Advertising what you cannot sell

It is 11.11, and by noon the most expensive ad on many accounts will be for something that sold out at nine.

Not the hero campaign. The catalogue feed. Every product with a price and a picture, matched to whoever was looking at something like it, spending on its own while the team watches the big offer. It was the best performer last week. It will be the worst by lunch.

The item with the deepest cut goes first, because that is what a deep cut is for. Stock reaches zero around nine. The product page changes to a greyed-out button and a line about being notified. The feed does not change, because it reads the catalogue on a schedule, hours apart, so the ad keeps its price, its picture and its click-through rate, which stays high, because the offer is still excellent. The only thing that has changed is that the click now lands on a page that says no.

From the platform side it is the most common 11.11 error I have watched. Nobody was away. The room was full, the dashboard was open, and the offer was good. It was advertised for three hours after it stopped existing, to people who wanted it, at the highest auction prices of the year, and the click-through report will call those three hours the campaign's best.

Scarcity is the story of the day. Every banner says limited, every countdown says hurry. For once it is true. The one system in the company that has no idea it is true is the one buying the traffic.

The real job of the ad on 11.11 is to know what is left, faster than the customer finds out, and to point at that instead. Selling was never the hard part.

On the one day scarcity is real, the ad should be the first thing in the company to know. It is usually the last.
