Update to Our Pre-Campaign Estimates
Facebook provides pre-campaign estimates to help advertisers understand the estimated number of people who meet the targeting and ad placement criteria they select or how their ads may perform depending on those selections. These include Potential Reach, Estimated Daily Results and — if using interest categories — an estimate of the number of people who may have a particular interest.
In order to make the presentation of those pre-campaign estimates consistent, we are changing Potential Reach and interests into ranges instead of specific numbers, which is how Estimated Daily Results are already presented. Ranges are also in line with how pre-campaign estimates are presented on other platforms across the advertising industry. As part of this update, we will also be changing the name of Potential Reach to Estimated Audience Size.

For more information on Estimated Audience Size, visit our Help Center and Developer Blog. (Update on October 4, 2021 at 7:30AM PT: Added link to Developer Blog.)
