If you come across an online survey or focus group you’ve never heard of, do your research. Consult trusted websites to see if these groups are recommended. Run search engine queries and consult user review sites like Trustpilot to learn about others’ experiences with these survey sites. Proceed with caution, especially when asked to provide financial information. Some legitimate services may need your bank info to pay you, but many companies let you accept payment via check or payment app.
