For years I've been doing old-school html and php pages, but just recently started getting used to setting up blogs. I have the majority of two sites configured and ready to launch with some content, but wanted to know what you guys think of using pages vs. using posts in Wordpress?
What are the pros and cons of both from an SEO point of view?
Also, I'm having a hard time with one of the blogs just returning
"Not Found. The requested URL..." type errors when clicking on any of my posts or pages in one of my blogs. I have Googled this issue a bit and it seems to be a common WP problem, but from what I can see everything seems configured correctly. Suggestions to this are also welcome.
Thanks!
