If you're looking for a specific piece of information, sometimes it can get buried in a long web page. Click on the Cached link, and Google will show you the snapshot of the webpage that is stored on their server with your keywords highlighted. This can help you scan a web page quickly to determine if it's what you need. Keep in mind that this is old info, and not all websites contain a cache.
Another way to quickly drill down to the results you need in a page with a lot of information is to just use your browser's Control-F (or on a Mac Command-F) function to find a word on the page. Many people forget this is an option and end up wasting time needlessly skimming through a pile of words on a long page.
