Nigritude Ultramarine.

In the English-language world, the nigritude ultramarine competition created by DarkBlue.com and run by SearchGuild is widely acclaimed as the mother of all SEO contests.

Last year Mr. Dash participated in a challenge in which competitors attempted to get their Web site to be the first Google result for the made-up phrase "Nigritude Ultramarine."

In May 2004, the websites Dark Blue and SearchGuild teamed up to create what they termed the "SEO Challenge" to Google bomb the phrase "nigritude ultramarine".
