Today the U.S. Department of justice filed a second antitrust lawsuit against Google, this one with the aim for forcing it to divest parts of its online advertising business.

That made me to wonder about the extent to which affiliates make use of paid advertising to drive traffic to their sites. Many of us rely solely on on organic search and free links to generate the traffic to our sites, but many of us also pay to help generate traffic to our sites. How about you. Besides voting in the poll, share your thoughts about whether you feel paid advertising has been or would be worthwhile or a waste of money for you.
