I created a campaign. Why no hits?
If the campaign does not receive impressions, you must perform the following steps:
Check the status of the advertising campaign.
Campaign status should be displayed as "active".
Check the status of promotional materials.
The status of promotional materials must be "active".
Check balance status.
Make sure you have funds in your account. Note! For ClickUnder format the balance must be more than 500 rubles.
Check targeting settings.
If there are few categories selected for delivery, a very narrow campaign target number and minimum bids are set, it is possible that the campaign will not receive impressions due to high competition on this traffic flow.
