I belong to almost all of the sites you listed and out of all the surveys I take I don’t qualify for 95% of them. I will spend 15 minutes with generic questions with them collecting information about me then when done they say I’m not eligible for the survey or they have reached the required amount of people for that research. I can understand the reaching the required amount of people but I would think I would qualify for at least 1 or 2. It’s really discouraging when you take all that time to do the survey and not even get any points for doing so!
Also, Panel Place makes for excellent user experience. It’s known that survey sites cannot make you rich; instead they are just for earning an extra income. As a result, users typically join different sites to earn extra bucks here and there. Keeping track of your activities in different platforms can be overwhelming. However, if you join Panel Place and connect all the survey panels you join with your Panel Place account, you’ll be able to see and manage all your activities in one place.
