Summary

Interviewed at DoorDash for a product analytics role and got hit with a metrics definition question about Yelp reviews. Not a lot to go on from the session but it was enough to make me think harder about how I frame success for user-generated content products.

Author's notes

I went straight to volume of reviews and average rating, which in hindsight was pretty shallow.

Suggested Approach

Start by clarifying the goal of Yelp reviews (e.g., helping users make informed decisions, driving business value) and then define success metrics across user, business, and platform dimensions. Structure your answer by mapping metrics to the review lifecycle: creation, consumption, and impact, and tie them to DoorDash's context if relevant.

Pro tip: Emphasize that metrics should be actionable and balanced—avoid vanity metrics and consider counter-metrics to prevent unintended consequences like spam or bias.

1. Clarify Objectives

Identify the primary goals of Yelp reviews: helping consumers choose businesses, providing feedback to businesses, and generating content for the platform.

2. Map User Journey

Break down the review lifecycle into stages: writing, reading, and acting on reviews, and consider metrics for each stage.

3. Define Metrics by Category

Propose metrics for quantity (e.g., number of reviews), quality (e.g., helpfulness votes, sentiment), and impact (e.g., conversion, business engagement).

4. Prioritize and Balance

Select a few key metrics that align with business goals and include counter-metrics to monitor trade-offs (e.g., review volume vs. spam).

5. Connect to DoorDash Context

Relate metrics to DoorDash's ecosystem, such as how reviews influence restaurant orders or dasher performance, if applicable.

Key Points to Mention

  • User engagement metrics: review submission rate, helpfulness votes, read-to-action ratio
  • Content quality metrics: average rating, sentiment analysis, review length, photo attachments
  • Business impact metrics: conversion rate from review page to order, business response rate, revenue lift
  • Platform health metrics: spam detection rate, review authenticity, diversity of reviewers
  • Counter-metrics: review volume vs. quality, rating inflation, bias in reviews
  • DoorDash-specific: integration with restaurant ratings, impact on delivery experience
