Setting impression criteria
Image ads are only shown in ad networks.
- Ad networks
In ad networks, keywords ensure that your ads are served on sites with content that matches your keywords.
Additionally, ads in networks can be served based on retargeting lists. This means that ads are only shown to selected users, such as people who performed specific actions on the website.
You can also target your ads in ad networks based on the users' short-term interests and habits: you can show relevant ads to people who are looking for your products or services now or have recently searched for them. You can use interests and habits as separate impression criteria or combine them with keywords to increase your reach.
