A few weeks ago Google released an algorithm update called “Hawk”. The update is focused on local search and shouldn’t have a major effect on other search efforts.
It helps Google filter results by reducing the size of the geographic area that it controls. That means it does a better job of assessing those businesses that seem to be the same in of industry and geography - and yet are not.
This assumption that it is the one business listing themselves multiple times impacts businesses such as restaurants and hotels, as well as medical professionals, tradesmen with offices, and other shop business that tend to cluster in location.
While, some businesses may still struggle, like those that share office space, the majority of businesses will be much happier with this iteration of Google’s local search.
