The Analytics tab will let you view how your project is doing as well as a bit more information on how you set up your project.
In the top left corner, you can view your target number, number of qualified responses, number of total responses, as well as the number of participants in each status.
In the top right corner, you can view how often the project has been viewed and clicked, as well as the click-through rate. Typically, a low CTR means that the incentive is too low, your screener is too long, or you're asking for too much time with these participants.
In the bottom right, you can view the current incentive as well as the options for changing the incentive.
