An easy method.. yet so hard for many. The biggest issue for those having trouble, believe it or not, is yourself.
Over-complication can be the death of an otherwise great and able marketer.
Finding a decent product has been tough for me. I tend to look too much, finding a fault in all of them till there is nothing left. I was far too picky. Eventually, I just said what the hell and did one. I figured it doesn't take long to write the articles and that I'd rather error on the side of promoting a non selling product, than not promoting one that turns into a big seller.
Writing has been hard because it can't be an advertisement. It has to be similar to a review type article. That is restricting in the way you can setup your article. I am better at selling and promoting than reviews.
When I was researching a few products, I found some articles that were recently posted by people trying this method. They were for some older high gravity fitness products, and they placed very high in google. So that part of the method worked great for them.
But I have to say, and I hate to have my first post be so negative, but they were really bad. The content was meh. Nothing that would make me want to finish the first sentence, let alone click the link. I'd recommend people reading up on how to sell to people and maybe some basic advertising info. This is important, if not the most important. And not just for this method, but for all of IM. This is what we do, sell. It's central to most, if not all, techniques.
The other thing I noticed was most had bad formatting or none at all. One huge block of text that everyone would have had a hard time reading, if they even tried, that is. Split it up into easy chunks for the reader to digest.
Lastly, they had like 5 versions of the article that were ran through a spinner. The problem with spinners is most of the time you end up with words and sentences that, while technically correct, would never be used in that manner by a normal native speaker. Some words are only used at certain times or in special slang/jargon situations. You lose the context with spinners and end up sounding like a boater that just learned the language from a dictionary. Not at all pleasant to read.
If you use a spinner you NEED to proof read it after. I find I end up editing much of the spun article to make it work. With long articles, this is fine, but with such short articles, it's almost as fast to write it from scratch. You've already done the research for the article. Pumping out another article in a different format should take 5 mins to write.
After hearing that some people have posted 60+ articles with no sales, this might be why. Being fast is all good and well, but if it's not a reasonably good article, this method won't work. Concentrate on creating decent articles first, the speed will come with experience.
