If your website has been hacked, Google might show a warning label next to your website in the search results.
What is hacked content?
According to Google, hacked content is ‘any content placed on your site without your permission as a result of vulnerabilities in your site’s security.’
Google tries to keep hacked content out of their search results. Hacked content can potentially install malicious content on your website. Google recommends that you keep your site secure, and clean up hacked content when you find it.
Clean up hacked content
When your website has been hacked, you should clean it up and you should inform Google about the fix. Google’s John Mueller said on Twitter that malware reviews are quicker than hacked content reviews:
Usually just hacked content wouldn't show an interstitial, it would just show the note in search. If it's showing an interstitial, that would go through the malware side, where reviews are generally pretty quick.— ? John ? (@JohnMu) November 7, 2019
Malware or hacked content? Malware reviews are generally really fast; hacked content can take a bit longer.— ? John ? (@JohnMu) November 7, 2019
