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. To view this data, go to the Reports Wizard.
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.
