Explorer ranking against firefox
I am new to website building and have just launched my first site 8 weeks ago, I did not use any web builder as not got the money, at first my site was not even reconised by google .then someone told me about firefox and when I put my name in, it is double the figure than Internet Explorer,I do not use SEO companies, will my ranking improve if I stick at it , or do I need to use an SEO( not even to sure what they are) and what is the most used IE or Firefox
