Whenever I want to find useful information on something i search the thing and add "reddit" to the end of my search. I would love to be able to do that with lemmy but currently it seems like nothing on lemmy gets picked up by google.
https://lemmy.ml sidebar shows "4.49K Communities; 129K Posts; 557K Comments"
Maybe only admin can discover accurate number of indexed pages by adding their site into a Google/Bing webmaster tools and verifying the site ownership.
