My experience with article marketing (on all platforms) is that it really is much easier, much more time effective to skip the quality content and just go straight into hyping and selling? My results with delivering 'expert content' in particularly money niches, have been pretty bad.
What I'm talking about is the difference in effort, time and money between going for 'expert' in a niche and just being a smooth marketer.
I mean, once you set out to be an expert and deliver real expert content, you really have to be an expert, right? If you pass yourself of as an expert, then if you don't deliver expert advice, you're not going to get those clickthrus.
On the other hand, be a marketer, just learn the buzzwords, promise the world in 250 words and drop your hoplink. That's going to scare away some people, but it will attract those who want to feel like their worries are over. "Thank god I found this, now I can stop working tomorrow" people. Market to them with realistic and honest advice and they'll click the back button before ending the first paragraph.
I know, I'm skipping expert and going straight to hype.
