It should come as no surprise that 97% of the top 250 internet retailers have a Facebook presence.

However, did you realise that 61% of them have a Pinterest account? Or that just 67% are on Google+?

Social analytics firm Campalyst has pulled together this infographic to reveal how the top internet retailers use social media.

It uses data for the top 250 e-tailers from Internet Retailer’s top 500 from 2011.

It includes the average number of fans and followers, as well as breaking down who is performing best on each different network.

Obviously there is more to social media marketing than simply clocking up millions of fans, but it’s certainly a good place to start.
