I felt it necessary to mention the Adwords program because the quality of their Pay-Per-Click traffic
is the benchmark for Internet Marketers to measure targeted traffic with. Almost nothing else can compete with AdWords as far as targeting, because they not only serve the AdWord advertisement boxes on relevant, keyword-targeted pages across the web, but in the Search Engine Result Pages as well.
eBay’s traffic is the notable competition. Although eBay is not as precisely targeted as AdWords, nor can it bring as many visitors as quickly, eBay triumphs in delivering visitors in a buying state of mind… And you can get those visitors for free through eBay.
Expect to pay a very minimum of five cents per visitor through AdWords, but usually more likely around $1 with more competitive keywords costing over $20!
