My blog address

when i started my blog i didnt pay attention and and my blog address is to difficult to remember.now i have submitted it every where.i cannot change it what you guys think it will have a effect on my earnings.

 

There's no relationship of your url with earnings.

exchange rate does, especially USD to Euro

 

Yes in two ways ( according to my assumption)

First thing if it is too hard to remember people may forget and less traffic .
less traffic = low earning

Second thing - the Url sometimes matter with ads -
what i means the ad targets as per the url too ... so ecpm may be low for that particular keyword

so low earnings for second possible way too..

 

just like sairu pointed out. It will have a negative impact on your returning visitors.
