You can look over the whole set of slides, but here are the five things that I highlighted:

• Google indexes content faster than ever.



• Google shows search results as searchers type.


• Google ranks search results based on social activity.


• Google ranks search results based on human ratings of Web page quality.


• Google ranks results based on who your friends are.

All of these changes have come in just the last two years and add up to some massive changes in the way search marketing works. Where you once could conduct link campaigns (or even break the rules by buying links), that doesnt work very well anymore, because if the human raters and the your sites social activity dont validate the link analysis, your site drops in rankings. If you were living off old pages and had ignored social, you might not even find your content showing up. If had good rankings for top keywords but not for the five-word long-tail keywords, you might be suffering, too.

What has brought on this frenzy of activity from Google? I think they have been running scared from Bing since 2009. Bing made massive gains in 2010"to the point that a few pundits were actually predicting that the trend showed that Bing would eventually tie Google in market share. But as these changes have rolled out, Google has stabilized its free-fall in market share, leaving Bing with a substantial 30% US share, but that number has not budged in a year.

Will Google keep innovating? Certainly. Google is worried about not just Bing but Facebook and other threats. And maybe it will even accelerate the pace. If you have a Web site, you need to familiarize yourself with these changes so you can understand the new ways to succeed at search marketing.
