I have a few questions, I hope you can help me:
1. What does the Tweet Button count exactly? I see a mismatch between the number of shares (in AddThis) and the number in the counter on my site?
2. I only have 3 Buttons on my site: Facebook Like, Tweet and G+. But in my analytics sometimes 'facebook' pops up (less times than 'facebook like', but still). What's the difference between these shares?
3. Clicks: when I check the numbers in Google Analytics (traffic via Facebook for example), these numbers are much higher than the clicks. Why is there a mismatch between these numbers?
