Is it possible to write a script for registering visitors who follow a link to a site?

Question

User identification

A script is required to register site visitors
Step-by-step description:
- the user follows a short google link with a promotion (mail, banner, social networks, sms, viber)
- goes to the link of site No. 1, then redirects to site No. 2, where he surfs site page.
- script (can also be hosted on the hosting of site No. 2, but autonomy is better) captures the time of visiting from the link and the user's activity on site No. 2 (the time of the transition and the pages that he views, imitates his interest in specific pages, indicating the time spent on them). More precisely, the script registers all users who have visited this site, but selects those who have visited the specified link.
- access to the "script" posted on site No. 2 for up-to-date information and its autonomous reporting of statistics after each change with sending a report to site No. 1 in the form of lists
Question:
1. Is it possible to fulfill this TOR?
2. How detailed information can be obtained about the visitor?
