jooShare is a Joomla plugin that automatically adds social share buttons to your articles, making it easy for your visitors to share them on the most famous social network.
It generates tags like description, title, images directely from your page content and from page title to make posts shared on social networks from your visitors more attractive and generate traffic to your site.
Supported social network:
You can enable what social you want to show and what categories will be interested. You can also config a default image to be taken if your page doesn't have an image in its content and the position where the social buttons will be showed.
jooShare generates shorten urls using goo.gl (requires Google App Key free released by Google here).
You can also enable or not the Comments plugin and select the number of posts to show.
