What you'll learn

  • Explore the lifecycle of a piece of content in Pinterest
  • Discover a portfolio of metrics Pinterest developed to monitor the health of the content corpus
  • Learn the story of creating a cross-functional initiative to preserve a healthy, sustainable content ecosystem

Description

As Pinterest undergoes explosive growth in its user base, the content corpus that users contribute to also expands rapidly. The content and the machine-learning algorithms exist in a feedback cycle where content signals power the algorithms and algorithms influence the content that populates the ecosystem. A major algorithm change can significantly impact how content is exposed. Without proactive monitoring in place, the makeup of the exposed content can drift over time, in a direction that may not be the most beneficial to users.

Grace Huang offers a deep dive into the lifecycle of a piece of Pinterest content, from its birth through its growth and finally to its death, and explores how this process has changed over time. Along the way, Grace explains how a panel of metrics and a content-specific experiment framework were developed to help Pinterest gauge its content ecosystem health in different markets, helping answer questions such as how fast can we activate a piece of content absent of historical signals, do we have enough content to support a new market, and how has the makeup of the content corpus shifted over time? Grace concludes by sharing the story of how a cross-functional effort was bootstrapped to ensure that quality content can thrive in the the ecosystem and make its way to pinners who will find it relevant and engaging.
