By default, WordPress comes with two default content types. They are called posts and pages.
Posts are part of a blog and are displayed in reverse chronological order. Pages are static and not part of a blog.
See our guide on the difference between posts and pages.
To add a new blog post, head over to the Posts » Add New page.
To create a new page, you need to visit Pages » Add New page.
Both page and post-edit screens look similar, with minor differences.
For detailed instructions, see our guide on how to add a new blog post in WordPress while utilizing all the features.
