✅ Plan Availability: All plans
- Studies with many segments that have a low number of participants take longer to fill.
- When setting up your screener, try to limit the number of segments (For example, no more than 4).
- Use the same segment to soft launch and fully launch the study.
- Below is an example of too many segments:
Screener Groups and Quotas
✅ Plan Availability: Corporate, Essentials, Professional, International, and Premium
- Screener groups are only available for studies with the Advanced Screener enabled.
- Studies with too many screener groups take longer to complete.
- Pro Tip: Keep screener groups at a minimum to speed up finding the right participants.
- Learn about screeners in this UserZoom Academy course.
Incidence Rate (Amount of disqualified participants)
Incidence Rate is the number of Completes divided by Completes + Disqualifies shown as a percentage.
Completes / (Completes + Disqualifies) = Incidence Rate%
- For example, you have a study with 5 completes and 5 disqualifies. Your Incidence Rate is: (5 / (5 + 5)) x 100 = 50%
- Incidence Rate is automatically calculated for Corporate, Essentials, Professional, International, and Premium plans, and can be found on the Monitor tab.
- A low Incidence Rate means that many participants were disqualified.
If you have a low Incidence Rate, ask yourself these questions:
Which question(s) disqualified participants?
Check the Results for the screener, and apply the All participants filter.
Is the screener qualifying logic correct?
- Verify your screener is set up correctly.
- Check for mistakes in the qualifying logic, especially for multiple-choice questions.
Is the screener too narrow?
- Make sure that the screener isn't too restrictive.
- If that’s the case, consider relaxing some of the criteria.
- Remember, when using more than 5 questions in your Screener Questionnaire, finding the right participants may be more difficult.
Do the screener questions make sense?
Have a colleague, ideally not from your team, take the screener to check if it's easy to understand.

- Learn about screeners in this UserZoom Academy course.
Conversion Rate (Drop off rate)
Conversion Rate is the number of people who completed the study divided by those who started it and is displayed as a percentage. (Completes / Completes + Disqualified + Drop Out)
- For example, you have a study with 5 completes, 5 disqualified, and 5 dropouts.
- Your Conversion Rate is: (5 / (5 + 5 + 5)) X 100 = 33%.
When Incidence Rate is greater than Conversion Rate, this means you have participants who dropped out of your study. This can be due to:
- Respondent fatigue
- Poor study design
- Other issues with the study
- If you're seeing a high number of drop offs, ask yourself these questions:
Do you have an effective Welcome page?
Refer to Customize your Welcome Page.
Are the tasks too hard?
- Find the tasks with the highest drop-off.
- Are they understandable and doable?
- Have a colleague, ideally not from your team, try them, and listen to their feedback.
Is the study too long?
- Check the average time taken to complete it.
Recommended study length:
- Desktop: 15 minutes
- Mobile: 10 minutes
- Try reducing the study duration or splitting it into more than one study.
Are you showing progress?
- If the study feels long, let participants know where they are in the study or how many questions remain.
- Add numbers on tasks (For example, 4/6).
- Add messages throughout the study (For example, "You're halfway through!").
Is personal information putting people off?
- Avoid asking for personal information or sensitive data (For example, bank account details). It could be illegal to do so under data privacy rules and regulations.
- Always review your study before launching it.
Asking open-ended questions on mobile?
- Studies with many open-ended questions can be harder to answer on mobile.
- It's recommended to change the study device to Desktop, or consider changing open ended questions to video questions.
Is it a Mobile Study?
- Mobile drop-off rates are naturally higher if there’s a video recording asking participants to download an app.
- The Advanced UX Research method is not recommended on mobile if there’s no video recording and no Navigation tasks. This study type requires participants to download an app.
- If the study does not have a Navigation task, use a Click Test, Tree Test, Survey, or Card Sort study.
Can participants take the study on a work computer?
- To account for participants taking your study on their work devices, set it up so participants don't need the UserZoom Surveys extension.
- Some companies don't allow users to install browser extensions.
Is it the timing?
- Responses may be lower and slower when people are at work, on weekends, or on/around holidays.
- Take into account the time difference in the country where you launch the study.
- If you launch a study in the US from Europe in the morning, people may be asleep, and you won't see participants until later in the day.
- If you launch the same study at night, people may be asleep, and you may not see participants until the next day.
- Do you have an effective Welcome page?
