Danny Sullivan over at Search Engine Watch also has a nice article on Google, Yahoo, and privacy concerns. Those of you who use Google on a regular basis know that the search engine uses the PageRank technology to rank the popularity of web pages. Whenever you visit a website through Google search results, you are sending information to the Google servers that is used in calculating that site’s PageRank. If you’re concerned about any potential privacy problems with this practice, read Danny’s article and rest easy.
