I've got some "content sites" that are using wordpress that have around 15 different pages of content, but I made them all "pages" rather than "posts" because I think it looks better. That being said, is there a difference as far as SEO goes between using pages and using posts? Or is the only difference superficial -- how WP refers to them? I'm wondering because the pages and posts both have the same naming convention, www.domain.com/postname/ and www.domain.com/pagename/. Are there any other differences between them? Do search engines prefer "posts" because they're somehow different? I've noticed that WP auto-pings when you publish a new post, but not when you publish a new page. Does that matter? I can manually ping (I use MBP Ping Optimizer anyway which tells me exactly when things ping).
