What is river sampling?

River sampling is a non-probability method of sampling that seeks to recruit web users while they browse the internet or engage with mobile applications. Potential respondents are presented with survey links or ads on websites or apps then screened and if successful, forwarded on to complete a survey.

River sampling is fast, anonymous, and engages potential respondents in their native environments without human interference or pre-recruitment influences.
