Welcome to the Q&A Forum

I want to run google campaign for adwords and I want to target keywords that my competitor is ranking for. How can I know what are the keywords that are helping my competitors the most. Is there some way so that I can know what my competitor is bidding for those keywords. I heard it also depends on the landing page quality. Please suggest the best strategy to run adwords at lower cost and yet perform well. I am willing to run campaign for this website .  It is basically meant to connect manufacturers representatives and independent sales reps to businesses. Any suggestions are welcome.
