Entrecard is your business card 2.0. Its part advertisement, part business card. It is a widget that you place on your blog, so that others can leave their Entrecard for you. You can also use Entrecard to promote your blog and launch free advertising campaigns.
Entrecard is a 125×125 image which represents you and your blog. You can select any image that you want. The more interesting the better. Try to create a nice image that can attract people’s eyes.
Above is the widget that you can show at your blog. I use the smallest version of the widget. You can find it at the bottom of the left sidebar.
In short, Entrecard brings you traffic. 😀
