I am creating my first website for a small chiropractic practice, I have an informational/link page with an iframe in the center and 2 menus, when someone clicks a link it displays the ENTIRE site at the page requested inside my iframe, the site is fully interactive, and is not cut off in any way, it shows their logos, menus, links, sponsors, ads... Is this ok to do?
