Fair Suggestion I would say quit adwords if you are not so sure abot products and you do not want to put a lot in researching products as to see whats going to work for you. Well that true not every product works for one single person. Use free methods : blogs, bum marketing etc etc too many to list Then try the products that you are most confident about. Its hard to see first sale sometimes. Well all here know that once you see thatfirst one you will be dictating terms out here on DP. Start every day with fresh idea till you know a product and a trick that works. Good luck.
