In X Ads, a bid cap acts as a limit during the real-time auction for ad placement. Here’s how it works:
- Advertiser Sets Cap: You determine the maximum price for an engagement (e.g., click, retweet).
- Auction Process: X Ads enters your bid into auctions for the targeted audience, but it never exceeds your cap.
- Cost Control: If the auction price goes above your bid cap, your ad won’t compete, ensuring budget efficiency.
Bid caps are especially useful for maintaining ROI in performance-driven campaigns.
