Update: I just noticed that David announced the results of the study on his blog, too.
Today I was planning of posting the next part of the Local Citation Building Study (you can see parts 1, 2, 3, and 4 in the meantime), which covers the best local business directories for Australia, New Zealand, and Germany. However, a tweet by Phil Rozek made me change my mind.
Phil pointed out a new resource on the GetListed.org directory, which features one of the most thorough list of local citation sources I’ve seen up to now. David Mihm and Darren Shaw researched “71 local search categories across 53 large US cities, 20 medium-sized cities, and 20 smaller cities” and came up with the top 10 citation sources for each of them by city. I had previously done a much smaller scale research of industry-specific directories, but this is something really impressive and a bit of information everyone doing local SEO should refer to.
My initial observations are that YP.com is owning a large part of the top positions, followed closely by Yelp, and distant thirds seem to be Citysearch and Superpages. Additionally, full list for each of these cities is available on Whitespark’s Local Citation Finder. Today I managed to peak at this data, but unfortunately ever since then Whitespark’s server seems to be overloaded.
We will definitely be using this data as part of our local citation building service when determining the most suitable citation sources for each business.
