The thing I always suggest when people talk about Google algorithm changes and instability in how sites are ranked is to simply go back to basics. Publish highest quality articles on your blog or site, update daily if needed. Add new content to old posts and pages, make things interesting for your readers (Google loves it when you cater to your readers). And, just keep going at a steady pace. Google will run to catch up with you. Also, don't forget to constantly reread the Google Webmaster TOS help pages. They contain a ton of great info on what you should be doing now. Sometimes a good reread will glean new info you missed first time around.
