A Google Webmaster Help thread once again confirms that Google ignores the geo-meta tags. Those tags somewhat look like this and use to serve the purpose of telling search engines where the site is based:
<meta name="geo.placename" content="United States" />
<meta name="geo.position" content="x;x" />
<meta name="geo.region" content="usa" />
<meta name="ICBM" content="x,x" />
Google ignores them, and has for a really long time. JohnMu from Google confirmed this most recently in the thread:
We generally ignore geo-meta tags like that because we've found that they're generally incorrect (copy & pasted from a template, etc).
But we had confirmation of this when wrote that Bing relies on these geo-meta tags to determine a site's location. And time and time again, there are webmasters who find there site targeted to the wrong country because of that template issue. In that post, Google's Matt Cutts said the same thing:
Historically, meta tags for language and country have been less reliable than inferring the language or country directly. For example, lots of webmaster also just copy/paste from a friend's template without checking the meta tag values. The unreliability of the meta tags is why Google tends not to use them or give them less weight.
So three webmaster points here:
(1) Google ignore the geo-meta tag (2) Bing currently uses the geo-meta tag (3) Be careful when you copy templates or use pre-existing templates

What is the ICBM tag for? I assume it's not intercontinental ballistic missile...

Michael, it looks like it is indeed from the old ICBM missile address. see the history here : http://www.catb.org/~esr/jargon/html/I/ICBM-address.html -- I find it sad that we cannot use this nice way to share information just because too many people make mistakes !! Ford didn't stop to make cars because people crashed them, he added seatbelts ;)

A good seatbelt in this case could be to include the address of the file the meta tag applies to, so a copy paste would show the wrong file & be easy to detect. Kinda wasteful of space, but then seatbelts are inconvenient to put on, but worth it ;-)

is better to put geo meta-tag to your website, not for google, because google ignore this meta-tag, but for another search engine , like bing, this meta-tag metter http://mitrovici-seo.blogspot.com/2010/07/google-ignore-geo-meta-tags.html

There are sites available that will generate the html for you and show where the co-ordinates point to on google maps so you can't go wrong. Try mygeoposition.com.

Great article! Thanks! I guess that Google doesn't currently rely on GeoTags but with the increase in small shops that are starting to offer services on the social web and the whole "geolocation" google might soon start doing the same. Better to be prepared... Plus its only like 4 lines of code.

Thanks for the post. Even if google does not consider geo meta tag I think it is better to add if another popular search engine Bing uses it

I wonder why Bing tends to use this, since they should be able to detect the target country and region by looking at the website content, domain, language and server IP. I guess Bing does a fallback check/guess, if it is not provided, since most websites dont set or use this attribute.

Data on the geo location of the site is useful information and should be obligatory items when creating code. Thanks for post.

I use Typo3 and an extension called tq_seo which gives the opportunity to use easily the geo positioning option - then I realized that Google is not giving so much weight to the tags. But better to have it and not need it than the other way around. Thanks for the info.

If you are using WordPress, the easiest way to add the tags is to use mygeoposition.com and then use the WP plugin: http://netweblogic.com/wordpress/plugins/meta-tag-manager/ to add the relevant meta-tags.
