When creating an adwords campaign you can use up to 3 types of keyword matching options. They are broad match, exact match and phrase match. If I have a list of the most common search phrases, which keyword matching option should I use? Or should I use all 3?
Depends on your goal. Try testing all 3 and see what converts the best. If you don't want to spend the $$$ testing start with exact match and work your way into the others when you see how exact match is converting.
