What is eCPM and why is it fluctuating?
The effective cost per 1000 impressions, or eCPM, allows you to understand how much money you have made in the past per thousand views and the variety of ads that have shown in your game. Our money comes from advertisers in different forms. Sometimes they buy per view, per click or per action of the ad in your game. The various ads that show will be a mix of these types at different prices. Effective CPM doesn’t represent your earnings – rather, it’s calculated by dividing your earnings by number of page impressions, then multiplying by 1000. If you made $1.00 over 1,000 impressions then your eCPM would be $1.00. If you made $1.00 over 2,000 impressions your eCPM would be $0.50. Your eCPM will fluctuate throughout the day based on your traffic and our ad inventory. The CPM for a specific ad is basically a fixed price, and depending on which ads are shown and what the advertiser is paying, this value will fluctuate. Your eCPM goes up if you get more impressions of higher value CPM ads,
