How to count number of visitors from different pages on same article?

I am promoting my viral content using different fb pages and want to track exactly how many visitor visit my website using that fb page.
I am planning to promote my content using friends fb pages and need to track that how many visitors he is sending on my website
So, the same article will share in our pages.
And the number of visitors will help in paying his share.
Any Suggestion?

You have an easy way to do it :

- Use your url who looks like " WEBSITEURL.COM/ARTICLE/" and add some parameters "?ref=friend1" , "?ref=friend2"

So the result will be : WEBSITEURL.COM/ARTICLE/?ref=friend1

You need to track the trafic of this url with you analysis tool (GA or others).

use UTM in your google analytics - https://support.google.com/analytics/answer/1033867?hl=en

We recommend looking up on the statistics Facebook Fan page shows and the ones that Google analytics has as well. However, what is best is to compare both results because even thou they are similar most of the time they are not the same. Another thing to point out is to make sure your website was programmed with Google analytics, in case it is not it won´t show you any results.
