Get warnings about unsafe sites When you encounter phishing, malware, unwanted software, or social engineering sites, you may get a red warning that says "Dangerous site." If you see this warning, we recommend that you don't visit the site.

To find out if a link is safe, just copy/paste the URL into the search box and hit Enter. Google Safe Browsing's URL checker will test the link and report back on the site's legitimacy and reputation in just seconds. It's that easy to use Google's URL scanner.

How to check if you're on Google blacklist. There are several ways to check whether a website's been blacklisted. First off, you can make a simple search on Google using the 'site' operator - site:yourdomain.com. If you see the warning message in the SERP results, then your website must be on the blacklist.

If Google suspects a site of hosting dangerous or spammy downloads, engaging in practices that are bad or dangerous to the user, or of being hacked, you will see a warning either in Google Search results or in your browser (or both).
