Tell me what to do with the budget. I was faced with the fact that good ads get a high price per click because of the budget. And I do not increase and immediately creates an ad with a big budget. Example. I have an ad group where cpc 13 cents ( ctr 10%). I am copying the SAME ad group reducing the budget four times - cpc 2-3 cents. ( ctr. 5%). Strategy - auto-bid. In manual rate differences are not as great, but the dynamics are the same.
Explain to me how to work better with the budget? I know that it is impossible to dramatically increase the existing ads. But I created a new. Don't understand what it is.
