Or any online survey for that matter.

SurveyMonkey has published a great document on "Smart Survey Design" which is a collection of guidance from many sources.

E.g. a good checklist of concerns regarding the survey and question design that, as the survey designer, you should consider:

• Do the respondents feel comfortable answering the questions?
• Is the wording of the survey clear?
• Is the time reference clear to the respondents?
• Are the answer choices compatible with the respondents experience in the matter?
• Do any of the items require the respondent to think too long or hard before responding? Which ones?
• Which items produce irritation, embarrassment, or confusion?
• Do any of the questions generate response bias? Which ones?
• Do the answers collected reflect what you want in regards to the purpose of the survey?
• Is there enough diversity in the answers received?
• Is the survey too long?
• According to your test audience, have any other important issues been overlooked?
