i get some leads from google but majority of them are not from the countries that i would like to target just curious to know are there any method to target searchers of a particular country such as US and canada? (exclude by using adwords)
You can capitalize on unwanted traffic by plastering ads on the page dynamically, also mentioning in a kind way that you don't serve those countries. Yuo could also SEO for regional searches, involving locations in the phrases. Depends a bit on your offfering whether that's of any use or not.
