Blacklisting explained

Cut the leaks first

Blacklisting means blocking specific sources – the source IDs that spend without converting. It's usually the very first optimization a campaign needs, because a handful of bad sources can quietly drain a budget while contributing nothing. Removing them is faster and often more impactful than any creative or bid change.

On FroggyAds you read performance down to the source ID, blacklist the wasters, and watch budget concentrate on what's left. Used alongside whitelists, SmartCPC and Adscore, blacklisting keeps campaigns lean as they grow. It's the simplest high-leverage move in media buying – and it starts from $50.
