Your starting prompt.
Compare landing page conversion rates during [period] by device, channel and new-versus-returning visitor where available.

Separate periods before and after documented releases and preserve segment mix. Prepare an investigation table without attributing a conversion difference to design changes unless a valid experiment supports that conclusion.
