Ok, this has been confusing me for a bit so I thought I would get some advice/opinions. I have a handful of sites (all unrelated to each other) which are starting to drop in search results on Google, while at the same time their MSN rankings are increasing. It started off with one site which Google ranked at #4 dropping to #50 and then to off the charts 30 days later for it's main keyword. Initially I thought no big deal, sites do this so I continued building links. Now my other sites are starting to do the same thing and the first site has yet to recover any of it's previous rankings in mid July. My linking strategy is getting 90% of links from 3+ PR do-follow blog comments. I'm leaving manual and relevant comments but am using the keyword as my name to link back to my site. So what is anyone's opinion on what's going on? Am I just being impatient waiting for Google to update the site rankings? Am I doing something wrong because my other sites are starting to decrease in ranking like the first site? What would you do?
