WOT is a community-based, free safe surfing tool for browsers that provides website ratings to help web users as they surf online. Web of Trust adds traffic lights to internet searches so you can be sure which websites you can trust. WOT ratings are powered by users all around the world who have rated millions of websites based on their experiences. Third-party sources are also used to warn you about malware and other technical threats. You will see a green, yellow or red icon next to search results when you use Google, Yahoo!, or Bing, on links in social networking sites like Facebook and Twitter, on online email like Gmail, Yahoo! Mail and Hotmail, and other popular sites like Wikipedia. Green indicates a trustworthy site, yellow tells to be cautious, while red indicates a potentially unsafe site. It gives you some decent protection while surfing around with a trivial amount of searching delay.
