Ask HN: Is it worthwhile it to put ads on a site (Alexa ranked #2,209,472)?

Hi HN, I created a download video website (keepandplay.com) some time ago, it is a rather simple site but with a tremendous support to multiple sites (youtube, twitter, Facebook, instagram....)

Since I created the site I didn't get any profits... no ads or similar.

Does anyone know whether it is worthwhile to put ads to earn some money? KeepAndPlay.com is ranked #2,209,472 on Alexa and produces 1,235 session per month (Google Analytics)

Suggestions on how to improve are welcome

Thanks!
