Take a look at Followerwonk (it is good for Twitter), ViralWoot (good for Pinterest), Likealyzer (Good for Facebook). Buffer is good for managing and automating social media account management.
Facebook specifically allows you to add competitors to watch & monitor. Although I wish there were more metrics, simply click on your facebook page, insights, pages to watch, and you can compare the performance of your page and posts with similar Pages on Facebook. Hope this helps!
