How to train a conversational chatbot

Conversational chatbots are designed to do more than chat. Their purpose is to let you scale your business faster and more efficiently.

How? By automatically and instantly resolving your customers’ most common questions, so your team can focus on the conversations only humans can resolve.

If you are using Intercom or another live chat tool on your website already, you’ve probably received a number of conversations where customers just say “Hello” or “Hi,” and then it’s up to your team to figure out what they need help with.

“Some people worry that bots might disrupt or interrupt conversations or relationships with your customers, but that’s not the case here”

A chatbot can reply to these vague conversations and find out what your customer needs help with. If it’s a very common query that the chatbot recognizes, it will provide an instant answer. If not, the query will be routed to your team to solve.

Some people worry that bots might disrupt or interrupt conversations or relationships with your customers, but that’s not the case here. With basic training, we’ve found that our chatbot Resolution Bot enhances the relationships businesses have with their customers.

Is a conversational chatbot the right solution for your business?

If your team is getting the same queries over and over again, and having to come up with ways to answer the same questions, then a conversational chatbot is likely a good solution.

Some support chatbots can resolve customer issues right in the conversation, while others direct customers to the help center article that best matches keywords in their question. While both help customers get what they need, fast, we believe chatbots are most powerful when they deliver immediate resolutions, not ask customers to look for their own answers.

At Intercom we use Resolution Bot to do just that – provide real solutions to customers’ problems. Resolution Bot can analyze conversation history, identify common questions, and surface them to team members who can turn them into answers.

Here’s what Resolution Bot has taught us about how to train a conversational chatbot:

How do you train a chatbot?

“Training a chatbot” might sound complex, but in fact it’s much more straightforward and intuitive than you might imagine.

“Training a chatbot is much more straightforward and intuitive than you might imagine”

Quite simply, you choose a common question, train the chatbot to recognize it, then create the answer. Once you set the answer live, the chatbot will reply to every customer who asks a matching question. The more answers you create, the more hours you save your team every week. We found that on average over the last year, our chatbot Resolution Bot helped businesses give customers back 109 hours of time.

Pro tip: When you choose a chatbot for your team, make sure it’s fully customizable so you can distinguish between the types of queries you want it to handle versus the types of queries you would prefer to have your team look at.

Training Resolution Bot for our own website helped us narrow down the three steps you should take for maximum effectiveness. Keep in mind that depending on what kind of chatbot you pick, there will be nuances in the way you train your chatbot and measure success.

1. Train your chatbot to recognize common customer questions

Your first task is to come up with the questions your customers most frequently ask. Resolution Bot, for example, can automatically identify and surface common questions from your conversation history, which makes it easier to spot the questions that your customers are asking the most.

Pro tip: If you have global customers, pick a chatbot that can deliver answers in different languages.

When you create an answer, you’ll want to make sure your chatbot recognizes all the potential variations of those questions as well. So gather your team and have everyone collate the various ways that the same question can be or has been asked before.

The aim of the game isn’t to have your chatbot take over from your team for all customer queries. Rather, it should minimize the time your team spends answering common or transactional queries and allow them to focus on resolving more complex questions that require hands-on assistance.

2. Create answers for a broad range of topics

As well as individual questions, you should focus on covering the various topics that customers are focusing on in their queries. Create answers for each of the most common topics, so your chatbot can cover more questions and provide instant resolutions more often.

Some common examples might include “subscription,” “password,” “delivery,” or “billing.”

This is an example of how our analytics team clustered our most commonly referenced topics in order to inform the questions we now use Resolution Bot to solve.

3. Answer many questions on the same topic

Within each individual topic, customers ask different questions. You should also create answers for each common question you receive within a single topic. For example, if your topic is “invoices,” your list of common questions might be:

  • Where can I view my invoices?
  • How do I change my invoice address?
  • How often will I receive invoices?

As you can see, each of these questions are closely related to one topic, but require different answers. By creating many answers within a single topic, you’ll help your chatbot understand the nuances between questions, so it can deliver accurate answers more often.

4. Optimize your underperforming answers

Regular maintenance on your chatbot is crucial, too. Your team should constantly review how well each answer performs so that they can improve those that aren’t doing well. Resolution Bot helps us do that by allowing us to see answers that are underperforming.

That way, we can narrow down a section of answers and look at their training, qualifiers (specific words that determine whether an answer is sent), or the answer itself to see if it’s something we can improve or remove.

Remember, training a chatbot isn’t a one-off task. You should choose a member of your team to regularly create and review answers, to ensure you maximize its effectiveness. By constantly expanding your chatbot’s coverage, you’ll provide more instant resolutions, create a more efficient team, and make your customers (and teammates) happier.
