Hubspot has just collected some data from 5,000 blogs that reveals the importance of Twitter and Facebook.
Twitter is certainly revealed in this study as the prime driver of traffic; having a retweet button on your blog makes it easy for people to share your content.
Sharing increases your search engine optimization
How Google ranks the importance of a website or blog and how high it will appear in search results is based on many factors.
One of the most important is the number of other websites linking to your site. The more websites that link to your content and the more credible they are (a link from The New York Times will be more valuable than a link from a small company website) gives Google a good idea how valuable your content is. This is called an inbound link (an example of this is the link to Hubspot that I have included in this blog post).
This study revealed that combined sharing on Twitter and Facebook increased inbound links by 149 percent more than a post not shared at all.
