I'll also provide insights into how this site was made, as well as code examples and thoughts on how those could be further developed.

Improve Response Times on Your NGINX Web Server with HTTP/2, Compression and Cache Headers
NGINX is a lightweight and fast web server that meets the content delivery needs of most small to medium sites. Loading speed is now a crucial metric in how the search engines rank websites. With a little basic configuration you can vastly improve the performance of your server and reduce delivery times. Here, I give an introduction to enabling HTTP2, gzip compression and cache headers.
Wagtail - Configure the robots.txt and Block Search Indexing (the correct way)
Rather than just being a static file, you can use Django/Wagtail templating to create a dynamically generated robots.txt. This is not the place to block search engine crawlers though, I'll show a method to apply that from your base template.
Configuring a Dynamic Sitemap on Wagtail
A sitemap lists a website’s most important pages, making sure search engines can find and crawl them. It's important to keep your sitemap up to date for optimal SEO. With a quick bit of coding, you can set your sitemap to be created dynamically on demand, ensuring it always reflects the latest content. There's another tweak needed for routable pages and multi-lingual sites using wagtail-localize.
Making Wagtail pages more SEO friendly with Wagtail Metadata
Wagtail pages are great for creating a lot of rich content straight out of the box, but for SEO optimization, they need some tweaking.
Here, I subclass the Page model with some help from the wagtail-metadata plug-in.
This subclassed model becomes the base for all site pages and holds all the data for og metadata, twitter cards, page description etc..
