I use market samurai to check my rankings (so i have the results from firefox because it is the default browser) . Using different browser get different resutls and i cant understand the reason and what are the real rankings. So let's see an example Keyword1: Google Chrome: rank 11 Internet Explorer: rank 2 Mozila Firefox: rank 2 All searches have the same settings for region etc... In this example 2 of them have the same ranking. But in other keywords i got 3 different results one for each. Why is this happening? It is normal? I will try to use my Ubuntu 11.04 to see the ranks there too, but i'm a little bit confused from this mixed rankings!
