The Auction Liquidity Flywheel
In an auction-based marketplace, scale doesn't just cut your costs — it raises your revenue per unit, so overpay for distribution on purpose.

Most businesses think of scale purely as a cost advantage. Google discovered a second, more powerful dynamic: because search ads are sold through an auction, every additional user and advertiser deepens the marketplace's liquidity, which raises the clearing price of every keyword. More searches attract more advertisers, more advertisers create better price discovery, better price discovery raises revenue per search, and higher revenue per search funds even more aggressive distribution spending. Recognizing this loop early let Google justify paying distribution partners revenue shares as high as 85-100%, and to overpay for placements like the Google Toolbar, because their true lifetime value per acquired user was far higher than any competitor's. Once ahead in the loop, it becomes structurally uneconomical for rivals to keep pace.
Origin
Emerged as Google's ad business scaled through 2001-2003 and the team realized every new user and advertiser they acquired was worth more than the last, because a bigger auction pool meant higher clearing prices per keyword.
Core principles
- 01Scale economies can increase revenue per unit, not just decrease cost per unit, in liquidity-driven marketplaces
- 02Calculate true lifetime value per user before setting a distribution budget, not blended averages
- 03Being willing to overpay for distribution today can be rational if your monetization curve is still rising
- 04Being private (no quarterly margin pressure) can be a strategic advantage when executing this loop
How to run it
- 1
Identify if your marketplace has increasing returns to scale
Check whether more participants (buyers and sellers) actually raises your average revenue per transaction, not just your total volume — this is true in auction-based systems like search ads.
- 2
Calculate true lifetime value per acquired user
Estimate what a new user is actually worth over their lifetime given current and projected monetization, not just this year's average revenue per user.
- 3
Deliberately overpay for distribution
Use the gap between your LTV and competitors' LTV as a war chest — offer partners revenue shares or guarantees that look irrational by traditional margin math.
Pro tip Being a private company without quarterly margin scrutiny makes it easier to make these aggressive, seemingly irrational bets.
Watch out This can be a bet-the-company move if your monetization assumptions are wrong — Google's AOL deal risked bankruptcy if performance didn't hold.
- 4
Funnel new volume back into the marketplace
Route acquired users and their queries back into the same auction system to deepen liquidity and raise the market's clearing price further.
- 5
Reinvest the resulting revenue gains into more distribution
As clearing prices rise, use the incremental revenue to fund the next round of even more aggressive distribution deals.
- 6
Repeat until competitors can no longer match your economics
Because your per-user monetization keeps compounding ahead of competitors, they eventually cannot justify matching your distribution spend without losing money.
In the wild
Google paid software makers like Adobe, RealNetworks, and WinZip to bundle the Google Toolbar with their installers, even though toolbar users generated roughly $8 more in annual revenue than average users.
→ Toolbar users searched seven times more often than typical users, and the acquisition cost was far below the lifetime value gained, funding years of further distribution deals.
In 2002, Google agreed to share 85% of ad revenue with AOL and guarantee AOL at least $100 million, despite not having that much cash on hand if the new AdWords system underperformed.
→ The deal paid out $35 million in the first half-year alone and $200 million in 2003, making Google a dominant paid-search player almost overnight.
Common mistakes
Benchmarking against competitors' distribution spend
Inktomy publicly dismissed Google's aggressive distribution deals, arguing 'Google takes your users, doesn't help you build your property' — missing that Google's marketplace liquidity made every acquired user worth structurally more.
Treating distribution deals as one-off costs
Viewing a large guaranteed revenue-share deal purely as a cost/risk line item rather than a compounding investment in marketplace liquidity leads companies to underbid for the same distribution opportunities.
Is it for you?
Not ideal for
Businesses without an auction- or bid-based revenue mechanism, where added scale only reduces costs and doesn't also raise per-unit revenue.
From the transcript
“Keyword bids drive up price in auctions. The price creates more revenue for Google. More revenue for Google means they can pay more for distribution.”
“In this auction-based marketplace system, it's increasing returns to scale.”
