Respond To Paid Surveys

As the name suggests, this technique involves responding to online surveys or satisfaction surveys. You are then paid several euros by the brands that ordered the panel.

Of course, if your real objective is how to get rich, sorry it will not happen by answering paid surveys, but it's an easy way to supplement your income. You can expect to receive ten euros per site and per month.

There are plenty of paid survey sites, including:
Toluna. An attractive interface and funny polls. Payments can be made by transfer or gift certificate.
GreenPanthera which gives a welcome bonus of 4 € and offers really well paid surveys. Only downside, its interface is a bit ugly.
Isay : A very reliable polling site, and pleasant to use.
