Surveys on the Internet are becoming an indispensable reference for market studies thanks to the quantity and reach of the same, as well as the quickness, savings (in comparison with traditional methods) and efficiency that they entail.

Depending on the way that we carry out the data collection we can differentiate between two different types of surveys:

• Panel surveys: a sample group is selected and identified to be used in the survey and a follow up is carried out over  a period of  2 to 4 months, which provides high result dependability.
• Open surveys: the survey is positioned on different websites considered to be important for the kind of client we wish to poll; this is an anonymous survey. So as to guarantee results, control systems are placed in our sites and users may only vote once.
