What counters and services do you usually put on the Landing Page?

Question

CRM

Created a company landing page on wordpress, collecting applications for services. The company is focused on b2b.
Question? What do you usually put on your landings, besides Google analytics and Yandex metrics?
What services do you use, integrating them with the site (telephony, chats, application forms, crm systems).
I am taking the first steps in this area and the set of tools used by experienced people is very interesting.

Answer 1

Answer 2

Try to ask yourself the question "why" and you will find the answer yourself.
Having services for the sake of having them is the most useless thing to do. And given that various services can interfere with the performance of the site due to errors, it is also harmful.
