There are more than 300 WordPress plugins to help you like, share, or tweet your content and blog. But let’s be honest, most of them just couldn’t make it to being a social integration plugin. Social integration is important for your WordPress blog or website. It is best for self promotion, social engagement, and having a viral value. There are so many great tools to make it possible, and make your social network a lot easier.
Social by Mailchimp is one of the best social media plugin in WordPress. This plugin brings Twitter and Facebook to your WordPress site. It handles all the three aspects of social engagement that is why I like Social by MailChimp.
AddThis is a great plugin to getting users to share your content without forcing them to. One cool feature of AddThiis is that it has analytics so you can track your content across all social networks. It gives you a detailed report similar to Google Analytics.
