The Web is a very large social network. It is important and interesting to understand the “ecology” of the Web: the general relations of Web pages to their environment. The understanding of such relations has a few important applications, including Web community identification and analysis, and Web spam detection.

Then, we analyze the farms of a large number of (over 3 million) pages randomly sampled from the Web, and report some interesting findings. Most importantly, the landscapes of page farms tend to also follow the p...
