Widely considered a leading “search engine guru,” Danny Sullivan has been helping webmasters, marketers and everyday web users understand how search engines work for over a decade.

Danny’s expertise about search engines is often sought by the media, and he has been quoted in places like The Wall St. Journal, USA Today, The Los Angeles Times, Forbes, The New Yorker and Newsweek and ABC’s Nightline.

Danny began covering search engines in late 1995, when he undertook a study of how they indexed web pages. The results were published online as “A Webmaster’s Guide To Search Engines,” a pioneering effort to answer the many questions site designers and Internet publicists had about search engines.

The positive reaction from both marketers and general search engine users caused Danny to expand the guide into Search Engine Watch, where he served as editor-in-chief through November 2006. Now he heads up Search Engine Land as editor-in-chief, taking it into the next generation of search coverage. Danny also serves as Third Door Media’s chief content officer.
