I'm in the process of building a landing page that will be used for Google ads, but need advice from experienced users on how to properly set it up. I know the content I want to put on there, and the design, but don't know about the following:

1) Do I set it up in the following format: https://website.com/landing/landing-page-title? If so, should I use /landing/ or simpler and a less obvious name instead of "/landing/"?

2) Should I exclude this page from getting indexed by sites? What if it's not a limited time offer, but an ad for a service from the company?

3) Do I include the regular site's header/nav at the top, or simply have the logo & a CTA button to reduce the amount of distractions and confusion?

4) What about footer? Keep it minimal, related to the service being advertised, or original site's footer? Also, if it's a limited footer, do I include the TOS/Privacy/Cookies/etc. legal pages there?
