What are the benefits of marketing acrss international borders?

More specifically, i am interested in learning about any problems that a business can incur in advertising in a host country, say in Europe, and how can these problems be addressed.

Wow. Your problems will be many in advertising in another country.

I won't even touch on the International currency, laws, fees, etc.

Focusing on marketing, if you are going to have creative input on your advertising, you are going to need to understand your market and being raised in a different culture, you may have a difficult time doing it.

Pick your product ... pick at your country and then your locale. Research it well and look at the motivations of the people in your target area.

Look at the backgrounds of the people in your target market.

Wirte your marketing plan and, if possible, get it reviewed by someone who knows the country. At the least, put it on Answers and get input from us!

Good luck.

You can get some good education and resources on marketing internationally through the Direct Marketing Association. Browse their website at www.the-dma.org

Or, think about attending their annual conference which features international exhibits and sessions.

I wouldn't know anywhere else as reputable as the DMA to get this kind of info.
