You can find anything you want on the internet, including online putting lessons. These can be putting tips on a web page, putting videos on you tube, or an ebook. You can find them through search engines, advertisements, blogs, or even articles just like this one.
The great thing about the internet is that you get a look into the minds of people very similar to yourself. In many cases, they are more qualified to help you than professionals. And I am not talking just about golf, it is true for any other subject.
What good would it do for you to dissect Tiger Woods’ putting stroke and try to duplicate it? Probably none at all. And it is no different for any other tour player. It's not so much that they can't teach, but they can't relate to the student.
On the internet, you find tips from amateurs and professionals alike. The best online putting lesson I ever had was an ebook written by an amateur. I can assure you no professional would ever teach it, but it works near miracles.
The moral of the story is that it doesn't matter where your online putting instruction comes from. What matters is whether or not it helps you putt better when the chips are down.
Putting should really be a simple game. Any online putting lesson that makes putting easier for you is a good one, regardless of the source. A good and productive lesson from an amateur will always be better than an unproductive putting lesson from a professional.
