Since I posted my Google Webmaster Tools impressions/clicks chart yesterday, impressions rose even more. Traffic seems to be settled though, so it's only impressions. Another thing that happened today is that my new site (like two months old) received a huge boost today (huge for its size that is).
All in all, I am actually afraid of getting happy and excited, because I now know this can be taken away from me at any moment. One good thing that happened while I had very little Google traffic is that I stopped worrying about breaking their rules. I linked where I wanted to link. I made sponsored reviews. I commented on other sites with my URL without worrying about how Google will see it. I bought traffic. I republished quality non-original content. It was liberating. Now I am back to watching stats and worrying about guidelines.
I wish to know what triggered that filter in the first place.
