https://fa.wikinews.org/sitemap.xml, or other URL defined at https://fa.wikinews.org/robots.txt, should contain a sitemap udpated regularly with generateSitemap.php. Any reason not to?
Context:
I've been writing articles for fawikinews, I realized my articles are not being indexed by google, latest article was indexed was for about a month ago, also we use GoogleNewsSitemap extension to generate news xml sitemaps using [[Special:NewsFeed]] so I added sitemap line to MediaWiki:Robots.txt but nothing happened, I also realized www.wikinews.org is redirecting to en.wikinews.org so I checked MediaWiki:Robots.txt on English wikinews, I saw people were adding sitemap links for frwikinews and eswikinews, so I asked an sysop to add a sitemap line for fawikinews, and right after that night I saw my articles are being shown in the first page of Google SERP.
I also read someone in mznwiki is telling some pages with the age of at least half year are not being indexed by google.
My question is do we use generateSitemap.php? where are the generated files located at? can we use wgSitemapNamespaces and wgSitemapNamespacesPriorities for them?
