⚠ Advertising Makes the Results WorseModerate threat

Allegro (ALE) — threat to the moat

Every sponsored placement is a slightly less useful answer on the page that produced the traffic.

Allegro's best margin comes from selling positions in the list of things a buyer is shown, and the buyer came for the list.

Every sponsored placement is a slightly less useful answer on the page that produced the traffic.

At 2,1% of gross merchandise value and growing 29,7%1, advertising is being extracted from the same page that produces the traffic. The tension is arithmetic: a sponsored result is by definition not the result the ranking would otherwise have chosen, so each one traded makes the page marginally worse at its job.

Marketplaces have run this experiment before and the failure mode is well understood — the shopper stops trusting the first screen, starts scrolling, and eventually starts checking elsewhere. Allegro owns Ceneo2, which is where "elsewhere" would begin, but a comparison fee is a poor substitute for a 12,43% take rate.

The company shows no sign of having pushed too far. GMV per active buyer grew 10,4%3 and the relational net promoter score is 834, neither of which is consistent with a degraded experience.

The falsifier is the pairing of advertising share and buyer behaviour. Advertising rising past 2,1% while GMV per active buyer keeps growing means the load is tolerable. Advertising rising while spend per buyer stalls would mean Allegro is monetising attention faster than it is earning it.
