Can I advertise my own coop link in Harvest Traffic Coop?

"Can I advertise my own coop link in Harvest Traffic Coop?"

No, you can't advertise your coop link (that earns you coop credits) in the same coop as the one where you are trying to earn credits. It would be a little like surfing in a traffic exchange and seeing your own site in surf - you would lose a credit each time you saw it but you would also gain a credit from surfing to see it.

However, you can add any of the promo material from the Promote - Promo Tools page though, there is an affiliate link and splashpages there. But if you promote your coop link in various traffic sources, the top frame has your referral link too.
