Just because Facebook and Twitter aren’t driving you a ton of sales doesn’t mean you shouldn’t leverage them. Why? Because both Google and Bing use data from social sites in order to determine how high to rank your website.
For example, Moz started to rank on Google for “Beginner’s Guide” after Smashing Magazine tweeted out the guide. Shrushti moved from page 400 to page 1 of Google due to social media.
To show you how social media impacts your search rankings, I decided to create a gifographic (animated infographic) that explains the correlation.
