Got tipped off to this one at a recent event. I don't know if any or all of you have seen it or played with it yet but I invite everyone to check it out and let me know what you think the SEO implications will be.
Go into Google and search for anything (I looked for espresso machines). In the blue bar just above the search results you should see a link that says 'Show Options'. Click on this. You will get a menu down the left hand side and . Select Wonder Wheel. When you get the Wonder Wheel, click on one of its spokes and watch what happens to the search results to the right of the wonder wheel. Pretty cool. But what will the SEO tactics be for this?
