Facebook has a new ad-level option: “Optimize text per person”. Now the social network can swap the main text, title or description of the ad.
How it works: Facebook algorithms keep track of which ad element (body text, headline or description) is more likely to be responded to by a particular user. After that, the program will put this text in place of the title in the ad.

The new option is currently only available to some advertisers. To the request from SocialMediaToday about the timing of the launch of the option in all accounts, a response from the social network team has not yet been received.
