You are charged in Google Ads under the following conditions:
1. First $1 Worth of Clicks: When you accumulate your first $1 in click revenue.
2. Additional Clicks: When you accumulate additional clicks that meet or exceed your credit limit.
3. Balance Due: If you have a balance due from the previous month and haven’t reached your credit limit, you will be billed on the third day of the month.
Additionally, for campaigns using a vCPM (viewable cost per thousand impressions) model, such as Sponsored Display and Sponsored Brands, you will be charged per 1,000 impressions instead of clicks.
