How long have you been doing this OP? IM requires patience, so you just might need to push it more time and try various strategies, niches and etc.. The most important thing is not to give up and try different things until you find your goldmine!
that is certainly true. The thing is, your're surrounded by all these methods that people write on here that are making money and you think to yourself "damm, let's try that" and then you do that for a day or so and another method pops up and then you start again.It's a vicious cycle.
Pick one method, something you think you'll stick at, and get good at it. I know the temptation is hard to resist when things ain't working out and you want to try something else, but trust me, you'll never achieve that 5 figure month if you don't specialise in one method. By all means, once you have mastered that one method, then feel free to expand, but until then stick at it mate.
For example, I've been building this site in the weight loss niche targeting a product, something which I haven't got a clue about.3 months down the line and I've just hit #5 spot for one of the main keywords and made my first few sales. But do you know how many sites I've built before that that sucked and flopped?
FOCUS, FOCUS, FOCUS and you'll do it. Ask yourself, did you really try hard enough? if it didn't work, then maybe change the niche? or maybe change the game product? Like all industries, you can make money in anything, you just have to find your angle.
Hope that helps pal, and trust me, I know how it feels, but until you just focus on that one method and master it, you'll never make that big money.
