Beginning Monday, users who dont clearly link their Facebook and Instagram accounts in Facebooks Accounts Center will be dealt with as 2 different individuals.
The privacy-centric course correction could affect measurement and estimates for audience reach for marketers.
In the past, Facebook served ads throughout a users Facebook and Instagram accounts based upon presumptions that linked one account to another. Its not likely users realized this was taking place.
If the very same email address managed a Facebook and Instagram account, the two would be connected internally and thought about one user for advertisements preparing and measurement purposes.
Now only users who link their main Facebook and Instagram accounts in Accounts Center as a single person will be thought about the very same user.
It makes good sense for Facebook to start honoring this option for advertisement purposes proactively instead of getting called out down the line for connecting accounts without a users understanding.

Facebook set the phase for this change in September when it presented a single sign-on center dubbed Accounts Center, which lets users manage their settings across apps. Users who connect their accounts in Accounts Center, for example, can more easily share stories and posts in between Facebook and Instagram.
When Accounts Center first introduced, its specified purpose was to make Facebook, Instagram and Messenger more interoperable for users.
Now, Facebook will begin to use preferences from the Accounts Center– such as whether accounts throughout its family of apps are linked or unlinked– to notify the metrics advertisers use for planning and campaign measurement.
In a post, Graham Mudd, Facebooks VP of item marketing for ads, wrote that the upgrade “aligns with trends of using individuals more control over how their info is used for advertisements and is consistent with evolving marketing, personal privacy and regulative environments.”
Facebook stated advertisers probably wont experience too much of influence on their campaign reach. Mudd did keep in mind that keeping unlinked account holders separate for marketing purposes might cause marketers to see increases in their pre-campaign estimates, including approximated audience size.
Mentioning approximated audience size, just recently Facebook revealed plans to display a variety instead of a specific number when revealing advertisers the potential reach of a campaign. Facebook also rebranded its “possible reach” metric to “estimated audience size.”
The relocation was partly to develop more consistency between Facebook and how other platforms in the advertisement industry present their reach quotes, but it was likely likewise related to an ongoing suit over how Facebook determines potential reach.
And if there is an effect on estimated audience size as an outcome of Facebook not counting unlinked accounts as one person, Facebooks decision to share a range rather than precise number suggests advertisers wont have the ability to complain if theres irregularity in the counts.
