I know with posts that they show the date of the post and so on, under the meta description in Google. However, with pages you never see the date the page was published in the meta description. Somehow, Google is reading these pages as posts. Is there a way to correct this or a possible update?
Not quite sure I understand what you want to do, but when you say Meta Description, this is the meta tagging websites have in the source code. For pages in my themes, I did not put meta info such as published date, author, etc., in the pages, but only for blog posts.
