Some of these challenges include geographical barriers, insufficient time and financial resources, and perceived HIV-related stigma. Objective: This paper describes the methodology of a recruitment approach that capitalized on existing online social media venues and other Internet resources in an attempt to overcome some of these barriers to research recruitment and retention. Methods: From May through August 2013, a campaign approach using a combination of online social media, non-financial incentives, and Web-based survey software was implemented to advertise, recruit, and retain participants, and collect data for a survey study with a limited budget. Results: Approximately US {\$}5,000 was spent with a research staff designated at 20{\%} of full-time effort, yielding 2034 survey clicks, 1404 of which met the inclusion criteria and initiated the survey, for an average cost of US {\$}3.56 per survey initiation. A total of 1221 individuals completed the survey, yielding 86.97{\%} retention. Conclusions: These data indicate that online recruitment is a feasible and efficient tool that can be further enhanced by sophisticated online data collection software and the addition of non-financial incentives.
