Advertisers find it difficult to leave “walled gardens”, Google and Facebook, since they own “large pools” of first-party data. They remain dependant on these platforms because they provide incredible value in the form of number of users.
However, advertisers can’t independently asses Google and Facebook’s performance given their limited data-sharing with independent measurement and attribution firms to comply with GDPR.
