The Auction: GoTo.com and the Price of a Click

February 21, 1998. Monterey, California. Bill Gross takes the TED8 stage and describes a search engine where advertisers openly bid for placement against a keyword and pay only when somebody clicks, and the room turns on him. Gross says the audience booed. Jeffrey Brewer, his co-founder and GoTo’s chief executive, remembered the objection cleanly: search should be egalitarian and fair, and letting people buy their way in was simply wrong.

TED still teaches the incident, apparently, minus the name. The rule they hand new speakers now is don’t sell from the stage.

What he actually put on the table

GoTo.com spun out of Idealab in Pasadena and launched that same month. Bids started at one cent. Results ranked highest bid first. Gross didn’t build a crawler, he licensed Inktomi’s engine and bolted the marketplace on top, which tells you where he thought the hard problem lived. The bid price sat printed next to every result, in the open, because the transparency was the argument.

His reasoning ran backward from the Yellow Pages, where a bigger ad costs more, and forward into something stranger. Money keeps bidding honest. An advertiser who bids high on a word that doesn’t convert goes broke buying the wrong word, so the system corrects itself without an editor, a review process, or an algorithm making judgments about relevance. Relevance as an economic outcome rather than an engineering one. That’s the actual invention, and it’s the part that still gets miscredited.

Open Text had tried the same thing in the summer of 1996 and got run off the web for it. Two years later the identical idea worked, and Gross himself guessed why at launch: GoTo was new enough to have no reputation to taint. Nobody had a memory of GoTo as a pure thing to be disappointed by. The web had also stopped being a research network and become a place where people bought stuff.

The risk moved

Here is what separates this from every model that came before it, and it has nothing to do with search.

Under CPM, the advertiser buys exposure and eats the outcome. A thousand impressions get delivered, the invoice comes, and whether anything happened afterward is the advertiser’s problem entirely. Under pay-per-click, the publisher eats it instead. GoTo served a result and got nothing unless a human being decided to act, which meant GoTo’s revenue now depended on matching a query to an advertiser well enough to produce a click, every single time, on every single search.

The incentive stopped being traffic. It became relevance, paid for in arrears. — The History of PPC, Part 3

That inversion is why the model ate the internet, and it also explains the entire behavior of every ad platform that followed. A platform that only gets paid on outcomes will build increasingly aggressive machinery to manufacture those outcomes, and eventually that machinery gets taken out of the advertiser’s hands entirely, which is Part 9. The seed is right here, in 1998.

Self-serve, which mattered more than the auction

On June 1, 1999, GoTo shipped self-serve tooling that let advertisers pick keywords and set bids in real time with no salesperson involved. Brewer’s framing was that GoTo was the only place a small advertiser could get targeted leads at all.

Consider what that replaced. Buying media in 1998 meant an insertion order, a rate card, a minimum commitment, and a human being at an agency who would not return calls from a plumbing company in Waco. Self-serve deleted the gatekeeper. By the first quarter of 2003 Overture reported more than 88,000 advertisers, and the overwhelming majority of them were businesses no media buyer would have taken a meeting with. Bids that started at a penny were running up to a dollar by July 1998.

GoTo renamed itself Overture Services on October 8, 2001, and syndicated its paid listings into portals like MSN and Yahoo, monetizing hundreds of millions of searches it never had to earn.

Google, who thought this was disgusting

Page and Brin launched in September 1998, months after the TED talk, and published a paper that same year arguing advertising-funded search engines are inherently biased toward advertisers and away from users. They used the word insidious.

AdWords launched in October 2000 priced per impression. It only became an auction with AdWords Select in February 2002. Overture sued that April over patent 6,269,361, and Google settled in 2004, immediately before its IPO, for a package worth somewhere around $360 million. Yahoo had already bought Overture in 2003 for close to $2 billion ($1.63 billion is the figure most often cited).

So the man who invented paid search sold it for under two billion, sued the company that improved it, took a settlement, and watched that company build a trillion-dollar business on the model. Gross’s own accounting of it is short. It would have been worth trillions, but who knew?

What the auction got wrong

Highest bid wins is a clean rule and a bad one, because it optimizes for the wrong variable. A five-dollar bid that nobody clicks earns the platform nothing, while a fifty-cent bid that gets clicked one time in five earns more per impression than the five-dollar bid does. Ranking purely by bid leaves money on the table and fills the top of the page with advertisers who bought their way there and can’t hold attention. GoTo built the auction correctly and ranked it incorrectly, and the correction is worth roughly the entire difference between $1.63 billion and Alphabet.

Carryover: the vocabulary that survived

Terms established in this era and the instruments they became.

Pay-per-click · GoTo, 1998

Payment triggered by a click rather than an impression, moving performance risk from advertiser to publisher. CPC pricing, the default billing unit of search advertising.

Keyword bid · 1998

An advertiser-set maximum price attached to a specific search term. Max CPC, bid adjustments, portfolio bid strategies.

Keyword auction · 1998

Price set by competing advertisers in real time rather than by a published rate card. The Google Ads auction, run on every query.

Bid floor · one cent, 1998

The minimum price at which a keyword can be entered. Minimum bids, first-page bid estimates, floor prices in programmatic.

Rank by bid · 1998

Position determined by willingness to pay. Ad Rank, which kept the mechanism and added quality as a multiplier.

Self-serve platform · June 1, 1999

Direct advertiser access to keywords, bids, and budgets without a salesperson. The Google Ads interface and every ad manager built after it.

Search syndication · Overture, 2001

Paid listings distributed onto third-party properties that didn’t sell them. Search Partners network, syndicated feeds.

Disclosed paid placement · 1998

Ads shown inside results with the price or the paid status made visible. The Sponsored label and the FTC disclosure rules behind it.

Performance pricing · 1998

Advertiser pays only on a defined action. Target CPA, target ROAS, and every outcome-priced bidding model.

Click fraud · early 2000s

Clicks generated without purchasing intent, charged to the advertiser anyway. Invalid traffic filtering, invalid click credits, IVT auditing.
