This morning one of my sites dropped out of the search for about 45 minutes - it is in slots ranging from 1-10 for some good KW's. Then all of a sudden it came back for a while -- about an hour -- got the regular amount of traffic. Then just about 25 minutes ago it disappeared again. Are they shuffling or what ? The results of a search vary alot if you search when my site is up versus when it is down, looks like a completely different search.
I think i found the problem - the KW's were like rate me nude, rate me naked etc, for some reason when i clicked the link it was showing results with safe search on - you need it off to see my site. But the traffic is way down from yahoo so i wonder if the site just got moved to the area where you need safe search off to see it. Oh well
