Why are ads not showing or low efficiency?

Question

Yandex.Direct

Hello.
I throw in 1000 rubles every one and a half to two weeks.
Strategy - Optimization of clicks (previously called the average cost of a click)
Keep the price of a click 1.50 rubles. on average per week
I can't understand why the ads are either in the top, or in the footer, or not in the search results. Weds are spent slowly - there is no demand for search queries? In general, some kind of instability in everything. I don't understand what I'm doing wrong.
Ads are set up well (NCZ, binding to regions / cities), I assume that the error is in something else.

Answer 1

Specify the regions in which you are located, the established budgets for advertising campaigns. Do I understand correctly what search campaigns mean?
The most likely reason is that the campaign budget is too low and the bid is too low. To confirm this, please tell us whether the established budget and cost limit is being met?
