Its a good Video from Matt Cutts regarding what to chase while doing your SEO. Though one may not call it as a great SEO tip but i firmly believe that if you make a good and genuine effrot to engage your visitor with usful information and a great browsing experience on your website then Google will love you too.
Thus Don’t Chase Google ; Chase what users users want . You and Google will meet at a common point (Read pos 1) soon. Most of the times SEO’s lose the track and try to fool Google / Users . It ,may help in short term but definitely a No No in the long run.
