Well, the marketing course found at http://www.marketingtips.com/tipsltr.html is probably the best one ever written to this day. It's a bit pricey, though. Not sure if you would consider it for beginners, but it certainly is thorough, IMHO. But perhaps worth a look into if you have the cash. There's also a free one too more geared for beginners. http://www.imstarter.com/

It also does not hurt to learn from forums like this one as well as others. Problem with courses and guides is that they do not contain the latest techniques since said latest techniques might only work for a few months and then no more. But they can prove to be more profitable than the traditional techniques while they are workable. I won't list any forums here as I don't know if it's allowed, but if you do a search on Google for internet marketing forums, I'm sure you'll find a few of the best at the top.

Hope that helps.

Good luck
