Yes I know that a dot com is probably more memorable than the other extensions. but with the extension market widening, How can domain name registers keep up the price differential.
For instance a random url on godaddy with a dot com costs A$10.94*/yr while the dot biz costs A$5.46* is this just raw supply demand at work? Surely it doesnt cost the register company any more for their automated program to sell it to you?
I hear over and over how seo people say there is no difference regarding what common extension (not edu and gov of course) will provide you with in the opportunity to rise to the top, so is it just that people remember dot coms more?
