How to evaluate the results of a display campaign

Impression statistics can help you evaluate the effectiveness of your ads. You can view ad campaign reports after your ads start displaying. In the side menu, select Statistics → Statistics for all campaigns. Go to the Report wizard tab.

For example, you can see what ad sizes are served most frequently. In the Cross sections block, select Ad № and Image size, in the Columns block, select the Impressions value.

For some parameters (such as audience reach), the system uses a statistical method to calculate metrics based on a sample of users. This lets you quickly get the parameter value for a large amount of data. Therefore, the reach displayed in statistics may not differ significantly from the true value.
