I have written an article on achieving a high eCPM. The steps I speak about are Write about high paying topics Improve ad placement (CTR) Decrease bounce rates Focus on targeted traffic Avoid being smart priced If you would like to read the entire article you can read it here - 5 steps to a high Adsense eCPM.
The faster way to a high eCPM is to have a single click on a page with a single impression (100% CTR) with a high PPC ad. For example with an ad paying $1, the eCPM would be $1000. If that single click is all you receive, your payout is only $1. It's possible to have an extremely high eCPM and be making almost no money. Knowing that you WOULD have received $1000 if every click paid $1 and your CTR remained at 100%, and you received 1000 impressions, is not very useful. eCPM is therefore not a very meaningful number in understanding how you site is doing with Adsense.
Yes we all know this, but if you want to have high eCPM with 1000+ impressions you will need to follow the 5 steps I listed.
Thanks man for your sharing, but with experience the best way to a high eCPM: Work hard and forget that you have adsense on your site. Regards.
I think that's the best way to get high traffic, but not to get high eCPM. You should build traffic through hard work but high eCPM through the 5 steps.
