By default, the XML Sitemap in All in One SEO will include all content which you've chosen to show in search results.
However, you may want to choose which content you submit to search engines.
If that's the case, All in One SEO can help you.
To get started, go to Sitemaps in the All in One SEO menu.
In the Sitemap Settings section you'll see settings for Post Types and Taxonomies. By default, these are set to include all post types and taxonomies.
If you want to change which content is included in your XML Sitemap, uncheck the Include All checkbox and you'll see a list of all the post types and taxonomies for your site.
Now you can uncheck the box for any content you don't want to include in your XML Sitemap.
IMPORTANT:
Any content that has been set to be excluded from search results or set to Noindex under Search Appearance will not appear in these settings.
NOTE:
Search engines can still index your content and display it in search results even if it's not included in your sitemap.
Including content in your sitemap just means it’ll be added, updated and deleted on search engines much faster than waiting until they find your content on your own.
