Posts
Posts are made to blog or share other current content such as announcements, events, or latest news. The post feature is designed to support regular, frequent publishing of new content and share it widely. Unlike pages, posts are designed for social sharing, commenting, and search engine optimisation, and they can be syndicated via an RSS feed to notify readers of new updates.


All Posts
As simple as it sounds, it’s all your posts in one place. Where you can categorise them, see who posted it, when it was published, and even the SEO status for it.
Add New
You can either use this or the button in the top left corner of the “All Posts” page to create a new post.
Categories
This subpage allows you to create and manage new and existing categories. To make your post easier to find for both you and your visitors, use categories. They are intended for broad grouping of your posts. Think of them as general topics or the table of contents for your WordPress site. Categories are hierarchical, which means you can create subcategories. WordPress allows you to add a post to multiple categories. This can be multiple parent categories, or a parent category plus a subcategory or subcategories.

Tags
WordPress tags are one of the tools you can use to group your posts based on similar details. They are intended to describe specific details about your posts. The purpose of tags is to help link related posts together. Think of them as a register section in a book. Each tag is like a keyword in the index. They let you micro-categorise your content. Tags are not hierarchical.
One of the biggest differences between tags and categories is that all WordPress posts must be archived under a category (if you don’t give a post a category, it will be archived under “uncategorised”), but they do not need to have tags.
