Post-Chat Survey

Post-Chat Survey

A post-chat survey is a short question shown to a visitor immediately after a chat conversation ends, asking them to rate the help they received. It is the standard collection mechanism for customer satisfaction scores in live chat, and the fastest feedback loop a support team has.

TL;DR

The one-question rating shown when a chat ends. Short surveys get answered; long ones get closed, which is why almost every implementation is a single tap.

Key Points

The survey is the delivery mechanism; [[customer-satisfaction-score]], [[customer-effort-score]], and [[net-promoter-score]] are the metrics it can carry [1].

Response rates fall sharply with length — a single-tap rating typically outperforms a multi-question form by a wide margin.

Timing matters: shown at the moment the chat closes, while the experience is fresh, rather than emailed hours later.

An optional free-text box after the rating is where the actionable detail lives, even though most people skip it.

Ratings are self-selecting — unhappy and delighted customers answer more often than satisfied ones, so the average overstates both tails.

Pairing survey results with a [[conversation-tag]] turns a score into a diagnosis: which topics produce low ratings, not just how many.

What to ask

Most teams ask a satisfaction question — 'How would you rate this conversation?' — on a two-point (thumbs), three-point, or five-point scale, and compute Customer Satisfaction Score (CSAT) as the share of positive responses [1]. The alternative worth considering is a Customer Effort Score (CES) question: 'How easy was it to get your issue handled?' Effort correlates better with future loyalty than satisfaction does, because customers rarely churn over a pleasant conversation that solved nothing. Net Promoter Score (NPS) is a poor fit here — it asks about the company as a whole, and a support interaction is the wrong moment to sample it. Whichever you choose, ask one question, keep the scale consistent over time so trends mean something, and put the optional comment box after the rating rather than before it.

Reading the results honestly

A post-chat survey measures the customers who chose to answer, not the ones you served. Silence is the majority case and it is genuinely ambiguous — a visitor who got a fast answer and closed the tab looks identical to one who gave up. That makes the absolute number less useful than the trend and the breakdown. Slice by topic using a Conversation Tag, by operator, and by hour of day; a score that drops only outside Business Hours is telling you about coverage, not quality. It is also worth reading low ratings alongside the Chat Transcript, because the rating says something went wrong and the transcript says what. Where volume is thin, Sentiment Analysis over every conversation gives a broader if noisier signal than a survey answered by a fraction of visitors.

Implementation details that matter

Show the survey when the conversation genuinely ends, not when the widget closes — a visitor who minimises the chat and returns has not finished. Keep it inside the widget rather than redirecting anywhere. Do not gate it behind a login or ask for an email, since both convert an easy tap into a decision. Handle the Offline Message case separately: rating a conversation that never got a reply measures availability, and mixing that into the same score muddies both. Finally, close the loop internally — a survey nobody reads is worse than none, because it spends customer goodwill for nothing. The useful cadence for a small team is a weekly scan of every low rating with its transcript, which is a handful of minutes and consistently surfaces the First Contact Resolution (FCR) failures worth fixing.

Customer Satisfaction Score (CSAT)

Customer Satisfaction Score (CSAT) is a support metric that measures how happy a customer is with a specific interaction, product, or service, usually captured by a short post-interaction survey. It is expressed as the percentage of respondents who rate their experience as satisfied or very satisfied.

Customer Effort Score (CES)

Customer Effort Score (CES) is a single-question survey metric that measures how much effort a customer had to expend to get an issue resolved, a question answered, or a task completed. The premise is that lower-effort interactions drive higher loyalty and retention.

Net Promoter Score (NPS)

Net Promoter Score (NPS) is a customer-loyalty metric derived from a single survey question that asks how likely a customer is to recommend a company, product, or service to a friend or colleague, scored from 0 to 10. The score is the percentage of promoters minus the percentage of detractors, yielding a number between -100 and +100.

Chat Transcript

A chat transcript is the complete, timestamped written record of a live-chat conversation between a website visitor and a support operator or chatbot. It captures every message in sequence, usually alongside metadata about the session, and can be archived, exported, or emailed for later reference.

Conversation Tag

A conversation tag is a short label attached to a support conversation (or an individual message within it) that classifies its topic, intent, or status so the team can search, filter, route, and report on it later.

Sentiment Analysis

Sentiment analysis is the automatic classification of text by the emotion it expresses — typically positive, negative, or neutral. In customer support it is applied to chat messages and transcripts to flag frustrated customers, route conversations, and measure how people feel about a product without waiting for a survey.
