Google Maps: KML for authority and ranking?

We know that Google is using KML files and Geo Sitemaps to establish location and legitimacy for bricks and mortar businesses. Could it also have more importance on ranking than we currently know?

Carter Maslan, VP of Maps, has indicated that businesses should start using KML files in his interviews with Greg Sterling & Eric Enge.

Eric Enge: I first heard about KML a while back and I have seen some stuff suggesting that KML would allow you to provide a deeper level of metadata about your business. I believe people have talked about using this within the context of the sitemap files, is that something that is useful for people to do?

Carter Maslan: Yes, it helps a lot in knowing the precise geographic location that is being described by a page so it is definitely good to have a sitemap that references a KML file with an accurate description of the entities referenced geographically.

Eric Enge: Right, the sitemap file is something that is authenticated, and therefore the KML file would be by implication authenticated.

Carter Maslan: Correct. It helps both from that perspective and simply just knowing that there is additional information about that place, and that it is also correlated with that web page, helps.

As Martijn Beijk pointed out in a previous comment: if the Local Business Center = 2, then a Bulk upload +KML file + a geo sitemap + Webmaster Central = 2 as well. Whether that math is exactly correct, KML process does seem to convince Google of the legitimacy of a bulk upload and increases the authority of the business listing in Google’s eyes.

The KML process should be a standard part of the Local Search Marketing arsenal when using bulk uploads to create business listings in Maps.

Martijn has written an excellent tutorial on creating a KML and a GeoSitemap for Google’s Webmaster Central. I tested Martijn’s process using the Mike Test to determine if I can learn it or not. I can report that it passed my test.

Here is a summary of the steps involved to complete the needed steps:

1)Create a KML file using something like Google Earth. I used a Mac program called HoudahGeo which has the added benefit of geocoding and uploading photos directly to Flickr.
2)Upload the KML Files to your server. My KML file is viewable here.
3)Create a Geo Sitemap using this sample code, inserting the URL of your KML file in the geo sitemap.
4)Upload the geo sitemap to your server. My geo sitemap is viewable here.
5)Go to Google’s Webmaster tools and add another sitemap to the domain and indicate to Google that is it a Geo Sitemap

Upload geo sitemap to Webmaster Central
6)For good luck, create a link on your website to the KML file for other spiders to find it

We know for sure that this KML process should be used for businesses that are doing bulk uploads and want to communicate the legitimacy of their listings to Google . However, its importance to Google and Maps Ranking is still not fully known. It is unclear whether KML files are used by Google to impact rank or not.

We do know that Google has started displaying user generated content in the business listing in Maps. User Generated Content is essentially KML information that has made its way into Google Maps. As a side note, the KML created above can be easily imported into MyMaps.

We also know that Google is indexing and storing the geo web made up of KML files and geoRSS feeds and has been doing so for almost a year. Given Google’s history of looking to the greater web for an indication of a websites popularity on the WWW, it is not too much of a stretch to assume that something similar is happening with the geo web.

The complaint has been raised that KML is not understandable by the average business person. That may be, but it has always been the case that new technologies take awhile to understand and implement. If it can pass the Mike test, it is getting ready to enter the mainstream and is certainly capable of being done by search professionals. KML is one of those techniques that needs to be studied but with a little study can be implemented now and is clearly beneficial in certain uses cases. Even if it has no impact on rank it falls into the “it can’t hurt” category for other users.

We don’t know for sure if it impacts ranking but if you have seen clear indicators that KML files do impact ranking, I would love to hear from you.

  1. I know the Mike test suggests that anyone can do it. But the real test is if it passes the “dave” test. If it does then it is definitely idiot proof. I’ll give it a try and report back later. :D

  2. Now let me see….if I agree with you I am being disrespectful and if I disagree with you I am being disrespectful…hmmm best keep my mouth shut. :)

  3. Excellent summary, and thx for the appreciation! Glad it passed the Mike Test.
    From the screenshot you are showing it seems that Google now has implemented the geo sitemap feature in their webmaster central. At date I wrote the tutorial I seem to remember that it was still ‘additional generic sitemap’. I wonder if their help documentation is updated already.

  4. Hi Matt

    Great question. I agree wholeheartedly.

    My programmer tells me that it is fairly simple to write the KML and geositemap files out if your business listings info is in a database.

    He also told me to tell you that if you need a programmer he is available :)

  5. Interesting thought, very interesting. I’ve been looking at ‘tools’ as well to do bulkybulk conversions to KML if data is available in a database. Maybe going to write one myself as well, but something for the future.

    One question rises though, how do KML affect ranking or authority in that manner? whats the benefit for a SMB to have a local directory host a kml, and not themselves? or would it just be a matter of; the more geoinfo available, the better?

  6. @martinj

    Two big directories that do so are Ibegin.com and Merchantcircle and those kml files show up in the user generated content tab in the business record in Maps…so in theory they have some value.

  7. Hi Mike

    Thanks, that’s a very useful overview. I’m in the process of working out whether setting up KML and geo sitemaps would be a useful service to offer our customers, and your article helped me to understand it much better. I’d guess it’s one of those things where if two businesses have roughly equal factors affecting their place in the “ten box”, having a KML file might just tip the balance determining which gets ranked higher?

    Thanks again, Jon

  8. Hi Jon

    I have as yet not tested whether it will lead to higher rank but you are right that it might lead to some edge. Now that Google is showing this info in the User Content tab, they are obviously indicating that it is important information. We just don’t yet know how important.

    Mike

  9. The article was very insightful. Noticing more “User Generated” content in Google Maps and was researching how to perform bulk uploads to Google Maps. This information is golden for local search. There really is not much info about ranking in the “ten box” which is very surprising. We will see how this works. Thanks.
