Assume we have a limited advertisement budget that we are currently spreading it across 30 countries.
Is it valid to think that by putting it all on a single country (e.g Italy) there is an increased probability that we'll go viral (in Italy) due to greater accumulated local awareness of the advertised service/product?
Edit: I'm asking something very specific here. Does it play any role if the people who are exposed to the product/service know each other in the hope that they'll discuss it and spread it to other friends? Or not? I assume that I have greater chances to expose the product to people who know each other if I spend all my budget in a specific country vs the whole world.
