There are two main types of content on your WordPress website, posts, and pages.
What are posts?
Posts are blog posts, they often display their publish date, author, feature image, and can have comments. They are often displayed in an “archive” (like on a blog) where the newest post is at the top of the list, and the oldest is at the bottom.
Posts can also have categories and tags, which allow your readers to see an “archive” of all posts within a certain category or tag.
Posts are edited with the default WordPress Editor whereas pages have the additional option of using the Page Builder.
What are pages?
Pages are what form the website’s structure. Standard pages are home, about, and contact pages – but you can make a page for anything you need. Pages are also used for “endpoints” such as “Subscription Confirmed”. Pages can also be used for things like registration forms, carts, checkout, and account details.
Pages have the option of being edited with the Page Builder, which gives additional options for layouts.
It’s also worth mentioning the difference between post layouts and page layouts.
Post Layouts
The posts on your website usually share the same layout. The content for each post is not managed by the page builder, it’s managed instead in the Posts section of your website. Posts are usually written like articles, updates, announcements, etc…
Page Layouts
Since pages usually exist for their own unique reasons (about, sales, confirmation, registration, etc…), we use the Page Builder to build custom layouts for each page. Of course, some pages will share the same simple layout, but main pages like your home page usually have a completely unique design to meet their goal of welcoming your readers.
Your website menu is made up of pages, whereas your blog is made up of posts.
