- Are the pages being crawled by the search engines, or just the sitemap?
- Is your version of WordPress up to date? Have you validated your robots.txt?
- Are there any messages in Google Webmaster Tools?
- Have the pages completely disappeared from the results when you do a search for your specific domain?
- Do you have many (or any) backlinks to pages in the /blog/ subdirectory?
