All countries are good to advertise in, but because of the economic climate you will find some better than others.
There are also some countries that have internet payment restrictions which mean people from these countries can not always purchase the items they wish to.
One obvious place to advertise is the countries where they speak the same language as you.
I know we have Google translate but it is not always as accurate as one would like.
English speaking countries are the most obvious choice as they are more likely to be able to understand everything on the website as it was written and not as it is sometimes translated into other languages.
If you choose to advertise in countries with a weaker or poor economy be sure to point out to them that they can join free and by promoting items can earn an income.
I hope this helps and wish you success in your quest
