i want to know how to get traffics?You know more traffics could get you more clicks,then you can earn more.
That's good you could earn like more that $2 a day..There's nothing wrong with your ads placement. Just keep the updates always on your blog.
You won't be successful if you just give up. I ran a test for my latest idea over the weekend. With just 14 clicks I made $3.86. My goal is $15 a day. I stopped my paid traffic and now I am focusing on getting top page results. Right now I earn nothing a day, but I know with traffic the clicks will come. This doesn't happen over night and I would encourage you to keep at it...
