I’ve been playing with googles search indexing and my personal instance. My instance is a subdomain named lemmy of my vanity URL I’ve kept for years. One thing I’ve noticed is that even though I run an instance with one user and one community, my personal website under the domain - which is static and lame - has risen from 50th to 23rd with certain search terms.
My point relative to the original question is that lemmy seems to be inherently interesting to googles crawlers and spiders and wtevs.
