Site structure follows SEO tips from
https://johnnyreilly.com/how-we-fixed-my-seo

* The blog pages have as simple of an URL as possible. To this end, the home
  page of the site is actually the first index page of the blog.
* Customize the blog index page BlogListPage component to show the landing page
  as the first index page.
* Rename /archive to /blog to avoid a dated feel.
* Remove the date from post URLs using the slug property.
