I want to display the date in the search results and take SEO measures.
If the target page does not include a date such as the release date (update date)
How should I put the time tag?
Wouldn't it be nice to have an empty time tag somewhere with a datetime attribute?

If the other method seems to be good, I would be grateful if you could let me know.

    Empty tags can be ignored and should be avoided.
    If you don't want to display it on the page, you can hide it with CSS or style attribute (display: none;).
    Originally, I think that the date of the posted article should be displayed on the page as well.
