In our ongoing effort to help you find more high-quality websites in search results, today we’re launching an algorithmic change that looks at the layout of a webpage and the amount of content you see on the page once you click on a result.

It’s my opinion that if SPYW continues to roll out to all logged-in Google users and Google stays as aggressive as it’s been in the last 10 days with pushing Google+ for even logged-out users, the service will become a necessity for search and social marketers. In 2009 and 2010, Google’s integration with Twitter was remarkable – helping content get indexed in seconds, earning featured spots for logged-in users who were connected to each other on Twitter and showing up in all sorts of specially-marked-up results. Google’s taken that much, much further with SPYW, and while I’m no particular fan of using your market power to force users onto a platform they may not want, I’m also a realist.
