Second-party data includes all first-party data that, however, is not collected directly by the company but by trusted partners of the company.
As is the case with first-party data, second-party data can also be collected through specific software or technological solutions that, however, the company, does not own privately and for which, therefore, it forms collaborative relationships with trusted partners.
The extent to which second-party data complements first-party data, depends, of course, on the type of collaboration that is created: broadly speaking, however, we can say, how the ultimate goal remains firm, which is to create more complete user profiles especially with regard to qualitative data on behaviour and interests.
Second-party data are usually labeled as collaborative data precisely because they often complement first-party data and are very important because, often, they are difficult to obtain from the company itself.
Second-part data are acquired through real economic transactions: they are usually particularly secure because the company that needs to acquire them goes directly to the organisation that has them and they are, in most cases, accurate and quality data. Second-party data, in fact, is said to be another organisation’s first-party data.
