Custom Search helps users find the right page by showing them a snippet—a small sample of content that gives search users an idea of what's in the webpage. To learn more about snippets, see the Webmaster Central blog post on the anatomy of a search result. If you do not like the standard snippets created by the Custom Search algorithm, you can create your own snippets. You can showcase key information—such as image thumbnails, summaries, dates, authorship, ratings, and prices—directly in your snippets. Having the most relevant information in your search results makes the webpages in your site more compelling to your users. The following figures demonstrate various ways you can customize the snippets in your search results.
Custom Search is a fast way to generate a search function, which can be restricted to one or more websites if you choose. Both javascript and *CSS** are generated automatically. Either the graphical Control Panel tool or an XML file can be used to customize the search or it's results. It can also be integrated with Google AdSense to earn money when users search other websites.
