HilltopAds, one of the best ad networks for advertisers, has introduced Smart CPM for Popunder campaigns, an automated bidding model designed to help advertisers manage a smarter way to buy traffic and control their budget. With this automated bidding model, advertisers can win more impressions at lower prices while setting clear CPM limits to protect their spend.

Smart CPM automatically adjusts bids dynamically in real time based on live auction data. Instead of always paying your maximum CPM, you only pay what’s needed to win each impression. This approach can improve cost efficiency, especially in volatile inventory environments.

The feature is available across all Popunder campaigns within the HilltopAds platform.

The addition of Smart CPM fits into a broader shift toward automation and data-driven optimization in ad operations. Features like advanced targeting, postback tracking, and micro-conversion analysis are now standard for teams seeking to reduce manual intervention and improve campaign efficiency. Automated bidding models such as Smart CPM are particularly relevant for practitioners managing multiple campaigns or working within strict budget parameters.
