Do you use a universal link for the promotion of your kindle books? I was not, but hereafter I'm going to use it. Many times we post links of our books on our websites or for twitter promotion with just about one store link. i.e amazon.com or amazon.in etc. If we post links like this, some smart ones may change it to buy from their country's site. Others may not even check it, thinking that it is not available in their country. Thus, you are likely to lose your potential customers from the other parts of the globe. If you have made your kindle book available worldwide the best thing is to use a universal link, so that your potential customers worldwide can click on that link and they will be able to find the correct store available in their country.
