Your AdSense dollars are always wisely spent when you invest in and track your highest-paying keywords. Although you may not realize it, there are hundreds of keywords that are often overlooked simply because they're so simple! The top subjects today include technology and Web-related information, health and wellness, food, dieting, movies and gossip, university degrees online, point of sale software, and even some politics. You know that driving traffic to your Website and advertising boxes itself is what will make your AdSense program work. When your customers are finally at your site, you'll want to make the most of the keywords that you've chosen!

The easiest way to assess the popularity of a particular word or subject is to run it through one of Google's or Yahoo!'s free keyword selector tools. Simply type your keyword into the box, and it will generate this month's advertising value. The first step to finding the highest-paying keywords is to run searches and track what you find.

You can choose to return results on cost, negative keywords that could have an impact on your program, and even look at global search volume trends showing which month a particular set of keywords was most popular.

Yahoo!'s Keyword Selector Tool gives you suggestions on additional keywords based on what you initially specify. This can help you create new and evolving keywords based on what you know works and what doesn't. The site is a part of Yahoo!'s Overture, and lists and ranks the keywords based on popularity. It will show you the important data you need about the number of searches done for a particular keyword or set of keywords for the current month. It's easy to compare and contrast other related searches from one simple request!
