
No. It only sees what is publicly visible on the homepage at that moment. Some attacks only show to certain visitors, on certain pages, or at certain times. A clean result means no visible warning signs were found, not that the site is guaranteed to be clean.
Only for domains that are verified in a Gmork account. Those checks report whether a sensitive file is readable, never its contents. The free public check never probes for files.
