Well, I’m testing it on several sites, the first is for Kid Recliners and since we’ve added it, their serps have risen.
Next I’ve added it to the Nice Car Company,. http://www.nicecarcompany.com/ they are a great used car dealer specializing in low mileage one-owner used cars. Their micro data will list the year, make, model, sale price, image and url.
We shall see what happens with the Microdata car information.
