To make a long story short - On/Off page SEO Here's a good link - http://www.vaughns-1-pagers.com/internet/google-ranking-factors.htm
Do you mean page rank or serp? serp's will change often my sites go up or down a couple of positions almost daily. As far as Page Rank goes, well... you know how ominous google is about letting anyone know what exactly improves or drops your PR.. Although Black Hat SEO will drop your PR quickly if they catch you doing it. (so i hear)

What do you mean? You've lose your ranking? It depends on many factors. It may occur for the change of search engine algorithm.
You have to cover all bases. Every time GOOGLE comes out with to update, factors that were important before become less important and Vice-Versa..
if new players come into the market and they also have done seo these factors are taken into consideration. moreover, new algorithm factrors could also play a role
What is worse - sometimes you don't even know what you have done and the rankings go down - you don't do a black hat seo but Google suddenly doesn't like your website....it can be really frustrating..
