6 Effective Questioning Techniques for Customer Service

Questioning Techniques

If you are looking for types of questioning, or questioning techniques,  you can use in customer service, then look no further.

We examine six key techniques for questioning customers, listing lots of helpful probing questions and skills along the way.

Effective Customer Service Questioning Techniques

Asking the right questions gives us the information we need when we need it. It is therefore an invaluable skill for customer service teams.

Fortunately, there are lots of questioning techniques that advisors can use to develop this skill. We have listed six of the best below.

1. Open and Closed Questions

An open question is a question that starts with “how”, “what”, “when”, “where”, “who” or “why” and cannot be answered with a simple “yes” or “no”.

You will likely use open questions when:

  • You want to help change the mindset of the customer
  • You want to better understand the customer
  • You want to show interest in what the customer has to say

For these reasons, advisors are often recommended to ask open questions as often as possible and then to follow up with a closed question when they want to confirm their understanding of something.

As you may have guessed, a closed question is the exact opposite of an open question. So these are questions to which the customer can only answer “yes” or “no”.

Below are some examples of open and closed questions which will help to reaffirm your understanding of the distinction between them.

Open Questions Closed Questions
How can I help you? Can I help you?
How did you feel about our service today? Did you experience good customer service today?
Which features of our service do you like most? Do you like our service?
What are you looking for? Are you interested in buying something?
What would make you consider using our service again? Would you consider using our service again?

One word of caution, though, before using open questions, is to be wary of stacking questions. This means asking two or more open questions at once.

For example, if you ask a customer: “Why are you unhappy with our current service? And how much money do you think you could save moving elsewhere?” The customer will generally only answer the last question, even though it might be of lesser importance.

2. Probing Questions

A probing question is a question that you ask to gain greater insight into what someone has just told you.

Asking probing questions in customer service can help you improve the overall experience by responding to a customer’s actual needs instead of making assumptions. It can also help to improve First Contact Resolution (FCR) rates.

We have put together some sample probing questions – also known as probe questions – that can help gather more information and better understand customers’ feelings:

  1. “Just to make sure I’m not missing anything, can you please tell me what you were doing when the issue first began?”
  2. “Just to make sure that I fully understand the problem, could you give me an example of what you mean by…?”
  3. “What impact has this had on your…?”

For examples of probing questions, read our article: 15 Example Probing Questions to Better Understand Your Customers

3. Funnel Questions

Funnel questions, (also known as Funnel Questioning or the Questioning Funnel), derive from something called “The Funnel Effect”. The Funnel Effect works in three phases, as highlighted in the graphic below.

A diagram discussing The Funnel Effect in Questioning Techniques

Step 1: Asking Open Questions – Try to start with open questions about the subject at hand, as this will give you all the information you require to take the conversation further.

Step 2: Asking Probing Questions – These are the questions which will allow you to delve deeper into the customer’s answers to your open questions, finding out the reasons and emotions behind those answers.

Examples of these funnel questions to probe for information include:

  1. Could you give me an example of what you mean by…?
  2. How long has this been an issue?
  3. Is there anything you can tell me about how it looks or sounds?
  4. What happened when you tried to…?
  5. What were you doing when this started?

Step 3: Asking Closing Questions – Asking closed questions allows you to confirm both your own and the customer’s understanding of what has been discussed in that specific line of questioning.

When you string together your questions in this fashion, they are known as funnel questions. These provide a nice guideline for contact centre advisors to use.

However, Lindsey, one of our readers, warns: “Try not to use it rigidly, as the advisor may need to confirm the information they receive from an open question with an immediate closed question.”

You don’t need to stick to the principles of the Funnel Effect. Sometimes it’s better to use them intermittently.

Also, the advisor may need to open with a closed question to immediately confirm that they are speaking with the right person.

So while it’s good to use all three question types, you don’t need to stick to the principles of the Funnel Effect. Sometimes it’s better to use them intermittently.

4. TED Questions – (Tell, Explain, Describe)

When using probing questions, TED can become your best friend. TED stands for three simple words that will help you get the answers you are looking for: tell, explain and describe.


Some examples of TED questions include:

  • Tell me, how will that affect you?
  • Tell me, has this happened before?
  • Tell me, what was your main motivation for calling?
  • Explain to me, what impact has this had on your…?
  • Explain to me, how did this situation begin?
  • Explain to me, what difficulties did you face when you tried to…?
  • Describe how you felt about that
  • Describe how it looks
  • Describe your ideal outcome

It can be great to use these TED questions to probe customers when the advisor feels as though they have heard something that they would like some more information on.

These probing TED questions help to pinpoint the relevant insight from a customer’s open response and can therefore work well when used between open and closed questions.

The style of wording also helps to prompt the customer into giving the advisor all the relevant information in regard to their query.

