first of all, sorry if I create this thread in the wrong section I have 2 problems with my blog, first of all, why all my BL keep deindex, I've been trying to add BL regular via social bookmarking, profile bookmarking n article marketing, but none of them are getting indexed by yahoo, except from hubpages and ezinearticles only, other than that was zip n my BL keep decline I've been using backlink indexer service and still no result, no additional BL been indexed by yahoo is there anything wrong? and it happened to all my blogs. second is about my blog, this one is pretty weird, sometimes it shows up at rank 10-30 but sometimes it shows up at rank 600-700, it happen every week, in 2-3 days it will show up at rank 10-30 but the next day it will disappear again, n if i check using MS rank checker it will show up at 600-700, but after 2-3 days it will back again, this blog has PR 3, and age 5 months, is it sandbox? I don't think so, but if it is google dance, why it always happen every week and with the same pattern? about BL, it happens with my previous problems, it won't getting index by yahoo so can anyone help me with a solution?
What you need to do is think about your environment and link building techniques. Are you hosting all of your blogs on the same server? If so maybe you should try splitting them up. If you are using a backlinking service, maybe that's your problem.
