We currently offer ad positions on our network in both niche
specific and run-of-network. Pricing for each ad position
across our network is calculated based on the revenue per
impression (RPM) and revenue per click (RPC). On a weekly
and monthly basis we calculate each position's RPM and RPC
in order to maintain consistency and limit position
advertisers. This insures that we don't flood a position
with advertisers reducing the overall RPM and RPC.
