Has been request for an italian site a SEO report that need to be executed in these days: the topic released will not contain all particulars, but i hope it will be very interesting and useful anyway as seo reference at a glance.
It will be released under this w3it.org section (italian): seo.
Commenting this thread instead, will be added time by time interesting content, all in english about seo hints. Please add in answer here any useful resource if any you know.
