Google has a way of surprising the bloggers. We have been using google adsense for 10+ years and still feel this is the most reliable and successful program to make money on the internet. Recently, we got a mail dispatched to us on our doorstep, with a coupon code for Google Adwords program.
With google adwords we were able to set up our first campaign to drive targeted traffic to our blog. Here are a few offers from google adwords to get you started for free, with a little effort you can bring traffic to your blog,
Update : The offer links get outdated, however you can search for offers in google, to get an offer which is still valid.
