How do i run website targeted campaigns?

Steps to apply site targeting

Set up campaign --> Capture the Source id / Site ids --> Use target option in site id report to Target specific site id's --> Pause all other sources like channels, RON etc and let only site ids live.

this will insure you get traffic from only selected sites as mentioned, but this will block any fresh sources, in case you want to expand and increase traffic. So this is suggested for campaigns which are live for over couple of months and have all network exposure.

In case of any doubts, feel free to contact your account manager to fix this for you.
