The Sociable Magento extension is a perfect solution for social bookmarking your products and store pages.
Nobody would deny the great impact the social media has on increasing website traffic, creating valuable backlinks, and getting referral customers. With the Sociable module, your site visitors are allowed to share any page of your Magento store on any social networking site.
