Blacklist
Blacklist is a list of advertising sites, platforms, or apps where ads perform poorly and fail to generate target actions.
A blacklist is created manually by the advertiser based on statistics such as clicks, conversions, retention, and traffic quality.
Why a blacklist is needed
- reduce budget waste
- filter out fraudulent or low-quality traffic
- increase conversions and ROI
- improve audience quality
What is usually added to a blacklist
- sites with high CTR but zero conversions
- sources with bot traffic
- platforms with low session duration
- apps with suspicious user behavior
Blacklist in simple terms
It’s a “block list” of sites or apps where ads don’t work, so they are disabled to avoid wasting money.
