WordPress Anatomy

1. WordPress Core. Main software files (php & javascript) & database (MySQL).

2. Theme. The look and feel of your site. You can buy a theme or have a custom one created for you.

3. Plugins. Add features and functionality beyond the core installation.

You need the WordPress core and a theme for WordPress to work. Plugins are not required.

How It Works Together

1. Content is added to your website / blog through the Administration Panel (part of the core).

2. It’s stored in a MySQL database.

3. Your website shows the stored database content. The appearance is controlled by the Theme.

How WordPress Works: Page Vs. Post


Contains static content that is not time-sensitive and will not change frequently like the Services and About pages.

An individual page can be the homepage.

Pages can be organized in a hierarchy. Pages (parent pages) and subpages (child pages) make it easier for visitors to navigate your site.


Contains timely content—educational articles, opinion pieces, news, or entertaining articles that collectively make up a blog.

An individual post cannot be the homepage.

Posts can be labeled and organized by categories and tags (keywords).

Post Example:

Post: Should I Use the Cloud for My Business?
Category: Use the Web
Tags: applications/services/ tools, How To, privacy/security

Posts appear in reverse chronological order on the main blog page and in the blog archives.


  Page Post
Goal Marketing Attracting attention
Content Tells a particular story about the business or gets a message out Getting to know the business, education, entertainment, etc.

How WordPress Works: Category Vs. Tag


Website taxonomies are made up of Categories and Tags that organize information. As a blogger, you use categories and tags to group posts together and make it easier for readers to locate related posts.

Category Tag
Focus Broad topics Narrow subjects
Equivalency Describes things that are equal in particular way/s Describe unequal things that need not be related at all
Hierarchal Yes No


A foodie blog consisting mainly of recipes could have categories like “Desserts,” “Breakfast,” “Entrees,” etc. Each recipe would fit into at least one category and also be tagged by ingredient or specific type of food—like cookie. If the blogger often refers to people who created the recipes, they could be tagged as well—then a reader could search for all Dad’s recipes at once.

Post Title: Dad’s Chocolate Chip Cookies
Category: Desserts
Tags: chocolate, cookie, Dad

Post Title: Banana Chocolate Chip Pancakes
Category: Breakfast
Tags: chocolate, banana, buttermilk, pancake
