Two ways to answer the same question
A customer wants to know whether you deliver on Saturdays. One business has an FAQ page that answers it. The other has a chat window that answers it. Both are correct, and they behave very differently.
What an FAQ page does well
An FAQ page is cheap, fast and honest. Search engines index it, it never has a bad day, and it scales to any volume of readers. It is also passive: it waits for someone to find it, and it cannot ask a follow-up question.
What a chatbot does well
A chatbot starts the conversation. It answers the specific version of the question the customer actually has, it can ask what they need, and it can collect the details that turn a browsing visitor into a booking. It also works at 11pm.
Where each one falls down
An FAQ page cannot tell the difference between a price shopper and a buyer, and it cannot help someone who does not know which question to ask. A chatbot without good source material will confidently invent an answer, which is worse than saying nothing.
The rule we use: the chatbot should only ever say what a knowledgeable member of your team would say, and hand over the moment the conversation goes somewhere new.
The version that works
Keep the FAQ page. It earns search traffic and answers the common questions for free. Put a chatbot on top of the same content so the questions that need a conversation get one, and route anything unusual to a person with the full history attached.
That combination handles most of your inbound volume, keeps your team on work that needs a human, and gives you a transcript of what customers actually ask, which is the most useful marketing research you will ever get.