As Gordon Walker, a contact centre trainer, says: “By starting a question with one of these words, you are essentially demanding an answer from the customer without letting them know that you are.”

5. Leading Questions

A leading question is a question that suggests a particular answer and can be used well in customer service and sales to attempt to influence a response.

These questions are therefore a form of persuasion and can work particularly well when dealing with a fence-sitting customer who is struggling to make a decision.

To use leading questions effectively in these scenarios, it is best to set them up with an open question, such as: “What features are most important to you?”

When the customer responds, you can then relate the feature to an option and use a leading question to position that question in a favourable way – just like in the example below.

A graphic showing how to use leading questions

Some other examples of leading questions include:

  • Option A comes with free delivery, so if you use our service regularly, over time you will save money. Would that add value for you?
  • With Option B you have a quality guarantee. Is that the kind of thing you were looking for?
  • Most customers with the same needs as you opt for Option C. Would you like me to explain why?

From these examples, we can see that leading questions are designed to make the customer say “yes”, which can be a powerful tool in the art of persuasion.

But remember when dealing with angry customers it can be perhaps even more persuasive to do things like offer free trials, to help minimize the risk for the customer.

6. Signposting

Signposting is a great way to set up questions to help customer conversations flow and engage customers.

This technique centres around the phrase: “In a moment.” So, you will be using statements like:

  • “In a moment, I’m going to ask you for a reference number.”
  • “In a moment, I will need to ask you for your bank details.”
  • “In a moment, you will need a pen.”

These little phrases will stop customers rummaging around their house for pens, credit cards etc., because you have already given them that little heads-up.

Not only will this save time on calls, but it will allow customers to think through what will be asked of them, so they can fully prepare and properly think through how they will respond to your questions.

Probing Techniques to Improve Your Questioning

When we probe customers, we are looking to gather more insight into something that they have just told us. Probing techniques like those below will help you to do this.

You may also find these techniques useful when uncovering the customer’s intended call outcome or when they don’t sound overly happy with the course of the conversation.

1. Customer Validation

The simplest probing technique that you can use to elicit more information from customers is to actively validate the little pieces of information that they give you.

By using statements like those below, an advisor can show an interest in the little things that the customer is saying, to create an environment where the customer feels actively encouraged to talk more.

  • “I think that you’ve made a great decision.”
  • “I understand why you chose that option.”
  • “I can see what you were trying to do there.”

With the help of these phrases, we can also reassure the customer of their previous choices, if they seem anxious about their previous decision-making. We can support them by demonstrating an understanding of their thought process.

Just remember to use an upbeat, authentic tone to avoid patronizing the customer. Smiling while speaking is a good tip to help you achieve that.

2. Push and Pull Communication

People communicate in different ways. If we can communicate with customers in the way that best suits them, they will respond better to our probing.

Fortunately, this doesn’t have to be complicated, as customers will generally prefer one of two methods of communication. These are:

  1. Push Communication – Which is to ask lots of questions of the customer.
  2. Pull Communication – Which is to share lots of information with the customer.

For more on using these two methods of communication, while better controlling calls, check out the video below, which comes from Carolyn Blunt of Ember Real Results.

Knowing when to use either method of communication will enhance your probing skills and is a simple way to improve customer experience.

3. Filtering

There are many different factors that play a part in what information we let in and what we leave out when talking to customers and probing them for more insights.

In order to best communicate with customers, we want to identify their main drivers for calling and we can do this by using “filtering” as a probing technique.

Filtering helps us to determine what type of customer we are talking to and the picture below shows three key types of customer filters.

A diagram showing three types of customer filters

Once the advisor recognizes the customer’s key drivers through using these filters, they can adapt how they probe customers, if coached effectively.

Let’s take this first filter as an example, “Towards / Away from Thinking”.

When a customer wants to move towards a solution, the agent should focus their probing around finding the solution.

For example, an advisor could say: “What would be the best solution for you today, Mr Smith?”

When a customer wants to move away from a problem, the agent should focus their probing around helping the customer steer clear of the situation and prevent it from happening again.

For example, an advisor could say: “Let’s looking into finding a reason for this immediately. When did the problem first arise?”

For more on how to use this probing technique in the contact centre, read our article: Want to Speak in the Same Language as the Customer? Use Filtering!

4. Chunk It Up!

This technique is another that is all about matching the customer’s preferences in how they communicate and how much information we give them.

To use this technique, you need to understand the difference between big chunk and small chunk customers, as highlighted below.

Big Chunk Customers – These customers are focused on the big picture and want very few details.

With big chunk customers, just get to the point. When probing the customer, focus on only the key pieces of information that are needed to solve that query.

Small Chunk Customers – These customers are interested in the small details and like you to be very specific.

Small chunk customers value it when you are very thorough in your probing, so listen to them and repeat back even the minute details, to show a clear understanding.

Yet the trouble with this technique is that it may not be easy to immediately spot if the customer is big chunk or small chunk.

