The url-only problem [webmasterworld.com]
However, what is the best way to request reinclusion? Can I simply resubmit my Google Site Map from the webmaster center or do I have to request a normal url inclusione request waiting months to see my pages and my pr back?
in google index from 1999
One of the things that has happened this year is that "everything changed" on Google. When they migrated to their new Big Daddy infrastructure, they began new crawling patterns and are apparently using lots of rewritten code. It doesn't always work the way we're used to. There appear to be some technical assumptions about website coding, urls and so on, that are a bit more demanding and precise than their legacy code was.
And from time to time (even right now) the site: operator has given odd results that do not always reflect what is showing in regular search. So it's important to give your site a technical health check-up - something like doing physical for your bodily health. Things that never seemed to be problematic in the past may now be causing trouble.
I'm not sure if this was an intentional change on Google's part, or if it was just one of those things. But one thing is for sure -- it's what we have now. The threads I linked to above will wade into some of the details.
