G2 and Trustpilot review monitoring: capturing weak signals

Luna Team2026-04-245 min read

Online reviews are the raw voice of the market. They reveal your competitors' customer frustrations — and your opportunities.

Why monitor competitor reviews

G2, Capterra, and Trustpilot reviews contain information unavailable elsewhere:

  • Undocumented product weaknesses
  • Recurring support issues
  • Most-requested features
  • Real satisfaction vs. marketing

What Luna detects

Satisfaction drops

When a competitor's G2 score drops 0.3+ points in a month, Luna alerts you. This is often a sign of a product issue or unpopular change.

Recurring themes

Luna analyzes review text and identifies emerging themes: "slow support," "price increased," "frequent bugs." These patterns become sales arguments.

Direct comparisons

Reviewers often mention other products. Luna captures these comparisons to enrich your battlecards.

Integration into your strategy

Review insights automatically feed:

  • Battlecards: weaknesses confirmed by users
  • Win/Loss: switch reasons mentioned
  • Alerts: satisfaction drop = prospecting opportunity

Monitored sources

  • G2 (public profiles)
  • Capterra (reviews and ratings)
  • Trustpilot (verified reviews)
  • Product Hunt (launch comments)
  • Apple Podcasts (mobile app reviews)

All these sources are public and require no paid API.
