eesy_MMDate – Manage modified date on website or blog

It updates the “last modified” date of your blog posts or pages on a schedule, so they appear fresh to search engines – without altering the actual content.

Google and other search engines take the modified date into account when determining the freshness and relevance of content. Regularly updated posts are more likely to rank higher.

No, only the meta information (the modified date) is updated. Your original content remains untouched. ---### Technical Questions

A WordPress cron created by the plugin makes hourly checks to see if the selected posts were already updated today. If not, it looks if the specified time is reached. And if that condition is met, it updates the post_modified of all the posts. The new date that will be given each day is calculated from the "Days to Add" field (new post_modified = value + current post_modified). A value of 0 sets it automatically to the current date.
