Custom segments help you reach your ideal audience by entering relevant keywords, URLs and apps.
You can set up a custom segment in your Display, Discovery, Gmail and Video campaigns by adding specific keywords, URLs and apps related to your product or service. Google Ads will review these additions to ensure that they abide by advertising policies, then show ads to people with these interests or purchase intentions on pages, apps and videos. Learn more about audience targeting.
Note:
Estimate settings default to all campaign types, language and location. After you edit 'Audience insights' for the custom segments and save it, on re-opening the segment, the previous settings may reappear. These settings aren't saved and they don't affect the performance of the segment.
How custom segments work
Custom segments automatically choose the right audience to best fit the needs of your campaign. Based on your campaign goals and bidding strategy, the system will interpret all of those signals and choose an audience that is focused on one of the following:
- Reach
- Consideration
- Performance
Example
Rather than reaching the Sports Fans affinity segment, a running shoe company may want to reach Avid Marathon Runners instead. With custom segments, the shoe company can define this segment by entering keywords, URLs and apps:
- Entering interests like '5K runs', 'triathlon athlete' or 'long distance runner'.
- Using URLs of websites with content about running, training schedules, marathon nutrition and other marathon themes.
- Entering apps in the Health & Fitness category that an Avid Marathon Runner may likely be interested in like Google Fit
Custom segment inputs
| Reach people based on | Inputs | Audience type |
| Interest or behaviours | Keywords |
Enter interests, in the form of keywords or phrases, that represent your ideal customer. Your ads will reach people who are likely to be interested in or have purchase intent for your keywords based on their behaviour and activities, such as apps that they use or the type of content that they browse or search for online. When you enter interests or behaviours, you have a choice of how Google should interpret the inputs:
|
| People who browse websites similar to | URL |
Enter website addresses (URLs) that your ideal customer might visit. Your ads will reach people who browse websites similar to the URLs you enter. Note: this doesn't mean your ads will show on those URLs. |
| People who use apps similar to | Apps |
Enter the names of apps that you think your ideal customer might use. Your ads will reach people who download and use apps similar to the ones you enter. Note: This doesn’t mean that your ads will show on those apps. |
