" For example, a user on my-site.com goes to your-site.com, and then returns to my-site.com. If you do not exclude your-site.com as a referring domain, two sessions are counted, one for each arrival at my-site.com. If, however, you exclude referrals from your-site.com, the second arrival to my-site.com does not trigger a new session, and only one session is counted."
Does this apply ONLY if your-site.com has GA tags of my-site.com?
Hi Shashank S,
"Does this apply ONLY if your-site.com has GA tags of my-site.com?"
No, you can still make use of the referral exclusion list providing you are using Universal google analytics instead of classic.
