If a page is PR 0, and not in the cache, it has probably been penalized, or at least not indexed, is that correct?
BUT what does it mean if a page does have some toolbar PR, and yet still is not found in the cache?
Someone please shed some light on this for me please :)
If page has PR0, it means it's not indexed, or toolbar PR database has not been exported since it was indexed (look for posts about how rarely toolbar PR is updated) or page has pagerank smaller than 1.0. If you read the definition of PageRank, described in the old Google patent, you'll understand that as PR is a kind of probabilistic distribution, normalized in web-scale, for every PR1 page there have to be certain number of PR0 pages, and even more for every PR2 pages and so on.
Many pages can be listed url-only, no matter they have PR or not. PR is based on inbound links, while existence of a snippet depends on page crawl. If page has snippet but no cache, it means it has noArchive option in meta robots. If there's no snipet at all, it means the page waits to be crawled (and it will be crawled sooner if PR is higher).
Other possible meaning is that page was a duplicate content - in this case pages sometimes go url-only too.
