Having recently created a new website (DreamWeaver is amazing) whose traffic ultimately drives money into my pocket I've been researching ways for search engine placement optimization (SEO). Obviously each engine has it's own algorithms for determining relevancy to searches but there are common practices on ensuring high placement that should be followed.

Google publishes it's indexer guidelines, and third-party sites such as Scribbling.net has a cheat sheet on how to improve placement. For example, "Place more important content higher in the markup than less important content in a page."
