It appears that Google has again increased the search radius for a large number of “search phrase + city” searches
Since the spring of last year, Google has been reducing the radius for displaying results on many local searches. Effectively this meant that businesses outside the smaller radius would no longer show a pinned result. I had investigated this problem in searches as varied as “Jewerly Buffalo NY”, “Personal Injury Attorney Anchorage”, “Bankruptcy Attorney Charlotte”, “New Orleans Divorce” and “DC Accident Attorney” amongst others. In each of these cases businesses that had once shown up in the Google Places Search results were no longer found. Frequently they had dropped as many as 40 or 50 places on their head terms only.
Uniformly it appeared that Google had increased the “location sensitivity” of the search limiting which businesses would be seen. This affect has been noted in a number of industries and Google had spoken about their testing of this on NPR.
Brian Combs of Ionadas.com alerted me that the radius had once again increased to show search results from a much broader map area. In the five cases that I had looked at, the businesses that had been dropped with the decreased radius, once again showed up on the map and in the search.
Here is an screen shot of the map that showed for the search area that presented during last year and the search area presented as of yesterday on the search “Jewerly Buffalo NY“. Note the dramatic increase in distance from the centroid and the number of included pins in the newest results. Under the previous reduced radius only businesses in very close proximity to the centroid were shown. (click to view larger):
Linda Buquet documented the reduced search area in her October post Google Places Algorithm Change – New Proximity Lockout Algo Can Cause Major Ranking Drop. The reduced radius had also been noted by Andrew Shotland in June of 2011. The reduced radius appeared to rollout in different markets at different times but its return has occurred on all of the searches I examined simultaneously.
