I have a website in Spanish football this month and 3021 page impressions and 11 clicks ... Are you okay these numbers?
You have promoted your site well and got good number of clicks. I agree with OMSHANTI. You need to do more research on high paying niche. Again you also need to work on Adsense optimization. Generally 300x250 block of Google Adsense pays well. This is also recommended by Google. I suggest that you continue to build on unique and quality content and you will get indexed by Google quickly which will result in more number of clicks.
Sports niche is craps steer clear of it I have around 4 sites that get decent impressions and clicks in adsense but they generate no cash so stay clear!
u must have english website & work hard ... I have website have 70k page impression but his income very low (Not english)
