The coverage rate is a metric available in the Attlas overview dashboard that measures the quality of the responses your chat provides to users. It acts as a health indicator, helping you understand whether your chat is successfully answering the most common questions asked by your audience.

Automatic evaluation of responses

Every message sent by your chatbot automatically receives a score from 0 to 100, visible in the Conversations view. This score measures the quality of the response from the user’s perspective: did they get what they were looking for? The overall coverage rate shown in your dashboard is the average of these individual evaluations.

How to read the scores

  • 🟢 Green (85 to 100), The response is direct, accurate, and helpful. The user obtained the information they were looking for.
  • 🟠 Orange (50 to 84), The response is partially helpful. This may indicate that an off-topic question was correctly declined, or that a relevant response lacked precision on an important aspect.
  • 🔴 Red (0 to 49), The user left without a satisfying answer. Either the chatbot did not have the necessary information, or the response did not match the question asked.

Understanding the reasoning

Click on any score to display a short explanation detailing why that grade was assigned and which aspect of the response influenced the decision. This is your starting point for identifying exactly what needs to be improved.

Improving your chatbot using scores

Red scores are the most valuable to review. When analyzing them, there are two main scenarios to consider:
  1. The question was within scope, but the information was missing → This is content you need to add to your knowledge base. The more you enrich the knowledge base, the more your overall coverage rate will increase.
  2. The question was off-topic → The chatbot behaved correctly. No action is required.
Focus on satisfaction, not politeness: The score evaluates user satisfaction, not the politeness of the bot. A response like “I don’t have this information”, even if politely and perfectly formulated, is never considered a good response if the question was legitimate.
