I noticed a site show up in update Cassandra that didn't hav any PR or a cached version but had great rankings on relatively competitve terms. This update the same site seems to have been deep crawled yet still no cached version is showing up. I can understand that there can be glitches in PR but the cache?
The site seems to be using a real heavy link density formula which makes the site look spammy but it's getting a lot of good, free traffic. Anyone have any idea how or why this might be happening?
