When writing a blog post, you are essentially creating a page. When you write a page, you are creating a static document that is viewable on the web.
A blog post, on the other hand, is a dynamic document that can be viewed and edited by the blogger immediately. A blog post can also be published as a page after it has been edited, but this is not always the case.
One of the main differences between page and post is that posts can be updated and amended at any time, while pages are static and cannot be updated. This makes posts much more versatile and easier to use than pages, as they can be used to create a permanent record of your work or to provide supplementary information on an existing topic.
Another major difference between page and post is that pages are typically associated with individual blog posts, while posts can also exist as standalone documents. This means that you can publish a new post without publishing any old pages first – this is useful if you want to keep your readers updated on new developments without having to update all of your old content too.
Overall, then, page and post are two very different types of document that have different purposes and advantages. Page is generally used for static documents that can be viewed by anyone on the web, while post is more suited for dynamic documents that can be updated by the author immediately.
