Comment on Can Lemmy instances make content of their sub-Lemmys indexable by search engines?

Duplicate content shouldn’t be a problem as every post has a source URL. This is linked in the HTML head as the canonical URL. That way search engines know where something is from and that only that one is the true source.

Except lots of people post the exact same thing to every community with a related name across many instances.

I mean, do they? Do the search engines do that? I don’t know that they do. They could, but why spend the time making that?

  That’s standard HTML stuff available for decades.

    Semantic html is largely ignored by search engines. If you’re talking about the tag, it does not syndicate, at least on Google.
    
    If you’re talking about iframes, Lemmy does not use them. The content appears as though your home instance hosts it (hence why images need to be moderated off-instance so badly).

    Google supports rel canonical link annotations as described in RFC 6596.
