Occasionally, you should verify that your site is still appearing as it should in search engine results (especially if you don’t use managed hosting or another site scanning service).

Getting de-listed from Google or any other search engine could be devastating.

In the Google.com search bar type in site:yourdomain.com where you replace yourdomain.com with your domain name.  Example: site:scottontechnology.com

Your main domain should be in the top search results along with other popular or top-level pages.

Going directly to your website ie http://yourdomain.com might still appear normally as some malware redirects only affect search engine referral traffic.

Signs that your sight might be hacked, serving SPAM, or de-indexed

What to watch for:

1. Significant drops in traffic per analytics reports
2. A warning in search engine results stating that “This site might be hacked”
3. Long connection times in FTP access
4. Large backups or backups that fail to complete
5. Security alerts from Google Search Console (formerly Webmaster Tools)
