Many members in the forum seem to have liked Google Adwords. But, I am wondering if this tool really works. Many of them say that it brings in quality paying customers to a site. But, I do not understand how many of the net users actually check Google ads. Is this medium good for SEO? I feel that we are just paying too much for this service. I am dubious. Does this actually bring in traffic to the site? My friend had run a campaign that was really expensive. Plus, there was not a single visitor on his site. What is the use of this tool?
