Ryan Caldwell runs through a list of 10 quality indicators for a Web site, from listing a physical address on the Web site, to optimizing internal linking.
In fact, Caldwell believes you can never have enough quality indicators. He took a philosophical approach to reach this conclusion. It started with a tweet to Twitter followers, and ended in a rant philosophizing about when gains of sand stacked in a pile become a heap. The point isn't so much about how many grains of sand make a pile as, what does it take to build an excellent SEO strategy.
