When someone in Algeria clicks your ad, is the website and product they find written in Arabic, their official language? Does the pricing reflect the potential customer's average salary of, at most, several hundred dollars per month? If not, why would you expect them to buy from you, even if you do happen to have other customers from Algeria? I have customers in many countries as well, but that's because they happen to be English speaking businesses with international client bases, which means their budget allows my type of service. If I were to advertise to those same countries, though, 99.999% of the people my ad reached would neither be able to read nor purchase the product.
