I searched for a keyword today and was happy to find a client's website on page 1 result 1 for that keyword. Then I told my bf about it, and he checked on google, he can't even see the website in the top 5 pages for the keyword. We are both not logged into our google accounts, we are both using google.com and not using any filters but why different results? I changed my IP and tried again, I am still getting page 1 result 1. Then I used a proxy server and this time like what my bf has mentioned, the website is nowhere near page 1 for the keyword. Any explanation to this? Is google showing results based on IP or computer name?
