You don't want to place your preprint just anywhere. The National Institutes of health provides some guidance for selecting a preprint repository.
Interim research products rely on repositories to make them public. The repository market is growing rapidly, and in many scientific disciplines, norms for interim research products are still evolving.
The NIH would like to ensure that practices for interim products facilitate the impact, measurement and the integrity of the scientific record. Specifically, the NIH strongly encourages interim research products arising from NIH funds to be deposited in repositories that ensure:
