Yesterday while doing training I noticed that Google was dropping the review shadow box from the main search results and taking users directly to the business Plus page. Today others are noticing this as well. Nicolai Helling pointed the new behavior out on G+.
As Nicolai mentioned and I agree this change “seems to be preparatory to release a new way to insert the Google+ Local results into the main Google-SERPs” that I wrote about early in the week with the total absence of review links in the new mini pack results.
Currently the review shadow box STILL shows for brand searches on both the link under the One Pack and in the Knowledge panel. But on Pack results users are directed to the Plus About page. On the current Carousel a click takes the searcher to a brand search.
While it is possible that the 7-pack will survive the carousel transition to newly seen Mini Pack, all of this behavior would be consistent with changing all local results to the new mini pack as well.
