If you write a good article about one of your sites and submit to eZinearticles you will receive more then 3 uniques a day. SEOing the hell out of those sites on-site is great but we all need to work our a.s out for off-site as well. I am not concluding that you haven't done enough off-site work but 3 uniques is showing that you definitely need to learn or implement a lot more. Don't take me wrong, I know you are frustrated and all, I just think you should work really hard off-site, here is how I break down: 60% time off-site 40% time on-site And I easily get over 200 uniques a day on two of my sites which are less then a year old.
I would suggest take a break for a week without thinking on your internet business or anything. Then after a week with fresh mind come to this online stuff and think what is it that you can do better in internet. Creating a website is easy but without interest in that website, you will worn out quickly. On the other hand, if you have a passion for something then create a website for this and in long run this will keep you and your site better
I decided to work on the porn most of the time.... But I have like 500GB of porn. I have no frustration in that sence
What is your main hobby/interest. Just write about something you will learn about while administering a site. "2 birds with 1 stone". You will earn money while actually learning. This way you will never lose motivation and gain in the long-run. Anyway, I would recommend you get at least a part-time job. Admnistering a site is tough. In the beginning it is not worth the time and effort.
I think you tried to go the easy way with XRumer, but that way does not exist. This submitter needs smarter approach and a bit of time to learn to use it effectively. And I agree with the opinion that 15 sites are too many to start with. Go one by one. When one website is making profit, move on to another one.
