Sitemaps are used in the field of SEO for telling search engines what's available on a site. While there are extensions that generate sitemaps automatically, they are not that great (T1558). What I'd like to see is a script that automatically generates sitemaps for public wikis using generateSitemap.php. These wouldn't have to be updated that often, but maybe once a week/two weeks/month, depending on how long it takes.
If possible, it would be best to add the sitemaps to each wiki's respective robots.txt file, as:
I'm not sure what the process to do that would be, as it's currently a static file. Puppet templates? Do I need to write a PHP script to serve it? Without this, wikis would have to manually submit sitemaps with webmaster tools, which is less than awesome.
