Online panels represent an important resource for market research. Today, many marketing decisions are based on data that is collected via panels with consumers that fill-out questionnaires online. Consequently, there is a large market of companies providing online panels for research. We see online panels of various kinds: large, random-access consumer panels with over 5 milion members, small specialist panels with members belonging to a professional group (doctors, IT consultants etc.), panels recruited via in-depth interviews, panels recruited via the internet, panels that pay respondents money for participation, etc.

NOPVO - industry-wide study to investigate panel effects


Increasingly, buyers of market research ask the question about panel effects. To what extend have the different panel strategies an effect on the data that is collected and who are the respondents that participate in such panels? For this reason, an industry-wide study has been conducted to investigate how choices of panel providers influence the outcomes of research in which online panels are used.

Goal of NOPVO

  • Provide insights into the differences of online panels
  • Create transparancty in the market of online panels
  • Recommend opportunities to improve the quality of online panels
  • Allow owners of online panels to better understand how their strategy effects the outcomes of research
  • Drive the future development of online panels
The NOPVO study has been conducted in the Netherlands. In this country, there is a large market for online panel research. The majority of all opinion and market research data is resourced by online panels.

Results of NOPVO

NOPVO is a unique study. With 19 participating panels that capture 95% of respondents to online marketing research in the Netherlands, it presents an excellent overview over the different panel management practices in the market. In addition, the empirical study provides rich information on a wide variety of topics (e.g. work and life situation, politics, religion, brand awareness, ad awareness, and why they participate in online surveys). By linking this information to the general panel overview, knowledge can be gained on the relationship between (1) panel recruitment, panel monitoring, and panel maintenance on the one hand and (2) response rate, participation rate, response time, representativeness, quality of answers, response motives, and Internet usage patterns on the other hand.
