I did some Energy Diary program which is aimed first of all on US market. It is because I think there my program may help to lot of people and its database of foods is from USDA nutrient laboratory (that means there are foods mainly from USA). Problem is next: I did promotion page, for this shareware, and I register it for Google Analytics service. Here it is possible to see from which countries are people visiting these pages. After 2 weeks I am surprised that a lot of people is from Asia and Europe, but only small part is from USA. I registered this page in many shareware lists of course. I didn't make some SEO for my pages now. My question is How to increase part of visitors from USA, for my pages? Thank you for your advices.
I would suggest a PPC campaign with a combo of AdWords & Overture. You can specify the country, or go even further and specify only a certain ZIP code in the USA, where your ads will appear when someone searches for related terms. Other than that, I suggest an E-Mail marketing campaign, with emails sent to opt-in lists with the subscriber demographics of your choice (in this case, US based).
Write content for Americans. Remember we are in a globalized world so even foreigners might be interested in US products.
I have not problem with globalization. I am not from USA, and I will be happy when my program will be used everywhere in the world. As I wrote above, database of foods used in program is from US organization, and it contains foods from US food market mainly.
