Questions about Direct.
Does the number of keywords in a group affect the average ad price?
What parameters should be taken into account in order to make an ad more economically?

Answer 1

The exact amount doesn't matter. Affects the quality of the ad!
You can make an announcement more economically by experimenting with texts, filling out business cards, creating quick links, etc.

Answer 2

Quantity affects, but indirectly. Will explain.
Cutting off low-click ads, as well as ads with low conversion to the application (if you track goals) will allow you to significantly reduce the average ad price for 2 reasons
: because The bid for a position in the SERP is calculated as CTR*$, where $ is a sufficient bid to occupy the desired position, but not more than the maximum bid you set for the keyword. Those. by removing such keywords, you will get rid of both expensive clicks and irrelevant traffic; the same applies to keywords that are clicked, but do not lead to conversion on the site into an application, purchase, etc. - they just "drain" the budget;
b) don't be afraid to lose "reach" because when you remove all the crap, your effective ads will generate more clicks for the same money, so you compensate by taking away the share of these keywords from your competitors.
In other words, if, for example, you are selling ladders for summer cottages, think about whether you need the keyword "cottage construction", if you do not have Gazprom, of course. And even better - calculate the ROI and see for yourself!
Briefly:
1. Try setting goals.
2. Merge keywords with low CTR and low or no closing goals.
