I suggest you keep your google adsense. I also thought of that but maybe in years to come, once we get traffic on our website, the earning possibility is endless. Perhaps we just have to work more on SEO.

Actually, I have this friend who just started his blog a year ago. I was 2 months ahead of him yet he aced it since he focused on SEO. He's now earning $2-4 per day through adsense. Amazing isn't it? You can check out his site, ieltsdragon.com
