I added Qadabra about a week ago to my blogs Techno World and Lab World.Together,I get around 500-600 visits daily.However,average eCPM is $0.3.One day,they gave me eCPM of $23 but on other days,it ranges from $0.1 to $0.3.They claim that with time,the ads become more relevant.Has anyone worked with qadabra before?Is it legit and does the eCPM really increase with time?

I haven't yet applied for Adsense,since my blogs aren't yet 6 months old.
