Sharing Collectives Publicly Using a Simple URL (i.e. Improving SEO)

I’ve started using Collectives to store my cheat sheets and it’s working very well for my needs! Here’s a public-facing URL:

It’s a very low-friction way of managing content, and I love that I can share the results so easily.

What I would like to eventually do with it is share it using a URL like this:

I would also like to make that public version of the site easily “crawlable” by Google and other search engines. Right now I don’t think that it is, but I’m not an expert on such things.

So I guess my question is, is anyone out there using Collectives like this? If not, then does anyone know of a non-terrible way of making this work? For a little background, I host my own Nextcloud server. I know a little bit about web server configuration but I don’t know a ton about URL re-writing.
