4 Key Factors to determine search engine relevance. There was a great post on SEOMoz that I wanted to make sure I could share. It really helps break down the sometimes complex theories of the algorithms of the search engines into 4 simple rules. This post was done by Randfish and I definitely encourage everyone to take some time to review the post. Here is a breakdown of his 4 key factors:

1. Keyword Usage and Content Relevance - He breaks this rule down from the obsolete idea of keyword stuffing to ideas that relate to latent semantic indexing.
2. Raw link Juice - Here you get to understand how high powered sites linking to you has a dramatic effect.
3. Anchor Text Weight - Learn how the keywords that link to you affect how your page is found.
4. Domain Authority - In a nutshell, how long term domains that have been trusted can impact the success of your website.

Take some time to review his post for some wonderful imagery and a great set of detailed explanations on each item.
