The value of a keyword will always vary greatly and there are way too many factors to come up with a 100% accurate formula. Still, I wanted to share a formula that I learned as newb on how to estimate how much you can earn with any keyword via Adsense. (Some of you might recognize this.) Keep in mind that this only for estimation purposes to see if a keyword will be worth your while. (Exact Monthly Searches * 0.4 * 0.05) * (CPC * 0.68) = Keyword's Monthly Earning So if you are looking at a keyword with 5000 exact searches and a $1 CPC, you could expect to make: (5000*0.4*0.05)*(1*0.68)=$68/month For many people, they get to #1 in Google and wonder why they are not making enough money to quit their job and buy a new house. It is either because there is not enough traffic or because that traffic is not very profitable or both. This formula makes a few assumptions: 1) It assumes that the keyword tool you used to do research is giving accurate data about traffic and CPC. 2) It assumes that when you reach #1 in Google that 40% of all searchers will click on your site. This is the 0.4 in the equation. 3) It assumes that 5% of those who click on your site will click on your ads giving you a 5% CTR. This is the 0.05 in the equation. 4) It assumes that Google will give you 68% of the click payment since Google says that this is what they will do. That is the 0.68 in the equation. There is a lot of room for variance in all of these assumptions which is why it should be used for estimation purposes only but I found it very useful when I was starting out and I thought others might as well.
