Hi Guys, I would need some advice on my directory at www.nznp.com It used to have a PR of 4 and had over 600k pages indexed with Google. Now after the recent PR update it dropped to PR0 and has currently just over 3k pages indexed. The only big change I had was a complete re-design of the site a few months ago. Googlebot is spidering daily and webmaster tools on Google sitemap doesn't show any major problems apart from a handful missing pages. I have no idea what's gone wrong on this one. Thanks for your help!
Yes, I imported many of dmoz health related sites when I started. The directory has nearly 6k categories and each sites listing has 3 seperate pages.
