When you pick an audience by its name, you are guessing. "Vietnamese in USA" sounds like people in America. "Founders" sounds like men. The profile data often agrees, but when it does not, the difference decides whether a campaign works.

Here are five cases from our audience reviews where the data corrected the name.

1. The US community that lives in Vietnam

The Vietnamese in USA group is called "Vietnamese Community in the USA". Of its top ten member locations, nine are in Vietnam, led by Ho Chi Minh City with 2,794 profiles. Only one US location makes the list: Orange County, with 126. The audience is not living in America; it is planning for America. That points to study abroad, immigration and remittance offers, not local US services.

2. The Australia group that became an exam library

The IELTS Forecast Group is listed in our system under its original name, a Vietnamese-in-Australia community. On Facebook it now shares IELTS forecasts. The 12,735 profiles fit the new purpose: 65% women and 55.6% aged 18–30 among profiles with a birthday, the profile of students preparing to study abroad.

3. The founder group led by Canada

The $100M Mastery Club is an unofficial community about growing a business. You might expect a US audience. The data shows Canada leading with 248 identified members across four entries, and Vietnam second with 101 in Ho Chi Minh City and Hanoi. For a service provider, that is a market-entry list, not a domestic one.

4. The university page where women lead

The Columbia University fanpage audience is 43.8% women and 35.4% men among profiles with a stated gender, and one in three profiles is in the New York tri-state area. The page reads as global; the audience behaves as local.

5. The beauty page that covers the whole country

The HannahOlala page is run by a creator who grew up in the US. Its audience is firmly Vietnamese and nationwide: Ho Chi Minh City and Hanoi lead, but the top ten locations together hold only 52% of the list, with the rest spread across the country.

The lesson

  • Read the name as a hypothesis.
  • Check location and gender before writing a single ad.
  • Let the data choose the offer: the same community can be right for one industry and wrong for another.
