One of the biggest sources of confusion to new WordPress bloggers is the difference between Posts and Pages. They look similar on the front end, their Editor page looks the same on the back end, they both start with a “P” – what’s the difference?
In six words, Pages are static, Posts are social.
Pages are like old-time HTML sites used to be. They sit there and they tell you stuff. The most prevalent Pages are About, Contact, and Home. Pages only change when they are updated and they stay that way until the next time. They have no dates, no categories, and no tags. Pages are, in a way, self categorizing.
