In recent years, as more and more people have internet access and use the internet regularly, conducting surveys online has become an increasingly used and credible alternative to classical approaches, such as face-to-face or telephone surveys. Of course, internet penetration varies widely – even within Europe – but an online approach can often be the best balance between cost and quality.
TNS opinion offers the largest online sample with the broadest geographical coverage in the world. Online can be effectively used for all kinds of surveys – from standard quantitative questionnaires, to more complex behavioural experiments. It is increasingly used for qualitative studies and at TNS opinion we are pioneering the tools and platforms for conducting online groups, depth interviews, and ethnographical studies (e.g. blogs, video diaries).
