Google SEO tips

I'm learning new things on how to make your page SEO friendly. How to get ranking etc. I'm very sure what i know is not even a fraction of how google search works. But here's an interesting thing I learnt. When you search - results are listed based on your location. if you are competing in international market and your primary audience are US based then, there is a way to get results listed like how it it viewed by a user with US IP.

After the results are listed, in the address bar - at the end add &gl=us (google location = united states) like wise you can add relevant country shortforms 'ca -canada, au-australia, in-india'. You can get a sense of your competitors in specific to that market useful when it comes to adwords.
