Cost-per-thousand impressions (CPM) bidding
CPM bidding means that you pay based on the number of impressions (times that your ads are shown) that you receive on the Google Display Network. Starting this year, CPM bidding will be replaced by viewable CPM bidding. Existing CPM bids will eventually be transitioned to vCPM automatically. Find out more about using viewable CPM bids.
- CPM stands for cost-per-thousand impressions, so you pay for each set of a thousand views of your ad. You set CPM bids to tell Google how much you're willing to pay for that set of impressions.
- CPM bidding is best suited for advertisers who are focused on brand awareness. For advertisers whose main goal is sales or website traffic, CPC bidding (pay for each click on your ad) might be a better option.
- You set a maximum CPM (or "max CPM") bid as the highest amount that you're willing to pay for 1,000 views of your ad.
