Hi all I have a us based ecommerce site...i want to know that wat are my SERP positions in us states so that i can improve my rankings and wat are the positions of my competitors in usa SERPS. I am already having 500 data centers of google but i can't differentiate those according to us states..how to find a IPs geographic location or is there any information avialable in the Internet on GOOGLES GEOGRAPHIC BASED DATA CENTERS ? If you have any info on Geographic based Data centers list can kindly share with me. why googles SERPS are not unique..why they change according to GEO Location ? Kindly share your views.
just think it in this way, they want to give you the result that clostest to you as much as possible. more servers are good to give you a better speed of generating result.
