One of the most important developments in Google's evolution in 2012 was its change to local searches. The organization considers nearby results a priority, which is why it now makes local queries the default setting for all users. This can be cause for frustration among businesses attempting to locate clients through search engine optimization, especially since Google keeps tweaking their local search algorithms.
The recent March 2012 alteration is being called Google Venice, and it penalizes national companies that provide local services, including dentistry, financial consulting and similar business. The most salient effect is that organizations without local addresses won't appear in some search results for users who haven't turned off their localization settings.
Businesses operating on the internet shouldn't have much of a problem because of Google Venice, and companies confined to specific geographic areas don't have cause to worry. However, organizations that maintain multiple offices in different regions need to update their contact information and geographic settings to make sure Google understands they operate locally rather than nationally. If not, they risk suffering in terms of search engine optimization.
