for affiliate marketting by google adwords, is it necessary to have my own webpage or i can send the people directly to advertisors
Not only is a webpage (blog or website) necessary, it is the key to the success. Building a webpage full of valuable content is what drives targeted traffic to your site and will get people seeking more and in turn click on the affiliate connection. I have some great information that surrounds this topic. I would be happy to pass it along. If you are serious and want to do research, feel free to contact me through my profile.
