Mini-case "Target call Yandex saved the planet!"

Problem
44 active advertising campaigns in Yandex.Direct. Most of them had zero conversions in the last few months in electronic commerce, but actively “ate” significant budgets.
These campaigns were planned to be turned off as unprofitable, but at the last moment we assumed that they could give calls and, as a result, orders.

Task:
Find out: do they bring calls?
')
Solutions:
Calltouch is expensive. Long sessions (people hang for 20 minutes over the goods) and a lot of traffic. Estimated cost of the service amounted to more than 100,000 rubles per month.
The target call of Yandex (CZ) turned out to be an excellent and cheap way out of the situation!

Method Description:
It was purchased 12 rooms CH for a month. Their cost was 3 960 rubles.

The numbers in turn were attached to “bad” campaigns, which for months had eaten huge amounts of money and did not bring conversions at all.

If during the first 3-4 days the campaign showed calls, it was recognized to be working, and the number was transferred to the next advertising campaign.
No long measurements, three days - and connect the next one.
Thus, all the "dead" RKs were checked in a circle.

Result:
Shock! We realized that almost all these campaigns gave a daily mass of calls, without bringing transactions in electronic commerce. And we almost turned them off.

Apparently, people chose goods in the store, and then they called the operator with clarification and completed the order by phone.

Conclusion:
Only 4 thousand rubles and 2 weeks of time completely turned over the work of the source.

Chip method:
The revolution is that we have connected strictly "bad" campaigns.
Good RK did not engage at all, with them, and so everything is in order.

Lack of method:
Not applicable to other sites besides Yandex.Direct.
Campaign granularity is available only for Direct. Google measures the whole thing, which means it doesn't make sense.

Do not rush to disable the "bad" campaigns in Direct. Perhaps they give calls, but you do not suspect it!
