Today we’re going to talk about how do meta geo tags influence search results
It is not something that we look at very closely at all. Not meta geo tags. We tend to look at the IP address, we tend to look at the gTLD or the ccTLD, that’s the country code TLD (top level domain, so .fr, .de). There’s also something in Google’s Webmaster Tools where you can say “my site is not just a .com that’s about the entire world, it’s a British .com. Or it’s a .com that really pertains to New Zealand or Australia”. So, you can highlight and say, okay this .com is really about Germany or Canada or whatever your country is.
Typically the meta geo tags are not as useful and we don’t tend to give those as much weight, if at all. So, I would spend your time trying to make sure you have the right domain name, trying to make sure that you have the right IP address if you can, and then definitely if you have content that’s geo-located; even if it’s a subdomain or a subdirectory, you can specify that within Google’s Webmaster Tools and say “yes, this is relevant for this particular country”.
