Understanding the Difference between Posts and Pages

In this post, we go into great detail about how WordPress archives
your published content on your site by filing it under categories and tags, as
well as by date (year/month/day/time of day), and through the use of pages,
rather than posts.

Pages, in WordPress, are different from posts because they don’t get
archived the way your blog posts/articles do: They aren’t categorized or
tagged, don’t appear in your listing of recent blog posts or date archives,
and aren’t syndicated in the RSS feeds available on your site — because con-
tent within pages generally doesn’t change. Pages are considered static or
stand-alone content and exist separately from the archived post content on
your site.
