Social Networking Buttons are Essential
If people are visiting your site more often because you are investing in PPC Advertising and because you are producing original, interesting content on a regular basis, you need to make sure that they can share what they read on your site. This means that you should place social networking buttons on every single page (and attach them to posts) so that it only takes the click of a button to share the information that you publish.
Internet users are lazy. Give them all the tools they need to make sure that your site and business finds its way around the Internet without you having to lift a finger.
