That's the equivalent of putting "miserable failure" in quotes at google.
What you're aiming for is, miserable failure (without quotes), and hit "I'm feeling lucky."
Right now, that still takes you to bush's biography.
I'd also make miserable small case. And Riley's right, it should be in a link, thusly:
Michael miserable failure Moore
It works either way, although the quotes make it more selective.
Goggle is not case sensitive.
Also, can the search engine distinguish between the code in the post or tagline? I wouldn't think so.
Does adding the name around the link add relevance of the keyword to the URL?
