Which reporting metric, unique to the Yahoo Gemini platform, directly reflects the percentage of eligible ad opportunities that were *actuallywon during real-time bidding?

The reporting metric that directly reflects the percentage of eligible ad opportunities that were actually won during real-time bidding on the Yahoo Gemini platform is called 'Win Rate'. Win Rate represents the proportion of times your bid was successful in the ad auction compared to the total number of times your ad was eligible to participate in the auction. Real-time bidding (RTB) is an auction process where advertisers bid on individual ad impressions in real-time. A high Win Rate indicates that your bids are competitive and relevant to the target audience, while a low Win Rate suggests that your bids may be too low or your targeting may be too narrow. For example, if your campaign had 1000 eligible ad opportunities and your ads were displayed 200 times, your Win Rate would be 20%. A low win rate often suggests that you need to increase your bid, broaden your targeting, or improve your ad quality to become more competitive in the auction. Monitoring the Win Rate helps advertisers understand how effectively their campaigns are competing in the real-time bidding environment and make necessary adjustments to optimize performance. It is distinct from metrics like impression share, which reflects the percentage of potential impressions you captured, and click-through rate, which measures user engagement with the ad.
