Training with GA or another application

I will ask for a quote for training on GA or a similar application that will have the function to monitor hits to the main website from one traffic source such as a forum, but from different forum posts. Measuring the conversion of the entrance to the site from each post on the same forum.

Information from Useme: bidding is only possible if:

- possession of a valid student ID card (for pupils/students up to 26 years of age)

- a confirmed statement of full-time employment for at least the minimum wage

- having a business activity
