We are using an external tool called Siteimprove, who are using sitemaps to crawl the webpage for spelling errors and etc.Recently we have released a self-service environment, where there are pages behind account authorization, that we wish to crawl. In order to do that, we have to add them to a sitemap. Using Geta Seo Sitemaps (version 4.0.0), has anyone any experience with adding pages behind a login to a sitemap, which aren't public for search engines?
If you can override this (https://github.com/Geta/SEO.Sitemaps/blob/eebf3007c5004a7351ca5ce59eb6de95c9ff0252/src/Geta.SEO.Sitemaps/Utils/ContentFilter.cs#L18) implementation, then you can control filter yourself and decide whether you want to include or exclude protected pages.
Even if you add the URLs to sitemap.xml, how are Google supposed to crawl the pages if they are behind account authorization?
