The Dashboard page presents all figures to allow you to understand how your ads are doing.
The first row shows the total amount of money spent in ads, the total number of impressions, the total number of clicks and the total number of conversions.
The graph below shows the evolution of impressions, clicks and conversions over time.
The third row gives you the main metrics values to evaluate your ads performance: CPM (cost per mille, i.e. per thousand impressions), CPC (cost per click), CPA (cost per action, i.e. cost per conversion) and CTR (click-through rate).
