Results: Our Facebook advertisement delivered 130,129 impressions, resulting in over 2000 clicks at an overall cost of Aus {\$}918 (Aus {\$}0.44 per click). Web-based project information was accessed by 493 women. Of these, 462 women completed the screening survey, and 437 (437/463, 95{\%}) women were eligible. A total of 322 young women participated in Surveys 1 and 2 (74{\%} response rate), and 284 women participated in Survey 3 (88{\%} retention rate), with an advertising cost of Aus {\$}2.85 per consenting participant. Conclusions: Facebook proved to be a quick, effective, and cost-efficient tool for recruiting young Australian women into a study that was investigating contraceptive preferences. However, Web-based recruitment may result in sociodemographic biases. Further research is required to evaluate whether Facebook is suitable for recruiting older study populations.
