how you done it.
what's key of the ranking?
Your web have high PR, attractive contents, but with repeating the keywords not as many as other's.

The key of the ranking is backlinks with the words "Nigritude Ultramarine" from other people helping out. It is not too important how I treat these words on my page, e.g. if I repeat them endlessly, stuff them in headings, and so on. What matters is quality backlinks from a variety of places. And I guess I could say what matters is also content, because if nobody would care for the content I offer, nobody would take the time to link!

Thanx for your reply.
