I have been stuck at this and applied atleast 10 different filters reading various guidelines in google analytics forum, blogs etc. But nothing really works. If somebody do have a practical experience in implementation of same kindly share. What i need to do is there are some traffic channels shown in my website GA profile like kin.naver.com / referral m.kin.naver.com / referral I need to filter these so as they never show up in my traffic count.... This seems to be easy but issue is because of subdomain (kin. , m. ..)
