Google AdSense is the current leader in content-sensitive web-based marketing. By placing Google AdSense JavaScript code on their web pages webmasters allow Google's AdSense servers to show advertisements (Google Adwords) based upon the content of the web page. You can find some suggestions on optimizing ad layouts here. An unofficial list of high paying keywords is here. The left hand side of this page shows an example of a Clicksor skyscraper displaying a text or image ad.
Google's terms and conditions are such that some web publishers cannot use adsense adverts on their sites. Either they are not accepted into the Google AdSense program, or in a situation that is becoming increasingly more common do not wish to do business with Google. Has your adsense account been disabled? Then try these alternatives.
For those web publishers, there are many alternatives to Google AdSense a number of which are described below. If you are an advertiser then here is a list of the top 10 alternatives to adwords.
A number of publishers also find that Google does not have a wide enough selection of adverts that match the content of their site thus Google often displays public service ads (PSA) for which the CPC rate is zero. An alternative to PSAs is to specify an alternetive ad house whose adverts are displayed when Google would normally show a PSA. This increases the overall revenue your site can generate. You do this by specifying the keyword google_alternate_ad_url in the adsense java script and then direct it to your alternative ad provider.

AdBrite (Recommended by this Site)
AdBrite, is currently one of the best alternatives there are to Google's adsense, they do not offer quite as many ad formats as Google but they offer the most commonly used ones and also offer inline page links with have some great click through ratios as well as interstitial full page ads which offer an excellent way to monetize all traffic to your site not just traffic that clicks on your ads. They also have some of the best payouts outside of Adsense. They have more relaxed terms and conditions than Adsense and are much more accepting of smaller publishers including bloggers.
If you're a publisher, use AdBrite to set your own ad rates, and approve or reject every ad that's purchased for your site. AdBrite enables you to instantly sell ads to your visitors via a "Your Ad Here" link, in addition to selling through AdBrite's marketplace and sales team.
AdBrite's revenue split is 75/25 in your favor. Through a small snippet of HTML placed on your site, they handle serving, scheduling, billing, customer service, and sales. About half of AdBrite's sales are generated from their marketplace and sales team, while the other half are generated from users clicking "Your Ad Here" on their publisher's sites.
While AdBrite can provide publishers with more revenue and better ads than traditional ad networks such as Google AdSense, they work fine along-side them as a simple way to generate additional ad revenue by selling ads directly to your visitors -- something the other ad systems don't do. AdBrite also allows you to set a minimum pricing below which they will show an alternative ad networks ads. I.e. you could have say AdBrite as your primary advertiser and say Clicksor as a backup so maximizing the monetization of your website.
If you're using AdBrite in addition to another ad network, you can turn off AdBrite's "run-of-network ads" and AdBrite will only display ads that have been approved by you. If you have no ads running, AdBrite will display nothing but "Your Ad Here", so no real estate is wasted and you have nothing to lose.
AdBrite doesn't display the big "brick" of ads that you're used to. Rather, AdBrite gives publishers full control over the look and feel of their ads so AdBrite can be integrated seamlessly into any website.
Note, in my experience once you signup with AdBrite and put their code on your website it can take a day or two for their advertizing engine to kick in. So if you see the message "Advertize on this site" just be patient and give it a day or so and you should start seeing relevant ads showing up.
AdBrite also accepts Blogs as partners so if you keep getting rejected by other programs whose terms and conditions do not allow Blogs then try AdBrite.

AdToll
AdToll pays on a CPC basis. Their user interface is great and navigating through the user panel is both easy and pleasant. Payments are available via Cheque, Paypal, ePassporte and Wire/Bank Transfer. It is also possible to use the revenue you earn as a publisher to advertise your website further. Such integration is something that is entirely missing from Google's adsense-adwords.
The newest technology by AdToll is a Peel Away Ad technology that shows a peel on the top right hand side of a web site. When the mouse moves over the peel it opens smoothly to reveal the advert within. This new ad format allows you to make use of the lesser used, yet highly visible top corners of web sites. It is very non intrusive to the site visitor. Since it uses a small amount of space, it is efficient use of web site real estate. An additional plus is that such a new advertising format always draws curious clicks for visitors.

