A great use for reddit is the ability to search posts and opinions about any niche topic. Will that be possible with Lemmy as it grows? Will I be able to Google “instant rice Lemmy” and get a comprehensive tier list of each brand?
I imagine search engines will have trouble with all the different instances(?). EDIT: Especially with instances that don’t have Lemmy in their name, I don’t think search engines would return them for Lemmy searches?
If Lemmy becomes a source of enough information like Reddit is, search engines will index it. SEO is a marketing thing, and a place like Lemmy doesn’t really need that. Google, DDG, etc. all put engineering effort into making sure sites with lots of information are indexed and available in their search results.
