I have the exact same experience in regards to keywords. Only difference is that some that got boosted are high volume money keywords and some that tanked are low volume ones. It just seems... random. My main general site writes about health and fashion. The thing is that most of the fashion keywords tanked as well. The site leans more towards health, but still has a lot of fashion content. So I can only think that whole sites gets "marked" or "hit", not just keywords or certain articles. Perhaps they see that I write more about health, so they put me in the health category and decide to tank my non-health keywords as well. It's all very strange and so are the results I get in Google. If I am searching for financial stuff on Google in my country, the top results are from computer forums. It's random threads where someone asked "is this bank good?" and a few short posts saying "yes, it's pretty good". At the bottom of the first page and second page you have websites dedicated to finance and they have great information on them. Yet they are getting beat by a computer forum.. Aaaanyway, enough with my whining. I am seeing a liiiiittle bit more traffic in the last couple of days. I have built more links and I have fixed so that each post shows date published, nothing else.
