A campaign's targeting must be edited at the adset level. Edit the audience targeting settings for one or more adsets in a campaign.
To edit a campaign's targeting
- Click Your campaigns on the main navigation bar, click Search a campaign, and then select the campaign.
- Click the All ads tab. Here you will see a list of all your adsets.
- Click Adset Actions below the adset you want to change the targeting for, and then select Edit target.
- Make your changes to the targeting on the adset, and then click Proceed in the bottom-right corner.
- If there is more than one adset with the same targeting settings you have just changed, you can choose to edit them all, or only the one adset.
