I have had some huge boosts and most of my sites have gone right up. I even had a directory using the link bid script which i started up for a joke. I actually abandoned it 1 week later and thought of it as a $30 loss (i.e. script cost).. Even that went straight up to PR4...
PR 6 down to PR5 (online shopping site) 3years PR 0 up to PR3 (Music Streaming Site) 1year PR 7 down to PR5! (Web design firm homepage) 5+ year
PR +2 on most of my sites. Even trashy sites got 2 points. It's weird since I barely worked on link building.
Main site back to 5. Was 5 for yonks, 6 for a nanosecond, then 5 for a while, then 4, now back to 5. Getting dizzy!
