Brief

Landingfolio added a new ad bidding system: 4 available sponsorship slots with 5 advertisers competing, which will force one advertiser off the roster and trigger a notification. Creator Danny Postma launched the system to discover what to charge for sponsorships and is treating the live auction as a pricing experiment to observe price dynamics.

Why it matters

The platform on Landingfolio now runs 4 ad slots while 5 advertisers are actively bidding, so one advertiser will be bumped and receive a notification.

Key details

  • Danny Postma built a full advertising bidding system to determine sponsorship prices and is running this live pricing experiment with early participants to observe resulting price action.
Source evidence

now the fun parts starts

platform has 4 ad slots

5 advertisers are bidding

meaning one advertiser will be bumped off (and received a notification)

very curious to see what this does to price action

also, thanks for everyone participating from day 1, this is a fun pricing experiment

(i love price experiments)

I always wanted to add sponsorships to Landingfolio.

But, I didn't know what to charge for it 🤔

So I created a full advertising bidding system.
