What are your thoughts in making content in this instance more visible in search engines via IndexNow? On a technical level, how feasible is this?

The fediverse is weird with our content duplication. Which is normally harmful for SEO. But I've been out of the SEO business for a while so it's possible now that search engines end up handling this.

This was why originally on all the subdomains we have a dedicated robots txt -
https://reddthat.com/robots.txt vs https://old.reddthat.com/robots.txt
To ensure that we don't have duplicate content across our subdomains which would hurt SEO (or what normally happens, is "old" would become the default or rank higher due to it being more text heavy and less JS heavy so it loads faster.

But LW and other more "popular" instances could very well end up being the default as they might have more Authority.

Now what about your request, this looks like bing and yandex ? Does it work for Google?

Currently we'd need to build something, maybe like LemmyWebhook and then write some logic so that only when a new post that is on a local community & not NSFW, do we send the request.

But considering our low post count, we could probably get away with a daily cron task which gets the list and sends it as a batch. Which would be less of a change and easier.

But, I guess the question is should we?
Are we lacking in SEO? Do our posts take too long to show up?
