One of the best things about reddit was looking for answers or other users with the same problem as you, and since Google didn’t really help with that anymore and instead insisted on giving you business results, the best practice was to put your search terms in followed by ‘reddit’ and you’d find your answer.
I guess you would need the name of the instance where the community resides. But usually if you search about specific questions the site with the information will appear (be it reddit or some lemmy instances) without adding it to the search term
The issue is google for the last few years has been prioritising businesses and services with really good SEO. And ads.
So in order to find helpful user content I always had to add Reddit to the search query.
