Feasibility is an estimate of how many completed survey responses are expected. This estimate is calculated by the following things:
Cost per Complete
Length of survey
Time in field
Feasibility estimate can be found underneath pricing when all of the above criteria is filled out.
The longer a project has in field, the more completes the project will be able to pick up. For example- above is a 5 day feasibility estimate and below is a 10 day feasibility estimate.
Tips to improve your feasibility:
Raise price- the cost/complete directly determines how much the respondent is rewarded. Respondents are picking from a wide variety of surveys, so giving a higher incentive will make your survey more competitive and increase feasibility
Expand audience- if possible, limit your target group to allow more people to take the survey. For example, if you are targeting specific county consider allowing surrounding counties or the entire state to take the survey
Shorten the survey- since most of the respondents are taking the survey on their mobile device, having a long survey will discourage respondents from picking your survey. For tips on making your survey shorter, see here.
Improving incidence- This is similar to expanding your audience, but will involve your actual survey. For example, if your survey disqualifies everyone doesn't own a dog- then maybe you could consider allowing anyone who owns a pet. Making your survey accessible to a broader audience will increase feasibility.
