Freshness of content is the new king

Is this the end of the Google dance as we know it? Many users complain lately that their placement in Google results page fluctuates daily. It could be a sign for a coming algorithm update, however it looks like the update is already here. I can only speak for my own sites but it is not hard to notice that lately they are indexed daily or more. Each post I add change my placement in Google's results page. Failing to update for a couple of days will result in a drop in placement. The only way to explain this is that freshness of content is the new main factor in Google's algorithm. In addition, your SEO efforts show results much faster now. Since the changes are daily, the updates will be continuous. Take a non-competitive term and see how each update in your page will change your placement, almost immediately, in Google's results pages.
