Are my ads in a good position ?

I just added bidvertiser ads to my site – Krawk.net
My site is written in Ajax so when people browse the site, the ad wont change since it is in the footer, and the content is the only part that changes . Do you think the footer is a decent spot to have my ads since when you click a link at the top on my site, when the content is loading the footer rises to the top a bit. If this spot isnt good, can you please suggest a better spot :S? Since my site is written in ajax, will that affect how much I earn and how many people click the ads? Thanks
