Remember back in 2001, during the good old days (of the internet) when you could actually use Google Adwords as a means to drive quality traffic to your website, at an extremely low investment to the advertiser? Back when niche keywords cost .05 - .20 per click and if you really wanted to open up your pockets and bid on broader terms, you would pay .25 - .75 per click. Now days you would be so lucky to find a niche where you can pay under $1.00/click.
