Bidding & CPC

Bidding Quality
It is important to see the pattern in which people are bidding on a keyword. Suppose there are 400 advertisers bidding on a keyword. The top 20 of these are paying something like $ 15 per click, while the rest of them pay somewhere between $2 and $0.05. Now you might have found some decent tools that give you the average of top 3 or top 5 positions which is good, but not good enough. The point is that akthough the top 20 advertisers are paying higher, but the rest 380 advertisers are paying quite low. There is a high probability of your getting the ads of those 380 sponsors.

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 website. You can get the most accurate CPC from the source itself - Google.
