Yesterday I posted a video to YouTube about my skiing trip, and put keyword tags in there.
Well, today I searched for more info. on the resort on G and was amazed to see that my video and a friends' was featuring as Google result #1 and #2.
So this is an easy way to get #1 ranking for minimal effort for maybe unusual search terms. No website needed, just upload a video. You can add a link to your site in the description.
