This is one of the hardest parts of our job..."Oh, your son built the site"
I hate hurting people feelings about their baby/website. I think there are example we should take a after who have spent tons of money researching and developing their site i.e.: Apple, Nike, Amazon, Go Pro, Shumway Van and I could list many many more. I think that we should ask ourselves "why are they building their site to look and feel that way?" Simple, clean and easy to know what your buying or learning about. We don't want to increase your visits and not increase your sales. Websites are not just a business card anymore.
Every website has to be built with search engine optimization in mind. Learn more on why your sons find in high school should not built your site.
