the site is stable but the blog ( a sub-folder of the site ) went to PR5 and even many of the individual blog articles now have PR2 - so do many deep links have PR2-4. overall a slight UP across many major pages and deep pages.
Mine went down from PR 4 to PR 2. But I finally made it to first page of my target keyword so I'm happy. I guess PR doesn't really mean high search ranking.
Well few of clients website got PR down by 1 on 28th Feb 2008. Recently i.e. on 02th May 2008, its updated & the lost PR is recovered i.e. +1 again.
My PR go from 3 to 4 so I'm pretty sure I'm doing things right! I tell my family I'm SEO expert...they say I suck.
