Different keywords pay different amounts. Other things being equal a website based around debt consolidation will generate more revenue per Adsense click than a website based around football cards. This is why an industry built around selling high paying keyword lists to Adsense publishers has become so profitable.

But it’s more complicated than this as different keywords in different niche markets also pay different amounts. If your website is not targeting the “right” (as in profitable) keywords you will probably be earning less money per Adsense click than you should be.

For example – if you increase your average CPC (cost per click) from $0.20 to $0.30 you will increase your revenue by 33%. There are two ways of doing this on your already existing website and the best tool for doing the research is Keyword Country.

1. Better target your existing webpages:

Which words are you using in your Title Tag, Meta Tags, H1 - H3 Header Tags and inside the body of your content? Google's content matching technology generates ads related to the meaning of the words on your page. If the high paying keywords for that page topic aren't in those 4 hotspots I just listed the quality (relevancy) and CPC of your ads will be lower than if they were. Google wants to match their advertiser ads to the pages which are going to offer the greatest return otherwise their whole system collapses.

This means that you want to make sure the high paying keywords are included in your hot spots. If I use UnderstandingAdsense.com as an example I logged into Keyword Country with the intention of finding the highest paying keywords for the Adsense market. I typed in Adsense and was presented with a list. "Making Money With Adsense" has the highest average CPC of $0.73 so when I've finished building the site I will optimize the home page and several other pages for that keyword so as to generate the most relevant and high paying ads possible. I will do this by including that keyword phrase (and related ones like "make money with Adsense") into the four places listed above.

2. Add additional content to your website which targets related high paying keywords:

The most important word here is related. Don’t add content pages about Viagra to your website which is themed around motorcycles just because the average CPC for Viagra is very high. Instead do one of these two things:

1. Type your primary keyword, in this example, "motorcycle" into Keyword Country, wait for the results to appear and then click on CPC. This will arrange all the related keywords by their CPC value bringing the most profitable to the top. I did this and found that -

“Motorcycle Insurance In Michigan” has an average CPC of $10.25
“Motorcycle Insurance” has an average CPC of $4.28
“Motorcycle Loan” has an average CPC of $3.34

These are very high average CPCs for which you could develop new content. These content pages would generate higher cost per click Adsense ads from your visitors.

2. Your second option is to type in keywords which are related to your principal topic. Continuing with the motorcycle theme you could type in Harley-Davidson a popular manufacturer of motorcycles. The results show that “Harley Davidson Boots” has an average CPC of $0.84. You could build a page today pre-selling Harley Davidson Boots and generate a nice Adsense stream from that page. Another extension would be the keyword “chopper”, a popular type of motorcycle enhanced by the big shows of the last few years. On Keyword Country a search for chopper brings up related keywords like West Coast Choppers, a famous chopper builder which has an average CPC of $0.95 – again a page or several pages around this topic would be a nice addition to a motorcycle based website.

Whatever your topic, virtually every website can incorporate new high paying content. So before you try and build a website in a new niche check that the website(s) that you’ve already put the groundwork into (link building and seo) can’t be better optimized for higher paying keywords and / or have additional high adsense paying content added to it. There will be at least five new pages of content that you could add to your existing website today that would create higher paying average clicks than what you are already generating.

The large majority of Adsense Publishers are still not taking advantage of these tools and are still working in the dark so to speak - unsystematically adding content, optimizing their pages and building new niche websites with no fore-knowledge of the value of a particular topic nor its potential profitability. I guarantee that if you test Keyword County for just a day you won’t want to unsubscribe - it makes our job of making money with Adsense that much easier.

They also have a free “sneak peak” tool whereby you enter your target keywords and it will give you the most high paying keywords related to that phrase. If you follow this link and click on the “try now” button in the top right you can test the three different parts of the application yourself.
