We carry out CAWI surveys, from the computerization of the questionnaires to the data collection (responses) with the help of our panels of consumers in Italy and Worldwide.

Questionnaire computerization

We offer a script service to create web-based questionnaires with extensive customization on the LimeSurvey platform.

We will computerize your questionnaire according to your preferences and customizations and we will propose methodological suggestions to improve the performance.

We make the questionnaires that informatize device friendly, optimized to be compiled on each device.

In order to guarantee a high quality in data collection through a web questionnaire (CAWI), our statistical technicians provide the service for preparing web questionnaires (scripting) following the state of the art.

Collection of questionnaires

One of the crucial and most difficult stages in conducting surveys is the compilation of the questions.

We offer our assistance for data collection (answers to the questionnaire) for your CAWI projects: from the representative selection of the respondents, to the sending of the invitations to the questionnaire, to the actual collection of the questionnaires on our panels.

We select for you and we offer representative statistical high-quality samples (mostly recruited offline, through CATI interviews) for your surveys, research and surveys of various kinds in Italy and Worldwide.

At the end of the data collection we perform weighting and basic processing (based on your request) of the data collected before delivering them to you.

Panel Online Italy

We have a reliable and secure consumer panel on the national territory, without false identities (as it is mainly collected offline), which we will put at your disposal to help you gather the necessary answers for your questionnaires in a very short time.

Panel Online Worldwide

For your international projects, in addition to the service of computerization of the questionnaires we put at your disposal our international panels for a dynamic and efficient collection of answers for your questionnaires.
