How to improve eCPM. Right now i have CTR and eCPM as below: Page CTR = 5.04% Page eCPM = 5.33 Is it good?
Its good and your CTR is great. You can improve your CPM by picking the right keywords with a higher value.
In some countries, the eCPM is usually quite a bit lower, so yes, that is a great eCPM. You could also increase your earnings the other way - by increasing traffic
The CTR is pretty good, and the eCPM is bad but not that much bad, many niches have lower than this, i would tell you to try for high paying keyword in your niche..
eCPM seems fairly low but it depends on your niche and country. I'm for example running a site in a country wealthier than the US and get an eCPM of ~$60 with a similar CTR as you.
ecpm is determined by country traffic you are getting to your site + keyword quality , those sites which get english countries traffic get ecpm very high
Its hard to compare as every site, traffic source and niche is different. However, what you have is above average, but in some niches it could be below average. You can see how your eCPM changes here: http://forums.digitalpoint.com/showthread.php?t=1969885
