This is THE distinction to grasp right at the start.
Posts
Content that is dated and chronological: blog entries, news items, announcements. They are filed under categories and tags, and appear from the most recent to the oldest.
Pages
Content that is fixed and timeless: « Home », « About », « Contact ». They carry no date and form the permanent structure of the site.
| Post | Page | |
|---|---|---|
| Nature | Dated, blog | Fixed, structural |
| Categories | Yes | No |
| Example | « Our 5 tips for… » | « Contact » |
Simple rule: if it is dated (a news item), it is a post. If it is permanent, it is a page.
