Google adds over 15,000 sites to their black list every day. Unfortunately most of the sites on the Google’s list are decent projects that were compromised by hackers who placed forbidden data on them.
Examples of such situations:
- PHP or HTML codes have been changed to malicious from outside
- Flash or .swf files have been added to the site.
Malicious programs are created in such a way as to maximally delay the detection time. Therefore they are usually detected by the search engine and not the owner of the website. The search engine detects suspicious behavior of the website, quarantines it, changing its color in the results to gray, and puts up a message that the site is unsafe to visit and scares the visitors away. Therefore in one day you can lose more than 95% of the sites traffic and with it both potential buyers and revenue.
The Blacklist Monitoring feature won’t only help you with Google Black List Monitoring, but McAfee, Norton, BitDefender, PhishTank, WebSecurityGuard, YandexSafeBrowsing and others. If your site is on the black list of one of the systems then most likely it was hacked and hackers sent spam or installed malicious software. You need an immediate response in order to eliminate the problem as soon as possible to keep the maximum traffic.
