SEO Vs. Adwords

Hi kamalmix,

There is a fairly steep learning curve to AdWords. I recommend that you get the basics down before looking at any other courses. This link is the best place to get started, in my opinion:

Go through the course training and practice exams to get a solid foundation to begin your learning. Then, before launching your first campaign, study the Adwords Policies, including Google's Webmaster Guidelines which are part of AdWords compliance requirements. Bookmark this page and visit regularly to keep up with policy changes:

Next, open an account and start with a small daily budget. Set aside a budget just to learn the ropes, with no expectation of making a profit. Once you have ran a few campaigns, and learned how to optimize those learning campaigns, try a serious effort at a profitable campaign for profit. There is a lot to learn so pace yourself and try not to get discouraged while learning. The payoff comes down the road, once you have mastered the basics and start learning intermediate and advanced strategies.
