The Bid/Imp Ratios section provides additional insight into Campaign bidding efficiency by showing how frequently Eligible Requests progress to Bids and how often Bids result in Impressions.

Use the Time Frame filter to view data for 6 hours, 12 hours, 24 hours, or 48 hours. Data is displayed in hourly increments.

Available ratios include:

• Imps to Bids Ratio: Shows how frequently submitted Bids result in won Impressions.
  • A higher ratio indicates that a larger share of Bids are winning.
  • A lower ratio may indicate lower bid competitiveness, stronger auction competition, or Deal/inventory conditions.
• Bids to Eligible Bids Ratio: Shows how frequently the platform submits a Bid after a request passes eligibility.
  • A higher ratio indicates that the Campaign is bidding on a larger share of Eligible Requests.
  • A lower ratio may indicate additional serving restrictions such as budget, pacing, Creative eligibility, Frequency & Recency, or bid requirements.

Hover over either chart to view the timestamp and ratio value for a specific point in time.

Use these ratios together with Bid Data to identify whether delivery is being restricted between Eligible Requests and Bids or between Bids and Impressions.
