"building gui with ruby" - second search result in google for me. It's a lot more than just the name that goes into being discoverable and related to a topic/keywords/etc.
OK, but what if I don't want the main site, but other resources like examples and user troubleshooting of obscure issues?
The Shoes 3 blog’s last post was a year ago, the Shoes 4 blog was last updated in 2017.
I don't think SEO is the main thing Shoes needs for viability.
