Fill Rate vs Competitive Factor

What is the difference between fill rate and competitive factor?

Fill rate is the percentage of ad requests that are filled with an ad. It is calculated by the formula:

Fill Rate = (Fills ÷ Sent Requests) × 100%

Competitive Factor shows the fill rate distribution for each ad network. It indicates what share of the total fills each network contributes. This helps you understand which ad networks are performing well within your mediation stack and which ones are winning the competition for ad impressions.
