At least a few times a month I get asked various questions about myself why a search engine ranking looks the way it does.
For example, someone might ask me how they can influence the description and/or title that Google gave their website in their search engine ranking. But easily the most prominent question is "what are those links that show up under some #1 ranking? How can I get those?"
Well, I think it is time to introduce you to a great little video featuring Google's own Matt Cutts in November 2007. The video is an excellent section by section walkthrough of what you know as a search engine ranking but Google calls a snippet. Enjoy!
