Does account time zone affect ad delivery?

Time zones do not directly affect distribution, but strongly affect schedule , cost reporting and optimization of distribution time according to user behavior. If the time zone is set incorrectly, ads may run off prime time, data may be difficult to read and optimization may be ineffective. It is best to set the time zone to coincide with the target market.

Timezone does not kill the campaign, but if it does not match the audience's operating hours, it is easy to burn the budget during off hours. Some setups such as dayparting and hourly reports all follow the acc timezone, so choosing the wrong one from the beginning will make it difficult to scale correctly. Always align timezone with geo to read data close to reality and keep ROI stable.

Time zones will affect how you analyze and track your ads so you can optimize your ads.
