A WordPress post can be thought of as a news or blog article. New posts are generally added on a regular basis and they can be put into categories or tagged with specific keywords. They are dynamic and usually keep your audience up-to-date with what you or your business are working on.
Pages are generally used in WordPress for content that doesn’t change on a regular basis. An example of a page would be ‘About Us’ or ‘Contact Us’. However, you will still be able to update the content on a page at any time.
