Writing a FAQ that actually answers the questions customers ask, and feeds your AI agent
Most business FAQs answer the questions the owner wishes customers asked. Real customers ask about parking, deposits, whether you take walk-ins, and whether the price includes tax. A FAQ built from real messages answers those, and it becomes the single most useful document you can give an AI agent.
Quick answer
Pull the last hundred customer messages and list every distinct question, then write a two-sentence answer for each that stands alone without context. Include the awkward ones (cancellations, complaints, what you do not do). Group by topic, keep each answer current, and put the whole thing in your AI agent's knowledge base as plain text. Then let the agent's unanswered-questions list add to it every week.
Start from real messages
- Scroll the last hundred customer conversations and write down every question, in the customer's words.
- Merge duplicates. "Got parking?" and "where do I park?" are one question.
- Rank by frequency. The top twenty usually cover most of the volume.
- Add the ten you dread: cancellations, refunds, what you do not do, why you cost more than the shop next door.
Write answers that stand alone
An AI agent retrieves the answer, not the page, so each answer must make sense by itself. Restate the subject in the answer: not "Yes, on the first floor" but "Parking: free parking on the first floor of the building, entrance on Jalan SS2." Two or three sentences. Include the number, the time, the condition. Avoid "see above" and "as mentioned".
Q: Do you take walk-ins? A: Walk-ins are welcome on weekdays before 5pm, subject to availability. Weekends are by appointment only; book on WhatsApp and we will confirm a slot. Q: What is your cancellation policy? A: Cancel or move an appointment free of charge up to 24 hours before. Inside 24 hours, the RM 50 deposit for colour and treatment services is not refunded. Q: Do you do children's haircuts? A: Yes, for children aged 4 and above, RM 30, weekdays only. Younger children we are not set up for.
Keep it current
- Date the document and review it monthly.
- When a price or policy changes, change the FAQ the same day.
- Add every question from the agent's unanswered list that more than one customer asked.
- Delete answers that no longer apply rather than adding "update:" notes.
As the agent's knowledge
Paste the FAQ into the knowledge base as text, one Q and A per block. It usually becomes the source the agent quotes most, because it is written in customer language. Teach new answers from the unanswered list weekly; ReplyKit turns each taught answer into knowledge in one click, which is the FAQ growing itself. Details in what to put in the knowledge base.
Frequently asked questions
How many questions should a business FAQ have?
The top twenty from real messages, plus the ten awkward ones. Thirty answers cover most of the volume.
How long should each answer be?
Two or three sentences, standing alone, with the specific number, time or condition.
Should I include questions I would rather not answer?
Yes. Cancellation, refunds and what you do not do are the questions that generate complaints when unanswered.
How does the FAQ help an AI agent?
It is written in customer language with standalone answers, which is exactly what a retrieval-based agent quotes best.
How do I keep the FAQ growing?
From the agent's unanswered-questions list, weekly. Each taught answer becomes knowledge.
