What’s in a Page ?
– Pages are where you put your evergreen or pillar content — timeless information. Your About page is a Page, not a post, because it’s not going to change much over time.
That’s not to say you’ll never go back and edit or make changes on a page. Of course you can, and you will. But changes will be infrequent.
Pages are hierarchical. That means you can arrange sub-pages under pages. Google likes structure and hierarchy, so creating pages and sub-pages will please the search engine gods as well.
What’s in a Post ?
– Unlike pages, posts are designed to encourage social interaction and sharing. You don’t care if readers share your About page, but you definitely want them to share your article on the latest whiz-bang development in your industry.
You can’t create a hierarchy with posts, but you can make them searchable using tags and categories.
Posts go into a blog feed. If you have a blog on your site, the most recent post is at the top. Pages don’t go there. If you set up an RSS feed so your readers get an email when you add something new to your site, they only get emails for posts, not pages.
