In contrast, pages are for non-hierarchical content: pages like "About" or "Contact" would be common examples. Pages live outside of the normal blog chronology, and are often used to present timeless information about yourself or your site -- information that is always relevant. You can use Pages to organize and manage the structure of your website content.
In addition to the common "About" and "Contact" pages, other examples include "Copyright", "Disclosure", "Legal Information", "Reprint Permissions", "Company Information" or "Accessibility Statement".
In general, pages are very similar to posts in that they both have titles and content. WordPress Theme template files maintain a consistent look throughout your site. Pages, though, have several key distinctions that make them different from posts.
Just as you can have subcategories within your Categories, you can also have subpages within your Pages, creating a hierarchy of pages.
For example, a WordPress site for a travel agent may feature an individual Page for each continent and country to which the agency can make travel arrangements. Under the Page titled "Africa" would be subpages for Cameroon, Lesotho, Swaziland and Togo. Another parent Page "South America" would feature subpages of Argentina, Brazil and Chile.
The structure of the pages on the site would then look like this.
In the above example, the Permalink for the Cameroon Page would be:
To change the URL part (also referred to as "slug") containing the name of your Page, use the "Edit" (or "Change Permalinks" in older WordPress versions) button under the Page title on the Edit screen of the particular Page, accessible from Pages tab of WordPress Administration Screen.
WordPress is able to automatically generate a list of Pages on your site within the sidebar or footer, for example, using a Template Tag called wp_list_pages(). See the wp_list_pages page for information on how to customize how WordPress displays the list of Pages on your site.
There are also WordPress Plugins that will help you display a list of Pages within in Posts and in other areas of your WordPress Theme.
Individual Pages can be set to use a specific custom Page Template (a WordPress Theme PHP template file, e.g., my-custom-page.php) you create within your Theme. See Custom Page Templates for instructions on how to create a custom template file for a Page. This new Page Template will then override the default page.php Page Template included with your Theme.
A web page can be static or dynamic. Static pages, such as a regular HTML page that you might create with Dreamweaver, are those which have been created once and do not have to be regenerated every time a person visits the page. In contrast, dynamic pages, such as those you create with WordPress, do need to be regenerated every time they are viewed; code for what to generate on the page has been specified by the author, but not the actual page itself. These use extensive PHP code which is evaluated each time the page is visited, and the content is thus generated upon each new visit.
Almost everything in WordPress is generated dynamically, including Pages. Everything published in WordPress (Posts, Pages, Comments, Blogrolls, Categories, etc...) is stored in the MySQL database. When the site is accessed, the database information is used by your WordPress Templates from your current Theme to generate the web page being requested.
An example of a static page might be an HTML document (without any PHP code). The problem with purely static pages is that they are difficult to maintain. Changes you make to your WordPress settings, Themes and Templates will not be propagated to pages coded only in HTML. The Page feature of WordPress was developed to alleviate this problem. By using Pages, you no longer have to update your static pages every time you change the style of your site. If written properly, your dynamic Pages will update along with the rest of your blog.
Despite the dynamic nature of Pages, many people refer to them as being static. They are actually called "pseudo-static" web pages. In other words, a Page contains static information but is generated dynamically. Thus, either "static," "dynamic," or "pseudo-static" may be validly used to describe the nature of the WordPress Page feature.
