When determining the order of questions within the questionnaire, surveyors must be attentive to how questions early in a questionnaire may have unintended effects on how respondents answer subsequent questions. Researchers have demonstrated that the order in which questions are asked can influence how people respond; earlier questions – in particular those directly preceding other questions – can provide context for the questions that follow (these effects are called “order effects”).
First, thank you for providing this extensive list. I wanted to offer a quick follow up. After reading your post I decided to give Survey Junkie a try and I’ve already closed the account. Yes, I can tell it’s well organized and it is definitely a user-friendly platform. The problems I experienced were first that not one of the surveys they emailed me about were available. I did, however, complete several surveys from the site itself and I found them to be lengthy – in itself, not a problem but 3 out of 5 told me I didn’t qualify after I’d already invested 10 – 12 minutes filling out the forms. They got more than enough information from me to be useful which is an old and highly unethical trick in market research – which happens to be my background. All in all a LOT of wasted time.
Sometimes survey invitation links direct you to other survey companies, rather than keeping things in-house, which can feel a bit like spam. As is common in the industry, you can sometimes get stuck filling out lengthy qualifying questions which take up to 30 minutes just to see if you’re eligible for a survey. Needless to say if you find out you are not then this is extremely frustrating.

Lastly, because slight modifications in question wording can affect responses, identical question wording should be used when the intention is to compare results to those from earlier surveys (see measuring change over time for more information). Similarly, because question wording and responses can vary based on the mode used to survey respondents, researchers should carefully evaluate the likely effects on trend measurements if a different survey mode will be used to assess change in opinion over time (see collecting survey data for more information).
For employees who can’t afford to be distracted a number of times a day, having a controlled environment can be key to their productivity. Working from home can allow workers to minimize distractions and increase the time they spend focused on a project. It stands to reason that, in the end, companies benefit from these remote employees by getting projects completed faster with fewer mistakes. 

Companies, brands, and organizations from around the globe are constantly seeking the opinions of people just like you to help shape the products they develop and how they market them. They count on paid online surveys to provide them with reliable information. If you spend time online and enjoy giving your opinion, paid surveys are a great way to earn a little extra cash while helping these companies.
