I have adwords and analytics account. In my adwords account it shows 3 clicks but my analytics shows 1 visits. What is going on? I dont understand analytics. And also my analytics shows one goal but my adwords is not showing any goal. Can you plz anyone help me?

The same problem is with me My analytics data shows 670 visits from google organic but my client sitting in US watching same data from his account (as I have given permission to his email account in my analytics) says he can see only 637 visits from Google organic and I don't know which is correct?

Please share if somebody knows the reason.
