Manage Lookalike Audience
To manage a Lookalike Audience please go to the "Audience" management page under "Assets". 

The following actions are available for you to manage your audience:

Edit

You can edit the name of Lookalike Audience. 

Auto-refresh Weekly

Lookalike Audience applied in a running ad group will be auto-refreshed on a weekly basis.
You can find the latest update time in the column Availability on Audiences Page.

Manual-refresh

You can manually refresh if necessary. But, we do not recommend frequent manual refreshes, since it won't impact the audience size. Your Lookalike audience will be unable to refresh if you manually refresh the audience too frequently. Manual-refresh works for all types of Lookalike Audiences. After refreshing, your most recent update time will be displayed.

Note: Lookalike Audience that have not been manually-refreshed can be auto-refreshed or manual refreshed when they meet your criteria. But if your source Audience is ever deleted, the Lookalike Audience created from it will be unable to refresh. If your Lookalike Audience is "Refresh Unavailable", we recommend recreating your Lookalike Audience.

Apply Audiences

You can connect an audience with an ad group by clicking "Apply to Ad Groups" on the "Audience Management" page or on "Ad Group Creation" page.

In the process of creating an ad group, you can select to include or exclude multiple audiences in the same ad group, however the same audience can't be included and excluded at the same time. When you include or exclude two different audiences, the duplicate parts will be excluded.

Note:
  • Apply to ad groups: Applying one available audience to multiple ad groups is supported, but applying multiple audiences to multiple ad groups is not supported.
  • Duplicate checking logic: Audience already in use cannot be added again, but you can change the "Include" or "Exclude" status.
    • For example, you have set audience A to be included in ad groups 1 and 2. If you now want to set audience A to be excluded in ad groups 1 and 2, you will be prompted to confirm the change of "include" to "exclude".

Share

You can share your audience to your own related business account.

Omit

You can omit the Lookalike Audience you don't need. If the audience has been connected to an ad group, you must disconnect the audience with the ad group before deleting the audience.
