I have install coop in all my websites, does it only track impression from my site that registered on coop, or it tracking all impression from my all sites..?
You have to have one account for each domain. Valiadate only checks that one domain. But you can have the files on just one domain, if you know how to get other domains to grab them. For example I use LWP::Simple in perl to get the info from the script/log on another domain, on the same server.
So The weight of validation number, generate only from impression of my site that registered on coop..??? I my case above, does it brake the rule of TOS of Co-op ad network ..?