Chitika (Recommended by this Site)
Chitika - The Leader in Impulse Merchandising
Chitika (pronounced CHIH-tih-ka) was founded in 2003 and is the industry's leading impulse merchandising company. Chitika was founded in May 2003 and is based in Massachusetts. Chitika (pronounced CHIH-tih-ka) helps web publishers generate revenue using innovative publisher-side advertising and merchandising solutions and services.
Chitika began, not as a stand alone advertising solution but instead as way to compliment existing advertising / publishing programs through the use of additional Ad Units which were altogether different from the standard ad boxes, pop-unders etc that everybody else provided. Instead of displaying these 'industry standard' advert boxes with text and image ads that all look the same Chitika instead provided active boxes that showed targeted products from different manufacturers. If you ran a blog for example and discussed a product you might have found the Chitika box showing links for this product and competitors products. If people purchased these products you would get paid a commission. This was referred to as impulse marketing in the form of Premium Ad Units (eMinimalls).
Chitika has now progressed, however, into a fully fledged advertizer service. The eMinimalls initially evolved into advertizing units that would show adverts based on what people searched for to get to your site. This is subtly different from the standard keyword driven advertising since it shows ads that are more relevant to the original intent of your visitors search. This greatly increases the chance that someone will click on an ad. This type of advertising is still offered by Chitika and is a good addition to a site containing traditional banner ads. For example you could use it to compliment another advertizers service. E.g. you could show Clicksor context sensitive ads on your site and then compliment these with Chitika's search traffic oriented ads.
However, Chitika now goes beyond this, also offering what are termed premium ads. Chitika uses it custom "Click Prediction" technology to show select ads when there is a greater chance they will be clicked on. This is obviously a great way to improve your revenue.
For advertisers and media buyers, Chitika is a proven channel for targeting on-line consumers and qualified buyers. For all publishers, Chitika is an easy-to-use platform for earning daily ad revenue. If you visit a site showing Chitika's ads from a search engine then the Chitika premium ad unit kicks in showing you ads that are specific to your searching - otherwise you can have it show an alternative ad provider, such as adsense, or you can just have it collapse away to show nothing.
Chitika's search based advert units allow you to display targeted products based on what people searched for to get to your page and you get paid for clicks. Chitika offers payment by PayPal (with a $10 minimum) or via Check (with a $50 minimum).
Claxon
Claxon Media offers you multiple ad formats, accurate stats, timely payments (check, wire, & Paypal), low minimum earning requirements, high fill rates, and the ability to preview ads, opt out of ads, and set up defaults. We also guarantee speedy replies to your questions and the best customer service possible.
Clicksor (Recommended by this site)
Clicksor will pay you up to 70% of the advertising clicks revenues generated from your website. Contextual Advertising Technology by Clicksor allows your visitors to enjoy the content of your website and bring generous earnings to you at the same time.
Clicksor also has support for displaying alternatives to Google's public service ads via the google_alternate_ad_url tag. Thus you can sign up to use Clicksor as an addition to your Google Adsesne campaign.
As an affiliate, Clicksor passes its profits along to you by paying up to 70% of the advertising clicks revenues generated from your website. Clicksor provides online real time stats and a fortnightly payment schedule. In any pay period in which your earnings exceed $50.00 ($20.00 with PayPal), payments are made either by check or instantly through PayPal ($20.00 minimum for PayPal). Revenue totaling less that $50 (PP $20) will rolled into the following period.
Clicksor features:
Top pay-per-click listings (can be better than Google in some cases) from tens of thousands of advertisers.
Multiple formats available including text, image and animated ads.
Text Links
Image Ads
Flash Ads
Animation Ads
Banners
Interstitial Ads (NEW)
Pop unders
Dynamic (DHTML) highlighting
Clicksor is recommended here for a number of reasons. It tends to have a much better payout per click than most of the other alternatives and also has a bigger range of advertisers. If you provide a PayPal account they will pay you whenever your earnings exceed just $20. This means if you have a small site you will get paid much more frequently than with a lot of other adsense alternatives that have either 50 or 100 dollar minimums. Clicksor also does not require a social security number to join. This means that it is easy for non US Citizens to join and start earning revenue. Clicksor regularly shows eye catching image ads and also supports feeds from other advertisers so a single account gets you access to ads from many different providers.
Clicksor offers webmasters the opportunity to earn additional income by simply underlining a selection of clickable text or displaying targeted contextual banner on their websites.

