No doubt that Google Adsense has become the number one player in making money on the internet. The latest claim that I saw advertised was an internet marketer that made over $19,000 in one month. What is their secret? It is simply writing articles and building adsense webpages that use high traffic, or even some traffic, that use profitable keywords. Not just any keywords, profitable keywords. You have to find keywords that your customers use and that your competitors do not use. Their are many tools available and this article will cover just a few of them.

WordTracker is the leading keyword research tool. SEO professionals worldwide use this tool to find profitable keywords. Wordtracker's suggestions are based on over 300 million keywords and phrases that people have used over the previous 90 days. (In other words, there is no "guessing" when you use Wordtracker. Everything is based on the keywords millions of people have actually typed into search engines.)

KeywordDiscovery is also a very popular keyword research tool and is a major competitor to Wordtracker. KeywordDiscovery compiles keyword search statistics from over 180 search engines world wide, to create what they call "the most powerful keyword research tool". It has been noted in a number of reviews that Keyword Discovery returns more words that are relevant than Wordtracker, Yahoo's or Google's suggestion tools.

There are many other tools on the internet that are worth mentioning. They can be used to supplement and verify the profitable keywords that you find using the major keyword tools. They include, the Google search tool, Yahoo Overture, SEO20/20, webconfs website keyword suggestions (you put your competitor's website URL in this one to determine the profitable keywords they are using), and many more.

The SEO20/20 search tool is the most valuable for determining monthly traffic for profitable keywords by search engine. It includes information on the Overture bid prices, total monthly search volume, estimated search volume for Google, Yahoo, MSN, Digital Point (WordTracker), and Nichebot, Google trends, Google Traffic Estimator, Google Suggest, Google Sysnonyms, and Adwords Keyword Tool. It also provides you with links to news searches, directories, blog searches, tag searches, thesaurus, dictionary & encyclopedia, classifieds, products & revies, and local results for your search term. All in all, not a bad tool.

Finding profitable keywords that are often searched for will help you meet your goals of bringing more targeted traffic to your web site and reaching that top ranking that sometimes seems next to impossible. Reach these goals and your profitable keywords will equal Google Adsense Campaign income.
