‘Pages and Posts in Feed’ is a simple plugin that modifies WordPress RSS feed to include both ‘Page’ and ‘Post’ types in the site’s feed. This creates a site feed with both pages and blog posts in it. Useful for those who use WordPress as a CMS.
The plugin needs no configuration. Just activate it, and you are good to go. Deactivating the plugin restores RSS feeds to their default state.

This plugin adds a “Unlisted?” checkbox in the “Publish” box while using the classic editor and Gutenberg. When this is checked the post will be excluded from most areas of your website by filtering pre_get_posts filter. This means posts will be excluded from RSS feeds, blog pages, widgets, category pages, archive pages, and more. Additionally it adds a noindex tag to the unlisted page to prevent Google from indexing the page. This is useful if you want to publish some information on your site and allows others to view it via the link without fully publishing.
