title: Which one is the right way to add geolocation meta info to a site?
body: <p>I'm looking how to add meta info to a page.
  One way is the meta tag</p>
  
  <pre><code>&lt;metatag name="country" content="Canada" /&gt;
  </code></pre>
  
  <p>another I saw is</p>
  
  <pre><code>&lt;metatag name="geo.country" content="CA" /&gt;
  </code></pre>
  
  <p>using the ISO 3166.</p>
  
  <p>I like the second one because is standard with ISO and easy to understand by crawlers.
  Which one of these options is standard? Or most of the crawlers accept them ?</p>
  
  <p>I know that Google does not use any of them, but Bing does.</p>
  
  <p>One site is for desktop web browsers and another one is for WAP (mobile) browsers. Is there any difference?</p>
