Pay Per Click AdvertisingThere are pro's & con's to both Pay-Per-Click advertising and optimizing for natural search engine traffic.
PPC advertising has many great benefits. First of all, you get your traffic going quickly. I have used this advantage many times. I test new products and even new websites through PPC advertising before making a decision to promote or scrap my new website or product idea.
I am a firm believer in testing new products before throwing large amounts of money into advertising. PPC advertising is a great way to do this. For example, with Google's Adwords program, you can post your ad, pay a $5 sign-up fee and have highly targeted traffic to your website within an hour. How is that for efficiency?
