Lead generation using incentivization is generally regarded as the lowest quality form of lead generation. Visitors to third party websites are offered "points" or cash or entry into competitions in exchange for giving their data to the third party.
Being rewarded for filling out forms can lead to unscrupulous individuals signing up multiple times. Used correctly however, it can also result in a large volume of rapidly-generated leads who are now aware of your product or services.
From a GDPR stand point, incentivising people to sign up to receive information from your brand has to be treated very carefully. Whilst it is not completely outlawed, incentivisation must not be compulsory or the data gathered will be non-compliant under the GDPR regulations. If you are planning an incentivised campaign then it is essential to get appropriate expert advice.
