The next important report for analyzing YAN is the traffic report by time of day:
In this report, we select the goal(s) that are responsible for receiving an application, and pay attention to the number of conversions and the conversion rate:
Based on this report, we can set bid adjustments for specific time periods. And if our daily advertising budget is small, we can disable YAN ad serving during the hours when conversion rates are lowest.

And at the same time, we will increase conversions by adjusting rates during the hours when the odds are highest.
It's also worth noting that Yandex Direct often struggles to evenly distribute funds throughout the day in Yandex Advertising Network (YAN) campaigns, and it often happens that the daily budget is exhausted by lunchtime. Therefore, understanding which time periods bring the most benefit will allow us to more effectively allocate our daily budget.
The next thing to pay attention to is device statistics:
and on the conversion rate for the goal we need:
As with the reports discussed above, we can use the statistics we receive to make adjustments for specific devices. For example, if our website is poorly adapted for mobile devices and we see a high bounce rate and low conversion rate, we can disable mobile ads entirely.
