I use Facebook Insights for websites and Facebook buttons on my site. However, the data reported by the two do not match. It always seems to be the case that the count reported by the buttons is significantly higher than the count reported in Facebook Insights.
For example, this page http://www.appmyworld.com/blog/top-5-iphone-and-ipad-apps-of-the-week-10412.html has a count of 52 for Facebook which is made up of 19 likes, 21 shares and 12 comments according to AddThis and confirmed by http://sharedcount.com
However, going into Facebook Insights for my website and looking at that specific page it shows only 4 total actions which is made up of 1 like and 3 shares. At the very least I would expect it to show a total count of 40 made up of 19 likes and 21 shares (I'm not sure it would track the 12 comments).
Any thoughts on why this may be happening? My concern is if our website is not getting credit for the Facebook activity?
Which panel are you getting the Facebook insights figures from? Make sure your app ID is correct on your page, and make sure you're accounting for the proper time frame. You can read about how to use Facebook Insights here: https://developers.facebook.com/docs/insights/
