The Advertiser Is the Merchant, Paying TwiceWide moat

Allegro (ALE) — moat facet

A fixed number of prominent positions and a rising number of bidders raises the price without anybody deciding to.

Allegro's advertising customers are, overwhelmingly, the same merchants who already pay it a commission.

The second toll grows more than three times as fast as the first.

The structure is worth stating plainly because it is unusual outside the largest marketplaces. A seller pays 12,43%1 for the transaction and then bids for visibility in the results, at a cost that reached 2,1% of everything sold on the platform2. Neither payment buys the customer — Allegro owns the customer in both cases — and the second is charged for prominence among sellers competing for the same buyer.

That is why advertising grew 29,7% against the marketplace's 13,4%3. The supply of prominent positions is fixed, the number of merchants bidding for them is not, and an auction with more bidders and the same inventory raises its own prices without anyone deciding to.

It is also why the flat take rate has been affordable: Allegro's effective charge to a merchant has risen even though its published rate has not.

The limit is the buyer's patience. Every sponsored result is one the ranking would not otherwise have chosen, and a results page that stops being useful costs Allegro the traffic it sells.

The measure is advertising as a share of GMV against GMV per active buyer. Both rising means merchants are paying more for an audience that is still engaged. Advertising rising while buyer spend stalls would mean Allegro is charging more for a shelf that is working less well.

Moat trajectory: Widening

A fixed supply of prominent positions against a rising number of bidders raised advertising 29,7% without any change in the published rate.

Merchants are paying more for visibility and less in commission; the effective charge is shifting from one meter to the other.
