How much money can you make with Google Adsense?

 Many people are curious how much money they can make from using Google Adsense. As always, the answer depends greatly on the publisher's site. The key to adsense success is traffic and CTR (click-through-rate). Websites with more traffic make more than websites with less--generally.  CTR is critical in that it determines whether you get paid in cost-per-click (CPC) or per thousand impressions (eCPM, RPM).

Why is CPC preferable? Assume you have 5,000 unique views per day, with a 2% CTR (a standard rate). If you're getting paid by CPC (roughly 20-50 cents, potentially much more), then you will make $20-$50/day. If you're CTR is low (<1%), you'll probably be paid by eCPM (roughly $1-$4/thousand impressions). Now, you won't be paid by user clicks but by page views with estimated earnings between $5-$20. For sites with minimal traffic, unless the ads are highly targeted (and have considerably high CPC) you might not want to bother.

Take a look at these two examples:
