This commit moves the site to use the official Jekyll SEO Tag
plugin (https://github.com/jekyll/jekyll-seo-tag) to generate the
search-engine meta in the HEAD of each page. The title and canonical
URL output should be largely the same as before, but with additional
metadata, such as JSON-LD (for richer indexing), Twitter card
metadat, etc.
Like the other plugins, this should largely work out-of-the-box,
with no additional day-to-day configuration, but is customizable
where desired.
Remove baseurl from the config for three reasons:
1. It's not used anyplace within the site
2. The site’s base URL is only to be used when the resulting site
lives at a subpath of the domain. Otherwise, the subpath should be
nil, not /.
3. When the Pages Gem is loaded as part of the :jekyll_plugins
group, baseurl and url are set automatically.
Although the title already has a "name" entry, this commit replicates
the name as "title", and adds a "description" entry, both of which
are shared across common, official Jekyll plugins like jekyll-feed
and jekyll-sitemap.
This allows the feed and sitemap to properly output the title and
description in various places.
Jekyll Sitemap (https://github.com/jekyll/jekyll-sitemap) is an
official Jekyll plugin, which should serve as a drop-in replacement
for the existing sitemap.xml. The resulting sitemap should be largely
similar to the existing sitemap, but with a shared, battle-tested
template that accounts for all sorts of edge cases, handles collections
and static files, etc.
Jekyll Feed (https://github.com/jekyll/jekyll-feed) is an official
Jekyll plugin which should replicate the existing feed nearly
identically, but with a shared, battle-tested template that
accounts for all sorts of edge cases like relative links in feed
entries.
It should be a drop in replacement and "just work" without any
additional configuration.
