white label is a copy of main cam site hosted by cam program using your domain with your logo, don't expect direct google traffic there.
example:
main site:
https://stripchat.com
white label:
https://omg.adult
white label actually is your site, but still not enough to bring money on it's own, you need to find a way to send traffic to it, either from network of blogs or buying google ads, or some other creative way using cam program's promo tools...
