Take a look at this article http://www.seroundtable.com/google-penguin-update11-15146.html did you notice any ranking change since yesterday? I checked mine, still has not recovered from penguin yet. How about you?
I've slowly seen sites that dropped in rank move back up the serps, but yes, I must say there was a measurable difference over the weekend.
Google is a Mother for making an update on Mother's day, lol. I still think the best things we can do is keep working at legitimate SEO.
