Display last updated date in google meta tag

Hello @zyntsz,

Thank you for contacting Rank Math support.

Rank Math already adds the dateModified property in the Schema to inform the search engines of the last modification date. However, the date displayed in the SERPs is mostly taken from the one visible in the front end of the post. So you will have to make sure that the date displayed on your posts in the last modified date, not the published date.

Here’s a link for more information:

Hope that helps.
