WOT will work when you visit a website. WOT will also tell you about the risk of a site through the results of search engines like Google, Yahoo, Ask and others.
When doing a search on search engines. WOT is an icon displayed next to each result. A green icon indicates that the page is safe to visit.
If the icon is red then the website contains a risk to visit.
If you try to access a page that risk, WOT will warn you and block your access.
If you know what you’re doing, anyway, you can bypass the blockage by clicking the link Ignore the warning and go to this site at your own risk.
