@simon suggested to use a Sitemap plugin, so search engine users who look for their problems can easier find forum topics with solutions.
I’m not sure whether we need a plugin like that for better indexing, as we never migrated the forum to a different URL or so. There is some discussion here for reference: https://meta.discourse.org/t/discourse-sitemap-plugin/40348
But installing it probably doesn’t cause much harm, so I would still go for it. Other opinions?
