The father of SEO is Bruce Clay, the person the industry most often gives that name. He started Bruce Clay, Inc. in January 1996, built early SEO tools and trained more than 5,000 people, and he died in late May 2026. He is widely credited with coining the term search engine optimization, though no one has proved who used it first.

Bruce Clay tells his story in his own words in this long interview from Shelley Walsh's SEO Pioneers series, from his years as a programmer to how he came into the industry.
Bruce Clay is widely credited with coining the term SEO, but the record doesn't prove it, and he said so himself. In his last interview he told Search Engine Land that he had been given the credit, and then that "nobody knows who was the first to ever say anything". Danny Sullivan, who recorded the early industry, found no definitive first use and named Clay as one of the first to popularize the phrase.
Popularized became coined through repetition. Clay's own company timeline has him starting to use the phrase in 1997, the same year as everyone else, and later tributes rounded that up to first. The earliest dated public use is a sales pitch on Usenet in July 1997.
Who else claims the term SEO is a short and contested list. Rob Garner, writing in Search Engine Land, says five people reached the word independently between about 1995 and 1997, which may be the fairest ending this story gets.
| Who | The claim | The evidence |
|---|---|---|
| Bob Heyman and Leland Harden | Summer 1995, after a late call about the Jefferson Starship site | First in print in the 1997 book Net Results |
| John Audette | Early 1997, at Multimedia Marketing Group | His own account, and he knows it is disputed |
| Bruce Clay | Company pages say 1996 and 1997 | He said nobody knows who was first |
| Danny Sullivan | None | He says he didn't coin it |
| Jason Gambert | Tried to trademark SEO in 2007 | Terminated in 2010, and nobody credits him |
Bruce Clay actually did plenty, whoever said the word first. He came from math and programming in Silicon Valley, started one of the first SEO companies from home, and dated his first diagnostic tools to 1996. He spoke at the first Search Engine Strategies conference in 1999, published a Search Engine Relationship Chart and an early SEO code of ethics around 2000, and developed siloing, a way of organizing a site by subject, in 2002. His book, Search Engine Optimization All-in-One For Dummies, first came out in 2009, and he received a History of SEO Lifetime Achievement Award in 2013.
His last word on AI is worth keeping. In that final interview he called GEO and AIO extensions of SEO, as link work is, and said anyone selling AI optimization without SEO is either doing SEO or doesn't know what they are doing. That is close to where this site lands on whether SEO is dead or evolving.
Danny Sullivan is not the father of SEO, and he would be the first to tell you. He says he didn't coin the term, and he was the journalist who wrote the industry down. He published The Webmaster's Guide to Search Engines in April 1996, relaunched it as Search Engine Watch in July 1997, and created the Search Engine Strategies conference. In September 2001 he suggested search engine marketing as the wider term, and said others had likely used it first. He launched Search Engine Land in 2006 and joined Google as its public liaison for Search in October 2017. He left that role on August 1, 2025, and moved to other Search work.
No one person founded SEO, which grew out of webmasters and a handful of early practitioners in the mid-1990s, once search engines sent enough people to be worth chasing. The name most often given is Clay's, with Audette, Heyman and Harden beside him and Sullivan recording it all. The early years moved quickly, and most of what follows happened before Google was a company.
| When | What happened |
|---|---|
| Mid-1990s | Webmasters begin optimizing sites for search engines |
| December 1995 | AltaVista launches |
| January 1996 | Bruce Clay, Inc. starts |
| April 17, 1996 | Danny Sullivan publishes his webmaster's guide |
| July 1997 | Earliest dated public use of the phrase, and Search Engine Watch relaunches |
| 1998 | Larry Page and Sergey Brin publish the PageRank paper and found Google |
| November 18, 1999 | First Search Engine Strategies conference, in San Francisco |
| 2002 | Bruce Clay develops siloing |
The full name of SEO is search engine optimization, the work of helping search engines understand a site and helping people find it. Google opens its own SEO Starter Guide with the same expansion, and the videos on this site start from there.
Bruce Clay died in late May 2026, and his company announced it on June 26. Some tribute pages give June 26 as the date of his death, which is the date of the announcement. His company has not published an exact date, and his age and the cause have not been confirmed, so this page leaves them out. Bruce Clay, Inc. says its teams will carry on his work.
