Pages:
Pages are for static information. There are no categories or tags or publish dates on pages, but rather they are used for evergreen content. Examples of pages would be Contact Us, About, Privacy Policy, FAQ, etc. These pages usually do not have any kinds of social sharing links and, by default, comments are disabled.
Posts:
On the other hand, posts are used for adding content regularly. They are stored in the archive in reverse chronological order, meaning that the newer posts will be the first thing viewers see. Posts can be assigned categories and tags to make it easier to filter and search by topic. Posts are ideal for inviting social sharing and comments to encourage community engagement.
Categories:
Categories are like the names on file folders or like the headings in a table of contents. These are how you can organize your posts and make it easy for readers to look for information. You also have the option of creating sub-categories. By default, posts are assigned the “Uncategorized” category. I recommend renaming this to something like “Other” or “Miscellaneous” to give it a more intentional look if it gets left on a post. You can rename this category by going to Posts>Categories>Click ‘edit’ under Uncategorized>Rename the category. Categories are also used when setting up different sections on some page designs, like “Featured” and “Portfolio” because you can use Posts blocks and then filter by the category or subcategory.
Tags:
Tags are for adding more descriptive details to your posts. This helps the search feature on the website and site indexing know the key features of the post. You can add as many tags as you want to each post.
