What does CPC indicate?

When we think of high paying keywords, the first thing that pops up in our mind is CPC. CPC (Cost Per Click) is the maximum amount of money an advertiser is willing to pay for a click. Higher the CPC of a particular keyword, more will be the payouts you can expect by targeting that keyword in your AdSense websites. You can get the most accurate CPC from the source itself - Google.

However, CPC is not the only factor that tells the profitability of a keyword. There are many other factors that you should consider.
