If I has a Website where I collects the user data on Sign Up Can I use the profile data for ad?

Yes, You can use those users’ profile data to target the profile based ads in his Website. When the User is logged in, the publisher can send those details through an invocation tag and the Adserver will provide the appropriate ads targeting their profile. So the first party data plays a pivotal role in the targeting.
