Spiders are fickle; humans are not. Well, when it comes website preferences that is.
Search engines frequently shift or tweak their algorithms in order to offer more relevant results for their clients — human beings. While most of search engine optimization efforts cater to search engine spiders through attention to various types of links, site structure, IP address characteristics, and the like, focusing on their web surfers instead will allow any optimization effort to weather any shift or tweak well.
Granted, human on-line preferences do evolve, but they always demand quality content, attractive and clean design, logical navigation, and a superb user experience. Besides search engines are moving towards tracking user behavior as an integral part of their ranking schemes; thus, fine tuning a site with more consideration to homo sapien tastes rather than to digital arachnid druthers makes sense in the long run.
