Google does not disclose exactly how much you'll earn per ad that is clicked.
How Much Can You Earn With AdSense?
The commission you receive per click depends on how much advertisers are paying Google for the particular ad. You will earn a share of that amount. I've heard of earnings anywhere from 2 cents to $15 per click.
So it is logical to believe that keyword phrases like debt free, employment, make money, mp3, sex, etc. will earn you more per click since these are highly competitive keywords that are searched for quite a bit on the web.
Advertisers generally pay more for popular terms because they are searched for more.
Even though Google will not reveal how much you are earning for each ad that is clicked from your site, you can still login to your account at any time and see the total amount of revenue you've generated that day, week, month, year, etc.
For example, if you see that you've made $12.60 today from 9 clicks then you can calculate that your average click-thru commission was $1.40 per click. That's as detailed as their stats will get. Also remember, that's only an average. You won't know how much each specific ad brought in.
The amount you'll earn also depends largely on the amount of targeted traffic you receive to your own site, how well the ads match your audience's interests, the placement of the ads on your pages, and of course the amount you receive per click.
Ideally, you should create a site on a topic you know a lot about. That way you'll have a much easier time creating a generous amount of content on that subject.
My Google AdSense EarningsI have been receiving monthly checks from Google since 2003, and I've read numerous success stories of websites earning 5 digit incomes per month with AdSense.
Now, I will admit, a 5-digit commission in a single month is probably not the norm for most participants.
I promote AdSense on three of my websites and my monthly checks are usually around the $6,000 mark.
My sites have been around for a long time and I have a great deal of traffic so that's a big reason why I earn so much. I promote my sites on Twitter, YouTube, Facebook, Banks and Cricket etc. Making a lot of money with AdSense is all about numbers. The more traffic you have, the greater the earning potential.
My checks weren't always this large. I think my first month's earnings in 2003 totaled less than $20. However, as my traffic increased, so did my checks.
