I know some keywords are worth more than others, but if I'm going to start an adsense campaign, I'd like to have some idea as to how much of the click money I get. 10%, 20%, 50%...?
Only google knows how much you will be earning as per adwords bid. They won't reveal any formula for us.
It depends on the niche of your site and the keywords u use for your sites SEO and most importantly on your CTR rate and eCPM rate--$$ from the clicks of visitors from US,Canada,UK and Australia are mostly higher
