I just wanted to bring up a very interesting thing that has taken place with the switch to local listings displaying 7 instead of 10 results. Now, when the lucky 7 pack shows up, The number of reviews are all in line, and fall at the end of the listing. So, it is easier to shop by the number of reviews. For instance look at the example below.
Sys Storage, which on this search term is positioned at “D” , is the only company with reviews. Since the launch of the 7 pack, this company on this search phraze has seen a much higher Click Through Rate. I am convinced that it is due to the easier to compare reviews. So, start bring them in, Reviews are starting to gain a bit more momentum with every thing Google is doing.
