Meta tag for geolocation

Question

I was looking for meta tags for geolocation, to help search engines know that the information on my site refers to a specific city.

I found this website which generates the following tags for an address I typed:

<meta name="geo.region" content="US-VA" />
<meta name="geo.placename" content="Fairfax" />
<meta name="geo.position" content="38.844573;-77.286766" />
<meta name="ICBM" content="38.844573, -77.286766" />

I searched the www.W3.org and in the www.w3schools.com something related to these tags and did not find.

These tags geo. are there effectively? Are they in development? Search engines interpret them?

Answer 1

I’ll answer as far as I know about your question, haha Google, which owns 45% of internet searches, does not recognize this meta tag. The ones he recognizes are here: https://support.google.com/webmasters/answer/79812?hl=pt-BR I’ve seen people using these tags (although I don’t know much about them) and if they’re really useful to your project, use them!

Answer 2

Apparently based on the answers given and links provided, these metatags not considered by all engines, mainly by Google, as answered by Giancarlo Soldera Graziano, and there is little material available on this.

The reason I wanted these tags is in the original question:

....to help search engines know that the information on my site refers to a specific city.

Trying to find the answer, I came across another concept: structured data. I know I didn’t ask about it, but it’s because I didn’t know it existed, and that’s actually what I was looking for, but I didn’t know.

Using structured data, I can indicate to Google (main search engine) valuable information about my site, including the latitude and longitude that was asked.

That one website generates the structured data script. It will give you a script of the type application/ld+json that you put on head from your page. Here’s an example I generated on this site:

<script type='application/ld+json'> 
{
  "@context": "http://www.schema.org",
  "@type": "Bakery",
  "name": "Minha Padaria",
  "url": "www.minhapadaria.com.br",
  "description": "Essa é a descrição da minha padaria",
  "address": {
    "@type": "PostalAddress",
    "streetAddress": "Rua da Padaria, 29",
    "addressLocality": "São Paulo",
    "addressRegion": "SP",
    "postalCode": "00000-000",
    "addressCountry": "Brazil"
  },
  "geo": {
    "@type": "GeoCoordinates",
    "latitude": "38.844573",
    "longitude": "-77.286766"
  },
  "openingHours": "Mo, Tu, We, Th, Fr, Sa 06:30-20:00",
  "contactPoint": {
    "@type": "ContactPoint",
    "telephone": "[phone]"
  }
}
</script>

There are other sites that generate this, like:

Answer 3

From what I researched the tag exists, the point is that it is not an official standard.

In Wikipédia explains a little about the pattern: https://en.wikipedia.org/wiki/Geotagging#HTML_pages

Due to doubts if your project will benefit from this information is interesting to use even if not all the searchers use it yet, so when using your project will already be working with it.
