Frequency capping limits the number of times your ads appear to the same unique user on the Google Content Network. It doesn't apply to the Search Network.
If you turn on frequency capping for a campaign, you specify a limit to the number of impressions you will allow per day, per week, or per month for an individual user. You also choose whether the cap applies to each ad, ad group, or campaign.
To specify a frequency cap, follow these steps:
- Sign in to your AdWords account at https://adwords.google.com.
- Click the name of the campaign you wish to edit on the "All Online Campaigns" page.
- Select the Settings tab.
- Under "Advanced settings," click Edit next to "Frequency capping."
- Enter the number of impressions. The value must be a whole number (such as 100, not 100.5).
- Select a time interval (per day, per week, or per month) and a level (per ad group, per ad, or for this campaign).
- Click Save.
- Repeat this process for any additional campaigns.
