Let's say you live in country A but want to promote a product in country B. When you want to research on Google whether this product could be in demand in country B or not - you type in the keyword and all (or most of) the sponsored results are shown from country A because that's your default location and that's where you are searching from. This happens even though you have checked "search the web" option rather than "pages from country A" in Google. So, How do you guys research for a particular product in a given country? Any help appreciated!
Mostly, I use adwords to test. Spend a bit of money learning if that product has demand. Adwords is cheap but most importantly - instant. You can literally find out within a week if a product will be in demand. Adwords can target by country.
country specific search can be done in the search engines. I believe the data centers group such data.
