Widely considered a leading "search engine guru," Danny Sullivan has been helping webmasters, marketers and everyday web users understand how search engines work for 15 years.

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.

Danny currently heads up Search Engine Land, which covers search marketing and search engine news. He produces the SMX: Search Marketing Expo conference series, writes a personal blog called Daggle (and maintains his disclosures page there). He can be found on Facebook, Google + and microblogs on Twitter as @dannysullivan.
