INTRODUCTION

English translation pending.

CORE DEFINITION

Cross-selling, a standard practice in retail and platform commerce, recommends a complementary or accessory product to a customer who has already decided on a purchase. Its core proposition is that an existing purchase reveals adjacent needs, so satisfying them raises both revenue and the customer's sense of being served. The key qualifier is relevance: a recommendation only works when it genuinely fits the customer's situation, since unrelated offers convert a service into a nuisance.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Intent reading: infer the adjacent needs that are implied by what the customer is already buying. - Timing choice: place the recommendation where the customer can still realistically act on it. - Relevance filter: offer only what the purchase makes plausible, never just whatever needs selling.

Anchor fast decisions

A completed purchase is evidence of a live need, and adjacent needs usually surface at the same moment. Recommending then costs the customer little attention and saves a separate search, so the offer reads as help rather than interruption. Revenue rises because the marginal cost of the second sale is low, and satisfaction rises when the suggestion actually fits.

Sherlocking

Sherlocking refers to the phenomenon where a platform owner copies the features of a third-party developer's app and integrates them into the platform, thereby rendering the third-party app obsolete. The term originates from Apple's Sherlock search tool, which was introduced in Mac OS 8.5 and later incorporated features similar to those of third-party search utilities like Watson, leading to the coining of the term.

Beat Frequency

The term "beat note" or "beat frequency" originates from acoustics, referring to the interference of two sound waves with similar but different frequencies. The resulting interference signal has a frequency equal to the absolute difference between the two original frequencies, hence the name. This concept is also applied in optics and electronics, where combining two signals of different frequencies yields a new signal with a frequency equal to their difference. For example, consider two sine waves with equal amplitude, no phase difference, but slightly different frequencies.
