How to remove post publishing and updating date structured data in the Hueman theme
Published and updated dates are used by Google structured data markup.
They are enabled by default in the Hueman free and pro themes. Those information are not visible but they are printed in the page to help the Google bots do their jobs.
If you want to remove them, you can go to Appearance -> Customize -> Advanced options -> Performances and SEO
Find the setting -> Use Structured Data Markup for your posts
Uncheck this option and save changes.
