If you're not familiar with (r)AdSense, it's where (r)Google pays website owners ("publishers") to run ads on their sites. Google accepts paid ads from advertisers, and then shares this revenue with the publishers who allow these ads to be displayed on their sites. They pay based upon clicks generated from the publishers' sites.

Many publishers have discovered that running Google AdSense ads is more lucrative and less trouble, than marketing their own products or services. So an entire industry has sprang up around monetizing websites using AdSense and other pay-per-click programs.

The "industry" is mature enough that seminars are even held that teach how to best monetize your content sites. I'll be attending a seminar, in New Orleans, Louisiana, on September 9th - 11th, 2005, that has this very focus. You can read more about it at: http://WillieCrawford.com/new-orleans-seminar.html

Since MOST people I've communicated with aren't earning four or five-figure incomes per month, let's examine how you increase your chances of earning these amounts.

First of all, your website has to be on a topic (a niche) where people are spending lots of money. There are niches where advertisers often spend $40 - $50 per click... just to get visitors to their websites. Obviously, these visitors buy "things" on these websites that make it worthwhile to pay that much for the traffic.

In case you're wondering what keywords any "sane" marketer would spend $50 on a single click for, read on...

Certain visitors to websites, that later convert to customers, could literally be worth thousands, even millions, to marketers. These marketers know the lifetime value of their visitors, and have the conversion rates calculated! Markets where customers can be this lucrative include legal/lawsuits, medical, higher education, real estate, new and used vehicles, investments, travel, and products offering residual income. There are many others.

I actually have a list of over 9000 keywords that I consult when building a new site, or optimizing an existing site. Doesn't it make perfect sense to create sites that attract visitors with a high value-per-visitor?

The keywords on the list above range from 93 cents to $108 per click. There ARE higher priced keywords but you probably don't want to focus on them since the competition can be incredibly cutthroat. There are niches where your competitors will actually sabotage your efforts. Money does that to some people :-)

it makes economic sense to build a site around topics where people are actually spending money already.

It makes sense to target a market where people have money to spend - and they expect to spend it on products similar to yours. In that sense, you can even set up site designed to generate traffic for governmental agencies, foundations, charities, etc. It's all about getting in front of the traffic and then re-directing that traffic to those willing to pay for it.

When setting up content sites, it's important that you not violate the terms-of-service at the pay-per-click management firm that you plan on using. For example, Google actually tells you that you should not build sites just for their Ad Sense program. Yet, they need sites to display their customers' ads in order for their program to work.

It's a delicate balancing act. Google wants to deliver relevant clicks to their customers. They know that traffic coming from "junky" or "spam my" sites may not convert as well for their customers. This would lower their customers ROI, and lead to many unhappy customers. This would drive Google's customers to their ever-growing competitors.

Google wants webmasters that have quality, targeted traffic to run Ad Sense Ads. When you set up a free blog on Google's Blogger.com they even have the AdSense invitation "programmed" into the signup process.

So how DO you win the Google AdSense War and get your share of that multi-billion dollar advertisers' revenue stream? You build high-quality content sites that focus on niches where people are spending money. It's as simple as that. You let those already doing it teach you what works best - it's a easy as that!
