seems to me you need to focus on buying keywords - and not look at the larger ones for now - as your site is too new.
if you get yourself 10 sites and more articles / reviews you should be at $20 a day
Getting bigger than that requires more thought in terms of products / niches.
All the best.. try to remain on the safer side in all your moveI had 3 EMD sites that got hit by Google algo updates. It was real mess and I wanted to give up. However I can't give up just like that and I bought another domain. Now I'm going to create an authority review website 50+ posts with a lot of quality content. Stay tuned and I hope you'll follow me. More info you can find on page 3 of this thread.
