For those dating sites who can advertise on Facebook, they will now be able to target the 92m expats who are on the social network.
The new targeting feature will let brands reach expats living in a certain country, as well as expats from a certain country.
For example, brands could target expats living in Brazil, or people born in Brazil living abroad.
One dating company that could benefit from targeting such people is Tinder – who recently launched their premium service which lets you change your location to swipe through matches in a different country.
Tinder, and other dating apps and sites, could have success targeting expats who might often travel home for holidays to see friends and family.
Facebook gave the example of Etihad Airways using the feature to target the 27m Hindus on Facebook living outside India, many of whom would be travelling home before Diwali.
They said using this targeting feature, Eithad reached 536,00 Indian expats living in the Middle East, leading to 700 bookings and a 50X return on investment.
Nationality-specific targeting is currently available for people from Brazil, Indonesia, China, South Africa and India.
The expat targeting is now available worldwide in all Facebook ads interfaces, including the API.
