I've created several small scale websites, usually for small businesses. They usually contain some information about the company, a contact form, and sometimes a few dynamic parts : news, pictures, etc.
I could generate XML sitemaps for these websites, but I am not sure what would be the point ? For websites such as these ones, where the pages are limited and easily discoverable, is it useful to generate a sitemap ? Is there a clear advantage to do so (in terms of SEO mostly) ?
