Our plugin settings allow to disable Image, Video, HTML Sitemaps, but currently it’s not possible to disable main XML Sitemap. So we can recommend you to change XML Sitemap URL to not indexing URL, for example secondary-sitemap.xml and disable options:
- Add Sitemap Output URLs to site “robots.txt” file
- Automatically ping Google, Yahoo, Ask, Bing every day
Then XML Sitemap should be available only with direct link. In this case, it will not affect to your website indexing.
Also, we will work new feature Disable XML Sitemap, and try to release with coming updates. So you can easily disable XML Sitemap in Settings with the following updates.
