Take a look at the two screen shots below. The left is the new "3 pack", the right is a test of new google "home services" ads that will replace adwords for local seo. See any similarities? I believe that google cut down the 7-pack to a 3-pack so that 3-pack can be transitioned easily into a pay "home services" format they are beta testing. A live example of the "home services" beta test can be seen here: https://www.google.com/search?q=plumbers+in+san+francisco What do you think?
