On www.webhostingbreak.com I have custom post types for web hosting companies. Their url is /hosting-directory/ and unfortunately, since then (aug2010), we've still got all those pages at PR0 and rankings overall have been terrible.
The only guess I have is that because visiting /hosting-directory/ causes a 404 error, Google might not see pagerank flowing from the root domain to a subpage of hosting-directory.
We want to remove /hosting-directory/ altogether. We tried doing that but we couldn't get normal posts in a category to work.
Is there any workaround for this? Custom post types destroyed our rankings and pagerank since august 2010.
Be well and talk soon.
