Google Adsense

Don’t try to compete with the experts for the $100 keyword.
It may work from time to time, but you’ll have more success
with mid-range keywords, and less competition too. By
using mid-range keywords, you are more likely to achieve
success over the long term. Remember that success in
driving targeted traffic to your site by being ranked high in
the search engines will increase your CTR with AdSense.
