Earlier I posted about Rand Fiskin's list of search ranking factors and how I wished they could be rated in order of importance. As I later wrote, Rand invited some people to take a stab at doing that. Today, he's posted the revised list, as he explains more here. Below is the top ten list and average scores (5.0 would be the highest you could get, meaning it was deemed super important).

1. Title Tag - 4.57
2. Anchor Text of Links - 4.46
3. Keyword Use in Document Text - 4.38
4. Accessibility of Document - 4.31
5. Links to Document from Site-Internal Pages - 4.15
6. Primary Subject Matter of Site - 4.00
7. External Links to Linking Pages - 3.92
8. Link Popularity of Site in Topical Community - 3.77
9. Global Link Popularity of Site - 3.69
10. Keyword Spamming - 3.69
