The essentials
  • Jeff Bezos y Mark Zuckerberg cuentan con amplios datos sobre los hábitos de los usuarios.
  • Los usuarios a menudo descartan libros irrelevantes y anuncios de streaming, como los de una trilogía llamada Ruthless Faerie Werewolves.
  • Netflix sigue sugiriendo una versión teatral de Stranger Things a pesar de que un usuario solo ve una temporada.
  • Amazon suele anunciar artículos comprados recientemente, mientras que Reddit y X promocionan productos de software poco claros.

Data collection doesn’t mean better targeting

As companies across the digital landscape continue to amass vast amounts of user data, the expectation is that this information will lead to more accurate and relevant advertising. Yet in practice, this does not always seem to be the case. Everyday interactions with platforms like Amazon, Netflix, and social media often result in ads and recommendations that feel misaligned with actual user preferences and behaviors. For example, Amazon is known to display ads for items a user has already purchased, highlighting a failure in real-time data processing or predictive modeling. This inconsistency can be frustrating, especially when users have invested significant time and effort into their digital footprints.

The problem extends beyond e-commerce. Streaming services, too, have struggled with accurate personalization. A notable case is Netflix, which recommended a stage-play version of the show Stranger Things to a user who had already stopped watching the series after one season. This kind of recommendation, repeated multiple times, not only feels intrusive but also raises questions about the platform’s ability to track user engagement and preferences effectively. These instances reveal a gap between data collection and actionable insights, leaving users feeling misjudged or misunderstood.

Why do users still see irrelevant ads?

One of the most glaring examples of poor targeting is the recommendation of books with titles that clearly don't align with a user’s interests. Titles like Ruthless Faerie Werewolves or Evil Mafia Hunk are pushed repeatedly, despite the user having no history of engaging with similar content. This disconnect suggests that algorithms may be optimizing for broader trends or default recommendations rather than individual preferences. The irony is that users often have highly specific tastes, yet the recommendations remain generic or even bizarre.

The issue is not a lack of data, as the volume of personal information available is immense. The challenge lies in effectively analyzing and applying this data. Some users express a mix of amusement and concern: the former in their uniqueness not being reduced to mere data points, the latter in the possibility that the algorithm might know them better than they know themselves. However, until platforms can deliver more accurate and tailored suggestions—perhaps for niche interests like micro-histories of cod or 19th-century navigation—users will continue to question the true value of data-driven marketing.
