Survey completion rate

Survey completion rate

Survey completion rate definition:

A survey completion rate is the amount of people who started the survey and that also completed it (clicked the 'Submit' button).

Tips for a higher completion rate:

- As with any conversation, you should start with an easy question
Surveys that opened with a simple, multiple-choice question had a higher completion rate on average compared to surveys that began with an open-ended question. So on average, you’ll lose about 6 people out of every 100 just because the opening question seemed too much work.

- Ask only what you need to know
It doesn't come as much of a surprise that longer surveys have lower completion rates. Why? Because the time needed to fill it out goes up. The chances of someone completing your survey is related to the number of questions. A 10 question survey has an 89% completion rate on average, 20 question surveys are slightly lower at 87%, followed by 30 question surveys at 85%.

- Don’t use many words when a few will do
When we constructed a model to discover the survey attributes that best predict completion rates, the number of words in the question text jumped out. We discovered that each additional word in the question text has a negative effect on completion rates.
