Someone once said making your first million dollars is the hard part, but once you've made your first million, making another million is easy. I'm sure that has to do with learning all the ropes on the first mil and finding what works and what doesn't then rinsing and repeating what works for the 2nd mil. I am certainly no expert on making money online, I think I've made about 3 dollars so far, however I have become well versed in the art of having too many irons in the fire. So here are my initial thoughts when I read your post.

Have I spread myself too thin?- It sure sounds like it. I know there are those here and elsewhere that have multiple sites and projects going on at any given time and are posting success nuggets from time to time, but I'm sure they have their struggles as well, those just don't always get posted as often. I'm learning quickly now after joining WA and reading and listening to others, that the only way I will ever be able to master many things is to master one thing at a time, or if the word Master is overwhelming, then let's just say to become proficient at one thing at a time. At some point it becomes second nature to do a task and at that point then you can add another task to your arsenal. The trouble is that it's too easy to want to move on to something else,because it's exciting and even energizing to learn something new. Sometime's it takes a forced focus to continue doing the same thing until it becomes second nature. To gain a strong foothold you've got to master all the steps, but you must do it one step at a time to get to the top.

Are the Niches I have chosen too competitive? Very possible they are, and/or too broad or without the right audience. Fortunately, you are in the right community to find those things out. There are those here who are willing to look at those things for you and give you their thoughts based upon their experience. Ask one thing at a time and use your results to make your corrections. Then divulge your next struggle, and so on , and so on. Master each one for your own sake and the sake of those to come who will have the same struggles to whom you will someday be able to shed some light as well.

Am I targeting the wrong Keywords? Quite possible, Jaaxy seems to make easy work of correcting that however, and again there are those here who have a vast knowledge of choosing the best KW's and have written tutorials and blog posts and are also willing to answer any questions you may have and perhaps help you pinpoint the proper process.

If I keep doing what I am doing, will the traffic come? I'm sure some traffic will come. Do you have a traffic goal for each of your sites, (as much as I can get doesn't count, we all want that) are you tracking results and seeing what works and then amping those things up. Only makes sense to do more of what works and less of what doesn't. Once again, there are those here who have a real grasp and true understanding of how to track and measure results, if you learn to do that you will be able to answer this question for yourself with great confidence. Which leads to your last question.

Am I on the right track? YES, MOST DEFINITELY, WITHOUT A DOUBT. Sometimes we get tunnel vision and it tends to blind us to the road signs assuring us we are following the right path to where we want to go. Presuming, of course, we know exactly where we want to be.

Hope this helps somehow. Unfortunately, I am not yet the master of any of the technicalities of the above, but I am on the same sojourn as you and many others here and these are just some things that are becoming more and more apparent to me.
