One of my sites, i doubt is in sandbox. but can sandboxed stes have PR? mine has a PR1. but the sites pages are not geting indexed even though googlebot visits them.
I have pages that have PR4 but no-where to be found since I built them. Links are still collected (link:%myurl%) though they do not appear in allinanchor searches. I don't know if it is called sandbox but it is something that affects my pages since they were born... So I think you're in my same boat
my site is pr4 and is sandboxxed or in the google pub or lost maybe all 3 but yes sandboxxed sites can have pr and everything else a normal sites has exept from the high rankings
My site does NOT appear in searches. only links and indexed pages appear. Not even allinanchor searches show my pages
my site does appear in google searches but for "really long keywords like this" or for keywords that have under 50k competition. it also ranks well for allinanchor searches
I have a site that is a PR 6 with 1500 PR 5 pages, all unique content that is hard coded, and perfectly optimized. Yes, I am in the sandbox too, after 10 months.