Increase inventory
ContextAd creates keyword and category inventory across content, solving an inventory shortage that exists on search keywords.
Create new revenue streams
ContextAd offers you the ability to create new revenue streams by adding contextual ad units on your site. ContextAd uses a revenue ranking system that rewards the best performing ads with more volume. This means that the targeted ads that are rotated across your Web site are optimized based on relevance, performance, and price, so they produce as much revenue as possible. When ads are more relevant, more users will be interested in them and will click on them more often - earning more money for you.
Add value to existing inventory
Our technology identifies the most accurate keywords to describe the content on each page and then delivers ads from the related category, creating greater value. Ultimately your Web site becomes a more trusted resource for customers since they only view ads that are relevant to their own interests.
ContextAd can support customized ad units
ContextAd not only supports standard IAB sizes, but also allows non-standard sizes as well. For example, ContextWeb's PowerAd (500x300) has been created to maximize the publisher's CPM.
Customize the look and feel of the ads on your web page
You now have the ability to control the various colors of the creative units on your web pages. Customize your ads by text color, title color, background color and the border color. This can all be easily accomplished through the online portal for publishers.
Online reports are continually updated. Access them online 24/7.

Enhance Interactive
Enhance Interactive serves its customers' paid listings and contextual advertisements on search engines and content-based Web sites throughout the Internet. We partner with industry leaders such as MSN and InfoSpace, as well as smaller search engines and targeted content sites, and we pay them cash for displaying our advertisers' messages.
Here's how we work with our distribution partners:
Cobrand Search
A revenue building strategy for customers who are currently leaving your Web site. Instead of losing your users to a search engine when they opt to search the Web, simply offer them an opportunity to search right from your Web site, while you make money each time a user clicks on a paid search listing.
Paid Listings
Integrate Enhance Interactive listings with your existing search results listings, and earn money each time a user clicks on an Enhance Interactive paid listing.
Contextual Advertising
Include branded listings located throughout your site. TopLinks? pulls the most popular Enhance Interactive advertisers (based on the content of each page) and displays them in an advertisement form. Whether you need pop-ups, pop unders, sidebars, skyscrapers or banners, or button/text links, this TopLinks? program caters to you.

Exit Junction
Exit Junction is a relatively new affiliate program and, I believe, is a spin off from the now defunct Revenue Pilot. However, while Revenue Pilot stopped running Exit Junction is going from strength to strength. Exit Junction's approach is to offer a unique way of capturing revenue from exit traffic. Their approach is compatible with all the other Ad Networks included Google Adsense. The key aspect of Exit junction is the way they focus on exit traffic. This is the practice of showing ads to users as they leave your site rather than as they arrive or as they browse. This offers you an additional way to monetize your traffic and also capture ad revenue from those that stumble upon your site from a search engine and then immediately leave.
By adding a small piece of Exit Junction code to the header section of your site users are shown an advert as they hit the back button. For example, if a user came to your site from a Google search, and then immediately hit the back button to return to that search, they would be shown an Exit Junction Ad in between your page and the Google search and you get paid for this impression. The ad is directly targeted to the search term that brought the visitor to your site in the first place. Hence Exit Junction is an ideal way of complimenting your existing ad services and so increasing your sites revenue without having to switch from your current ad provider.
Exit junction also covers all countries. You get paid for all traffic exiting you site regardless of its origin.
They offer fee free payout via Check or PayPal with earnings of as little as $25 on a monthly basis.
