I noticed today that 3 of my website's have dropped off serps (and 1 before penalized site came back up). Is there a some kind of update going on? Other reason, but seems rather quick from google, would be dance, since yesterday I added quite strong image sidebar links from relevant sites to all of these sites today moved a lot. Majestic stats for those sites I got backlink fr were Trust 25-35, Citation 35-50. Can single blogroll cause dance so fast?
