Craigslist.org, an online community of local classifieds and forums, was founded by Craig Newmark in 1995. Incorporated as a for-profit in 1999, the website retains the .org domain because, as the website's factsheet explains, "It symbolizes the relatively non-commercial nature, public service mission, and non-corporate culture of craigslist."
A person utilizing Craigslist to identify opportunities to participate in a paid study or survey may search in several different categories.
Navigate to craigslist.org.
Select a location in which to search: Look on the right side of the screen. Click on your state, then choose the city nearest to you.
Click on "ETC" near the bottom of the "jobs" column on the right side of the page.
Read the resulting "SCAM ALERT" page, then click on "Continue to job postings."
Type your search term — such as "paid survey," "clinical study" or simply "study" — in the "search for" window and click on "Search."
Click on each resulting link.
Follow the same procedure in the "medical / health" and "nonprofit" categories under "jobs."
