Page versus post, although they may often hold the same information, there is one key difference that sets them apart: purpose.
Pages tend to hold information that is more permanent. They usually contain information that does not change. This could be an about page, contacts, or details about the company. Although the content might not change, it is still important to keep the website fresh so as to not lose viewers. Pages fill the need for essential information the users can always return to.
Posts, on the other hand, are timely. They’re used for content that’s tied to a specific moment, update, or idea. For example, what you are doing in the coming week, what you are thinking about, or recent news/events. Posts can be categorized by tags, making them easy to search through. Posts capture the “right now”.
