This plugin alters this behavior and prevent the WordPress HTML editor from removing the schema.org/microdata markup. ### Credits @azaozz suggested the solution. See the issue discussion here: https://core.trac. wordpress.org/ticket/27931 ## Installation Just install the plugin as usually and activate it. Once activated, it will keep your markup from being removed by the HTML editor. No setup required. ## Reviews ![](https://secure.gravatar.com/avatar/41501a831190ffdb6517c0e4987b75643aec4717d28e9dbfb643a8fec7933350? s=60&d=retro&r=g) ### 󠀁[heading tags](https://wordpress.org/support/topic/heading-tags-3/)󠁿 [alikargozar](https://profiles.wordpress.org/alikargozar/) February 15, 2023 Please protect the attributes that are in the heading tags. ![](https://secure.gravatar.com/avatar/ec4487736be71cce2a1c2236f29de4e54cc6ad6eff08d5fd7784664f18dca1e0? s=60&d=retro&r=g) ### 󠀁[Great plugin](https://wordpress.org/support/topic/great-plugin-33583/)󠁿 [juelu](https://profiles.wordpress.org/juelu/) March 2, 2022 1 reply Works like a charm for protecting our markup! ![](https://secure.gravatar.com/avatar/68130d30cb8a93a16226bdaeb588d31d92592431cdd0161f4022c4a2e73523ab? s=60&d=retro&r=g) ### 󠀁[Simple yet Powerful](https://wordpress.org/support/topic/simple-yet-powerful-14/)󠁿 [axxixx](https://profiles.wordpress.org/axxixx/) October 6, 2016 1 reply This is a really good plugin.
