First of all, there is no tool available for determining the Google payout for every keyword. Google simply prohibits anyone with an account on Adsense to divulge any information pertaining to Adsense income. But don't fret, because there are other tools that can give an idea on high paying Adsense keywords, which in turn can bring in the profits.

Among the tools, Adwords seems to be the most popular keyword tool. But before using this tool, bear in mind that is important to determine how many searches were performed for a particular keyword, how many websites are after that keyword, and how potentially profitable that keyword is. As such, it is best to opt for the tool which can provide these information.

Wordtracker is the most commonly used tool in finding high paying Adsense keywords. In using this tool, one also gets keywords which are not very much up for competition to other websites. But the downside is, Wordtracker comes with subscription fee which is quite expensive.

For people who want a similar tool but is free of charge, Nichebot is one good alternative. This tool is online and runs quite slow compared to Wordtracker. Nevertheless, Nichebot has some impressive and newer features, since the tool is updated on a regular basis.

Another no-cost tool is KeyWordDiscovery. This application is known for keyword search, though it is free only for a limited period. But one may decide to pay the subscription fee should he find the service of this tool satisfactory. Otherwise, he could try Overture Keyword Research. This tool provides keyword searchers with what they need, although the overall result is derived from Overture search engines.
