If you're looking to monetize your blog or website by carrying advertising, you'll find that there is Google's Adsense and a dizzying array of alternatives.
Here's an overview of what's out there in the way of ad networks and services.
Pheedo is an ad network for putting ads in your RSS feed.
Some ad networks offer the option of in-text ads. These are the double-underlined words you sometimes see in a website's content. You'll want to be careful with this intrusive ad format because it can annoy your visitors. Make sure you don't do more harm than good. Likewise with ads that pop up new windows under your visitors' browsers.
The key to making the most of any kind of advertising on your site is closely tracking performance using the ad provider's tools and keeping track of traffic statistics using tools like Google Analytics.
When you start out you'll want to experiment to find the best ad formats and placements, but once you get going you'll want to avoid regularly making wholesale changes. Think of it as tuning a machine rather than rebuilding it.
Here are some useful ad network guides:

Many websites offer to send you e-mail when they update their information and most news sites offer e-mail headlines. These services save you the trouble of going to the sites, but if you have more than a few they can quickly fill your inbox.
What’s more useful is getting alerts from search engines. You can have Google, Yahoo and Microsoft’s Bing regularly send you the results of keyword searches on news and other sources.
This saves time by pushing information to you that you’d otherwise have to search for. In essence you can set up your own free content monitoring service. You can track legislation, competitors, industry trends or the goings-on in your hometown.
Google Alerts are particularly useful because you can set keyword searches for different sources: news, blogs, webpage updates, video, discussions in Google Groups, or all of the above. You could use this to, for example, set two alerts for the same keyword, one on news and the other on blogs. This would let you separately track events and what people are saying about them.
If your focus is news, you can also create custom sections in Google News. This is useful because it lets you see headlines from several alerts at once.
Make sure to set an alert for your company name.
