Which option in Facebook Ads Manager is essential for managing your spending?

The essential option for managing your spending in Facebook Ads Manager is the spending limit settings. This feature allows advertisers to set specific limits on how much they are willing to spend on their advertising campaigns. By utilizing spending limits, you can control your budget effectively, ensuring that you do not exceed the allocated amount for the duration of your ads. This is crucial for maintaining financial oversight and for making sure that advertising expenses stay within your predetermined budget, ultimately helping you manage your marketing costs efficiently.

While time zone selection helps schedule the timing of your ads, ad creation tools are focused on designing and implementing your campaigns, and post insights provide analytics to evaluate performance, none of these options directly influence spending in the way that spending limit settings do.
