eCPM issues. Please help

I am a bit worried about my adsense earnings recently..

I used to earn around 10$ a day on an average.. But in the last 2 weeks.. the eCPM has crashed. It used to be between $1 - $2.. But in the last 2 weeks its around $0.5 - $0.6

Yesterday the earning was good with a $1.xx eCPM.. today crashed again..

What can i do? One of my friend with same niche is earning much more than me with almost the same traffic and clicks..

 

Maybe your friend have use filter feafure.
you can use it to filter low prices ads and MFA site as well.

 

yes i was had some problem but after i used a filter my cPm back to normal.

 

Have you seen the thread about eCPM and how to increase it by removing the pub-id for a few days? I have two posts aobut it, on my blog as well (se signature). I have not tried it, yet, but it seems to work for some of the guys in here..

 

So we must need to filter low prices ads so we could earned much better in adsense?. Actually I am bit new to adsense and I wonder if how to increased eCPM?

 

I am worst :
