How to recruit user test participants?
There are a number of new tools available to conduct automated, oftentimes remote user testing (Treejack, Chalkmark, etc.). However, if you are building a product from scratch how do you get targeted audience members (such as those that might only be interested in buying mommy / baby products, or outdoor aficianados) to participate in a user testing session? Do you actively recruit online, or add a 'Feedback' button on the site? Ask friends and family? What if you want to then segment by age group?
I am looking for some best practices for this specific use-case (in-person and focused on a specific demographic).
