All Facebook campaigns will run with campaign budget optimisation as of September.

Facebook announced on Wednesday that, starting in September, new and existing campaigns will be migrated to Facebook’s automated campaign budget allocation system that optimises the campaign budget across an advertiser’s ad sets. This means Facebook advertisers will no longer be able to define budgets at the ad set level.

Why you should care?
Facebook advertisers are currently able to set budgets by ad set within a campaign, but, starting in September, when ad campaigns migrate to campaign budget optimisation, advertisers will only be able to set budgets on a campaign level.

The change will apply to existing campaigns as well, so if you have long-term or evergreen campaigns with specific budgets and performance expectations at the ad set-level, start thinking about what this change will mean for those efforts. Take the same considerations for any new campaigns set to run beyond September.

The goal, says Facebook, is to give advertisers better results at a lower cost by distributing a campaign budget based on the best performing ads, but the move takes a certain amount of control away from advertisers.

“You’ll have the ability to set one central campaign budget to optimise across ad sets, and we’ll automatically and continuously distribute the budget in real-time to your top performing ad sets,” said the company.

It also means advertisers will have to have faith that Facebook’s automated budget allocations will deliver efficient results.

More on the news
Facebook says in the help page on campaign budget optimisation that advertisers will need to gauge the system’s success “based on the total number of results for your campaign and the average cost per optimisation event at the campaign level” rather than at ad set-level results.
Advertisers will not have access to metrics such as the total number of opportunities for each ad set or how much each result costs when campaign budget optimisation is running.
Facebook said BuzzFeed has tested the budget optimisation tool for its content ads and achieved greater cost efficiencies and easier budget management, along with more video ad views and clicks.
