A very important element in the rapid adoption of AdSense is that it has been very easy for publishers to get the ads on their site as quickly as possible.
Integrating AdSense in your website takes only a few minutes, and you can be on your way with one or more nicely integrated AdSense ads.
The first thing you need to do is navigate to http://www.google.com/adsense and either apply or log in with your existing account and password. What follows is a page presenting the Google AdSense Terms and Conditions which you must agree to in order to proceed.
You are presented with a report page which you can use to get a detailed status on how your AdSense advertising is doing. This allows you to improve your site's contents and layout to maximize your AdSense earnings.
On the top of your page you also have link to the setup section where you can generate the code that will need to be pasted on your website in order to have AdSense banners on your page.
You can use AdSense for text (the said ads), using a search box or with referrals. Your choice among these options depends on how users will navigate your site.
Finally, there is a "My Account" tab which allows you to set up details concerning your account, payment and tax information.
To add a text ad on your site, go back to the "AdSense Setup" tab and click the "AdSense for content" link. Make sure you have cookies enabled in your browser.
You can make a choice between ad units and link units. The former contain text and or images concerning a certain site for each unit, most with a detailed description, the latter only contain links to certain types.
Of course, it's a bit hard to know which type you should use so you should probably experiment with both for a while before you decide.
You can also view an example of how the unit will look to the right of your page. However, you may only use three ad units and one link unit on any given page. This is believed to be a step which Google takes for quality control.
