Keyword bidding is generally not available for affiliate marketers using push notification ads because push traffic operates differently from traditional search advertising. Unlike platforms like Google Ads, which serve intent-based ads triggered by user search queries, push ads are delivered based on user behavior, interests, or demographic targeting—not specific keywords. Push notification networks typically allow targeting by factors such as geo-location, device type, browser, and user interests. This broad targeting model is designed for mass reach rather than precise keyword intent. Additionally, keyword bidding would complicate the real-time delivery nature of push ads. Since users are not actively searching when they receive push notifications, keyword targeting becomes less relevant. Instead, success relies on creative optimization and audience segmentation rather than keyword strategies.
