As a business, you’re probably keen to hear how your customers – buyers, sellers, renters and landlords – found out about you. Did they see an ad in the newspaper or online, talk to friends, walk past your office, or find your website?

Increasingly, developments online with social media mean there are more places you need to be, so you don’t miss out on prospective business. But how seriously should you take your online presence? And how does word spread online?

According to information released by addtoany.com, a company which supplies one the most popular widgets that lets websites share stories across multiple social media sites, the most popular way users share information online is via Facebook.

With 24 percent of users sharing in this way, Facebook has even eclipsed good old fashioned email as the most common way users share links and info. Email comes a distant second with 11.1 percent, followed by the much hyped Twitter with 10.8 percent of the share.

So it’s not only your word of mouth, ads and shop windows you need to worry about – are your listings able to be shared on Facebook? Can users email them to a friend? And are you tweeting on Twitter?
