When you join the AdSense program, you get access to AdSense for content which places ads on your content pages. Because the ads are targeted to what visitors are looking for on your blog or they match the interests of the visitors your content attracts, you earn and at the same time enhance your content pages. Google uses its vast search technology resources to serve ads based on blog content. In this regard, AdSense has become a popular choice for placing advertisements on a blog because the content of the ads is relevant to the blog. For example, ads for kitchen utensils will appear on a blog post about healthy cooking. Google has an extensive inventory of ads for all categories, business, practically for all kinds of content. If Google is unable to display targeted ads on your blog page, you can display a default ad of your choice.

A companion to the AdSense for content is the AdSense for search. It allows you to add a Google search box on your pages. This keeps the visitors on your blog longer since they can search from right on your blog. When a visitor searches the web using the search box, Google shares any ad revenue it makes from those searches with you and you shell nothing to participate.

Another recent addition is the AdSense for feeds. This runs on RSS and Atom feeds. RSS and Atom feeds are standards for publishing regular updates to blog-based content. Ads are displayed in the most suitable feed articles. You are paid for your blog's original content; visitors see appropriate advertising and more relevant feeds to choose from.

Once you are accepted, all you need is a bit of javascript code to incorporate the advertisements into the accepted blog site. Google does the rest like providing appropriate ad links from its inventory of clients to your blog. Targeted ads will start showing up on your blog.
