Penguin & Panda: Geographic Penalities?

[Prospector-Plastics]

Has anyone ever come across information about a website appearing strongly in SERP's in one region, but poorly in another? (ie: great in Europe, not so great in N. America)

If so, perhaps it is a Panda or Penguin issue?

There are many factor which influences a site's ranking in one region or another.

Google is heading toward personalized results based on user location, but that's no panda or penguin issue.

Some things to consider are:

• the location of your hosting server
• the tld of your site
• the location and tld of your linking sites
• the location you set up in your gwtools or in your buiness page
• the content of your site, if it's english it may be more british focused or american
• and other ranking factors which only google knows
