Yesterday Greg Sterling had an Interview With Google’s Carter Maslan about Mapspam in which Google noted that they are still at the stage of removing mapspam by hand. Also of not was that they will be addressing how to allow non bricks and mortar locations to provide information on their service area (see What Should Google Do About Mapspam? from last year).
Of most interest to me, however, was the clear statement that all websites should have a KML sitemap to clearly indicate to Google the exact locations of your businesses:
SEL: What about a business that formerly appeared among these top 10 listings and no longer does or wants to appear in those listings, what advice would you provide to such businesses?
CM: As a result, there’s no one piece of advice we would recommend beyond providing accurate, well-categorized listings and, for those businesses with web sites, following these tips including location kml in sitemap.
It has been clear that Google has been scouring the web looking for and indexing KML files and it stood to reason that having a KML file associated with your website would give Google clear signals about your physical location.
The time has come for it to be considered a “best practice” to include a Geo Sitemap on any local or regional website. Google clearly wants webmasters to include this indicator of location in a clear and obvious way that allows them to easily confirm geo data. Details on how to create a Geo Sitemap can be found in the Webmaster Help Cetner file: How can I create a Geo Sitemap?
