Long story short, I started trying to make money online four years ago. Since then I've made several what I thought to be good websites, to realize they never came to anything more than great learning experiences. None of the websites ever made more than $20 a month, despite hours of work every single day writing content and marketing it.
My first site was a general tech site. Niche was way too broad. Had an RPM of $5 but traffic was hard to get. Moving on, my next website was more refined, iPhone, iPad, and iOS in general. Got alright search traffic (200 visits a day) and a pagerank of 2. RPM is around $3.70 (I have no idea how good or bad this is.) Anyhow, when I realized I was working way too hard and not making enough, I lost interest. I then went on to buy an Android phone, so I'm done working with that website completely.
Anyway, fast forward another few months. I launch another website, this time in the cryptocurrency niche. Search engine traffic is well, and I'm getting up to 400-500 visits a day with very little marketing. The problem? The RPM is only $1.20 in Adsense, and there is almost zero affiliate marketing potential.
Fast forward to about a month ago. I try to launch my first non-blog website, in the insomnia niche. I write 25 or so completely unique pages on everything about insomnia and how to cure it. I leave valuable comments on over 250 articles on other websites related to insomnia. I write a very long and detailed Squidoo lens on insomnia with links pointing back to my site. I even made a YouTube channel and produced several videos to go along with the articles. This was going to be the one I thought. Nope. It's getting around 15 views a day, zero of which have come from search engines. Heck, GWT has only even updated twice in the past 20 days (I assume that means no impressions at all?)
I just simply can not figure out what I'm doing wrong. I'm willing to put in the time and effort, and I have. It's just so discouraging when I put hundreds of hours into a website, and a silly YouTube video I made one one Sunday afternoon is making more than all of my websites combined.
I'm at my breaking point. Any input or advice would be much appreciated.
