1. AddThis
AddThis.comWhat started as a simple tool to add social sharing buttons to a site has grown into a one-stop shop for website marketing and conversion tools. To get started, simply insert a few lines of code into your website, and then you can control which tools you use from inside your AddThis.com dashboard—no need to go back into your site and update the code whenever you make a change. Keep visitors engaged on your site for longer by using the “recommended content” tools. Encourage email signups and increase your social shares and followers, and better yet, track these stats within AddThis’s analytics.
