Please review this site http://www.yousportz.com Code (markup): im getting less than 0.50% CTR for last couple of weeks
I think you don't worry. Your site is verry good. I think you should write description for video carrefully
I am new to all this, but from what i have read from google. Adsense seaches your site for info and then display ads accordingly. Because you have little text adsense is displaying ads not related to sports. therefore sport fans visiting your site are not encourage to click on them. Your placement i think is great, and your site looks really good. good luck.
