Francois-Pierre Marcil: First, Google updating their algo daily is not really the factor that explains daily ranking fluctuations. Factors such as personalization, crawling, new content, penalties and all the others day-to-day activities necessary to maintain search engines are bigger daily influencers.Secondly, to answer your question in spirit: Sites with stable and high rankings tend to a)build sustainable value and b)build sustainable market advantages c)improve over time across everything measured by Google.
