Say you've designed a small business website for a client - very simple, a few pages and a contact form.
Beyond the site functionality itself, what else should be included in a basic website package? What does every site need, regardless of how small or static it is?
How many SEO-friendly things should the site include without billing for SEO? Is just meta tags enough?
Does every site need a sitemap, even if it is only a few pages? How about if it is just a single page with the "sub-pages" being dynamically displayed in jQuery or CSS3 by parallax/scrolling etc?
What basic legal information is required? Does every site need a privacy page, even if the site has no user logins? Does it need copyright at the bottom? Any other legal info required to protect the client (or yourself)?
Are there any other best practices or additional information every site must (should) have?
