Common Mistakes in Online Surveys

A good online survey is more than a good questionnaire. Whether it delivers usable results in the end also depends on how you run it: a clear objective, a sensible duration, the right way to reach your participants and a sound approach to data protection and anonymity.

These mistakes often weigh more heavily than a poorly worded question. They usually surface only once the survey is live or already finished, and by then they can no longer be fixed. A technically sound questionnaire is of little use if the objective is unclear, the survey runs too long, or participants do not trust how their data is handled.

This page is about the mistakes around running the survey. How to build the questionnaire itself, wording your questions, choosing and designing answer options, is covered under The most common mistakes when creating questionnaires.

These are the most common mistakes when running online surveys, and how to avoid them:

Common mistakes at a glance

No clear survey goal

Without a clearly defined goal, a survey ends up delivering data you can't act on.

Surveys that are too long

Overlong surveys overwhelm respondents and lower data quality.

Missing answer options

When respondents cannot find a fitting option, they answer wrongly or not at all.

Imprecise answer options

Overlapping or incomplete categories make a clear choice impossible.

Privacy and anonymity

People unsure what happens to their answers respond dishonestly or drop out.

Accessibility ignored

Inaccessible surveys exclude respondents and distort the results.
