For all of my keywords, mozilla shows a different SERP than IE...so on mozilla one keyword shows on the second position. then same keyword, I'm on the third page for IE.....what's wrong, my computer?
Which search engines were you using? Google displays you user agent in the browser bar as part of the search and that could affect the SERP but haven't heard of anything like that happening.
I was using google. The strange thing is I tested the same keywords on firefox using google on my laptop, and on my PC. same SERP for the same keywords. Then I go to my school using firefox, typed the same keyword in, and it my site wasn't on the first page anymore...
