To an extent yes, that's why I added the second paragraph in that section. I said if you are already writing about web development (which you enjoy) you can increase your eCPM by writing about 'purchasing web hosting' rather than 'free web hosting'.
* Write about high paying topics Do you mean writing about insurances and high paying keywords? well thats bad tip since many websites are made for public not for adsense. * Improve ad placement (CTR) yep, this is tricky, needs allot of testings to see whats best placement. * Decrease bounce rates yea, yea but how? if they are set to go they are going to go. * Focus on targeted traffic very good tip, like it. * Avoid being smart priced dont understand this, please explain what this emans
*Whether you choose to write about a high paying topic or not depends on you, but your CPC will reflect the topic you choose. *Writing good content reduces bounce rates. I guess I forgot to say that. *It is a very useful tip. *If the visitors you send to the advertisers don't convert to sales you may be smart prices. Don't trick your visitors into clicking or they won't convert to sales, and you will be smart priced.
