Why use this instead of a standard Joomla social media share plugin? The key difference between this and other social media plugins is that this pulls the specific product information out of Virtuemart, removing unnecessary page information - this means that the shares on FB etc. are clean and have the important product info making them much more valuable for users, and for SEO alike.
The fact that it also includes so many customisable options, like CSS control for the buttons, font types, themes and languages means that it's a no brainer. If you want your users to share your products (thereby increasing traffic to your site) then this is a 'must have'.
Remember, deep-linking (links back to specific pages within your site) are very valuable from Google's point of view. This plugin gave me the best way to share just the right info, and was easy to install.
One more thing... this is the second product I've bought from Giang from Joomdonation and his support is nothing short of excellent. Couldn't be happier.
