Why brand bidding is so expensive

An affiliate bidding on your brand competes with your own brand campaign. Your CPC rises, and the user who was already looking for you arrives via an affiliate link — you pay click and commission for an existing contact. Similar patterns arise with cookie stuffing, toolbar overwriting or leaked exclusive codes.

Continuous monitoring – Brand ad monitoring across regions and times, anomaly detection on click-to-sale times.
