We believe that Google is running a large-scale test right now which is why there are at least three different versions of the Search Engine Results Pages. Most likely within a few weeks, that will be concluded and all SERPs with maps (Places) listings will be fully integrated.
What does this mean?
1. If you are in local search, it becomes MUCH more important that you have Place pages with correct information.
2. It becomes essential to have at least one image on your Place page, so that a thumbnail shows on the SERPs, giving your listing much more emphasis.
3. It makes Reviews a much more important subject. A systematic approach to getting positive reviews and ratings onto your Place page is now essential.
4. Because national companies won’t have a local Place page, it will be harder for them to compete with local companies in each locale.
5. Some businesses will be DRAMATICALLY affected by this change. Not all by any means, but some may see a huge increase or huge drop in traffic to their sites.
More to come….
