After your campaign has run for a while, you may choose to pause some ads that you can see aren't performing very well. Pausing adsets or ads have different effects on the budget of the campaign, just like they do on Facebook.
When ads within an adset are paused, their budget is redistributed automatically to the active ads within the campaign.
When an entire adset is paused, that budget is removed from the campaign.
It's a good idea therefore, to edit your campaign's budget, especially after pausing adsets, if you want to keep the campaign running with the amount you originally set for your campaign.
To edit a campaign's budget
- Navigate to the campaign's dashboard, and scroll down to the Campaign Details box.
- Click Edit (pencil icon) next to the budget.
- Make edits to the budget in this popup, and distribute the new budget across all adsets or across all active adsets.
- Click the Advanced tab to edit the budget of each individual adset in the campaign.
