This is pretty interesting: Contrary to our impression, and perhaps that of many other people as well, only one percent of online purchases are made from social media sites like Pinterest, Twitter and Facebook. The main route for online purchases is by directly visiting a company’s web site. The second most common path comes from links that appear when you do web searches. You know: all the choices that come up on the screen. In third place are advertising links in search results you often see on the right hand side of the screen, as they are in Google. For repeat customers, email is effective. Thirteen percent of purchases by repeat customers were the result of an email link. If you bought from a place before, you’re a prime candidate to do it again. The study is from Forrester Research.
