EV or Extended Validation Certificates (also known as "Green Bar" Certificates) are recognized and known as the most highly trusted type of SSL certificate. During the EV verification process, the issuing vendor or CA totally verifies that you are a legitimate business and in good standing above and beyond an OV verification process. Once this process is successfully completed and your EV SSL is issued, all of the browser indicators will be activated on your site to let your customers know that you can be trusted. The most important indicator that becomes active is the "Green Bar" in a user's web browser. Research shows that people are aware of the green bar and view it as being trustworthy. EV certificates are the only certificates where potential ROI exists...because more trust means more confidence; which could mean they are more likely to buy from you.
