Self hosting is cool, but if you actually want people to find your content my experience is that search engines will penalise heavily your ranking for being hosted off a residential IP that’s is not close to them and likely has a history of being unreliable. Unreliability and slowness both from the network latency and page rendering time (Wordpress doesn’t render so fast on a pi - at least when I tried it) will put you all the way to the bottom. If you don’t care about that then this is just fine, depending on what I am hosting changes where I put it, but stuff I want to be findable I host in cloud front/s3 as static pages and costs about $1 a month.
These are my notes on setting that up http://blog.cetinich.net/content/2020/2020-sphynx-ablog-blog...
