HOW-TO: exclude subdomain from my visits AND count only visits from specific URLs

General questions
1

Hello everyone,

Real newbee on Matomo here. But I didn’t see the answer in the FAQ nor in the Kn.Base.

Basically I want to do 2 things separately

  1. Exclude traffic from subdomains that are driving traffic from internal tools (newsletter, intranet, internal messenger…)
    Example: messenger.mywebsite.com/ ; intranet.mywebsite.com

  2. Count traffic from a specific page group only.
    Example: mywebsite.com/ThisGroupPage/*

I would really appreciate help from Matomo veterans :military_helmet: :folded_hands:
