The formula for calculating the ad show rate is:

Ad show rate = (Number of ad impressions / Number of users) x 100

For example, if an ad is shown to 100 users and it is clicked on 10 times, the ad show rate would be calculated as follows:

Ad show rate = (10 / 100) x 100 = 10%

It’s important to note that the ad show rate is just one metric that can be used to measure the effectiveness of advertising in an app. Other metrics that may be relevant include the click-through rate (CTR), the cost per thousand impressions (CPM), and the revenue per thousand impressions (RPM). By looking at a combination of these metrics, you can get a more complete picture of how well your ads are performing and identify areas for improvement.
