What is Facebook CBO?

Facebook Campaign Budget Optimization (CBO) is a method of controlling and optimizing advertising budgets in your Facebook campaigns.

Instead of having an individual budget for each ad set, you set a total overall budget on the campaign level. Once you set this then Facebook uses its AI to decide how much to spend on each audience for the best returns.

Below is a diagram from Facebook’s post introducing CBO, which shows the difference of an ad campaign with and without using CBO.

Businesses can also set bid caps and spend limits for each ad set in addition to setting a daily or lifetime campaign budget.

This software allows advertisers to maximize their budget and extract the greatest value from their campaigns. CBO operates in real-time to help lower cost per result and increase return on ad spend (ROAS).

Of course, you know that at Optily we’re big fans of increasing ROAS!

How do you set up Facebook CBO?

Thankfully, Facebook CBO is integrated into the Facebook Ads Manager, making the process of setting up a campaign optimization budget for your business simple. 

Follow these easy steps to get set up:

➡️ Navigate to Facebook Ads Manager.

➡️ Click the blue Create New Campaign button.

➡️Set up a Facebook Ad Campaign as usual. If you need a refresher on how to do this check out our blog on Meta (Facebook) Ads Manager Made Simple.

That’s it–it’s that simple!
