Gross made advertisers pay only for the click, not the guess that someone would make one
问题
Web advertisers paid upfront for banner impressions with no way to know whether anyone actually cared
背景
Online advertising in the mid-1990s copied print and TV: buy a block of impressions, pay per thousand views, and hope. Gross later described the model bluntly as buying ads, crossing your fingers and hoping it worked out, because an advertiser paying for exposure had no built-in signal for whether that exposure did anything. Search engines had the added problem of needing revenue without corrupting results — ranking pages by who paid the most for placement, with no other pricing signal, risked flooding results with irrelevant paid listings dressed up as answers.
Charging advertisers more for a bigger banner or a longer campaign wouldn't fix the underlying disconnect between payment and outcome — the industry needed to tie the money changing hands to something the advertiser actually wanted, which was a visitor arriving at their site, not merely an ad being displayed to someone who might ignore it.
换别人会怎么做
The available model was selling fixed blocks of banner impressions priced per thousand views, the same way print and TV ads had always been sold — advertisers paid whether or not anyone engaged, with no mechanism connecting the price to any actual response.
他们看到了什么
Advertisers weren't paying for what they wanted, only a proxy of it. A click was the real unit of value — proof someone acted — closing the gap between what got charged and what was delivered.
那一手
Gross launched GoTo.com so advertisers bid, in an open auction, for placement against specific search keywords, and paid only when a user actually clicked their listing rather than whenever it was merely shown. Competitive keywords commanded higher bids and pennies bought placement on obscure ones, letting the market price attention directly instead of the advertiser paying blind.
为什么管用
Charging per click meant an advertiser only paid when the ad demonstrably worked, which removed the risk that had made impression-based buying feel like a bet, and letting bids set price via auction meant the market, not a rate card, decided what a keyword's attention was worth. That alignment between payment and outcome is what made the model self-funding for search engines without corrupting result quality, since paid listings were kept separate and advertisers self-selected by what a click was worth to them.
值了多少
Google adopted the same click-priced auction for AdWords in 2002 and paid Gross's company roughly $360 million to settle patent claims.
什么时候会失灵
Pay-per-click breaks down when clicks themselves can be faked or gamed, as click fraud later showed, and it only works where a click is a meaningful, trackable proxy for value — for brand advertising aimed at awareness rather than a specific action, charging per click misprices what the advertiser is actually trying to buy.
后来呢
Pay-per-click auction pricing became the default mechanism for virtually all search and much of digital advertising worldwide, and Gross's own missed patent filing on it became a cautionary story he calls a trillion-dollar lesson.