Considering the following questions, though, will enable you to decide for yourself:

  • When explaining the problem, does the customer go into lots of detail?
  • Is the customer asking you lots of questions in order to gather more insights?
  • Does the customer suggest that they are in a rush or would like you to get to the point?

5. Reframing the Conversation

Probing customers can be a tough task when dealing with impatient customers. Techniques such as creating probing questions unique to the customer’s situation can really improve an advisor’s ability to problem-solve, but this does take time.

For customers that seem to be in a rush, an advisor can frame the conversation differently. Telling the customer what you will do for them is the perfect place to start.

“Explain to the customer that you are going to ask them some probing questions, and tell them why you are going to ask them,” suggests Lindsey, one of our readers.

It can be good to let the customer know what’s in it for them to answer the questions. This helps to justify all questions in advance!

In addition to this, it can be good to let the customer know what’s in it for them to answer the questions. This helps to justify all questions in advance!

To use this technique, you can start by saying: “Okay, Mr/Mrs [NAME], I’m going to ask you some questions about X, Y and Z so I can give you the best possible solution to your question/issue/situation’.”

Questioning and Probing Skills

To improve questioning and probing, active listening is the most important skill to develop.

After all, advisors need to stay focused, refrain from interrupting and recap key bits of information that the customer gave them.

As Christine Knott, the former Managing Director at Beyond the Box, says: “There is absolutely no point in us asking questions if we are not prepared to listen.”

So if we want the techniques presented in this article to be as effective as possible, we are going to need to develop listening as a key contact centre skill.

Also, perhaps not to the same extent, for the most effective contact centre communication, we want our advisors to have the five following questioning and probing skills.

  1. Action Orientated – When we sense that the customer wants to have their problem solved quickly, bein able to focus on getting things moving will help to show the customer that their time is valued.
  2. Ownership – Customers who feel burdened by a problem will feel much better if an advisor actively takes ownership of the issue. This means that the customer will be in a much clearer state of mind once you begin probing.
  3. Problem-Solving – If an advisor can solve the problem, without rushing into assumptions, they can speed things up and, more importantly, make the conversation much more effortless for the customer.
  4. Patience – Customers like to feel listened to, so we must be patient during the probing process and avoid jumping to solutions before we come across those pieces of gold dust which allow us to build rapport with customers…
  5. Rapport Building – Advisors must recognize whether the customer wants lots of information or just want them to get straight to the point. If they are skilled in building rapport, they will recognize the customer’s key call drivers and modify their approach to deliver the best experience.

More Tips and Tricks for Call Control

To close this article, we wanted to share a few ideas that our readers have suggested to us on how to improve call control in the contact centre.

These techniques, which can be used throughout a customer conversation, may prove helpful when questioning and probing customers.

Flow With the Answers

The key to effective questioning is simply to listen!

By listening to your customer’s answers (the whole answer), you have time to formulate what your next question will be. This will also allow you to ensure that the line of questioning has a natural flow and doesn’t sound like a scripted checklist of things you need to ask.

By listening to your customer’s answers (the whole answer), you have time to formulate what your next question will be.

The main part of this technique is to ensure you don’t jump from one subject to another. Use the Funnel Effect and move on to the next line of questioning after confirming understanding with closed questions.

Control Silences

It is hugely important to listen to your customer. It is equally important to let the customer answer!

A thumbnail picture of Michael McGarrigle

Michael McGarrigle

If, when you ask a customer a question, they aren’t immediately forthcoming with an answer, don’t rush in to fill the gap for them. It is, after all, pointless asking a question if you are going to answer it yourself from what you believe the customer might say.

Control the silence by waiting for the customer to either answer or ask for clarification of the question if they don’t understand it.

Use Positive Words

Use positive language and be energetic and enthusiastic in your delivery, as you need to motivate someone to consider the questions you are asking.

Ideally, you want to inspire them to respond in a likewise manner and to open up the call into a conversation rather than a set of questions and answers.

Use Your Voice to Project Professional Confidence

A thumbnail picture of Christine Bryant

Christine Bryant

Use your voice to project professional confidence as your customer needs to have confidence in you, so write down what you want to say and rehearse it so that you are prepared.

Also, remember that attention should be given to ensuring that conversations are natural and not forced, while you should listen to what your customer has to say and link the answers into the next question.

With thanks to Christine Bryant

Don’t Just Ask Open Questions

There are contact centres who ask advisors to only use open questions for probing. This is with the thought that open questions will draw more information from the customer, which will allow the advisor to better attach a product or service to the customer’s needs.

However, open questions should not be used in isolation. Closed questions also have their benefits.

Open questions give information; closed questions give confirmation.

Open questions give information; closed questions give confirmation. You need closed questions as well because closed questions give direction.

You can’t hold a conversation purely on open questions because you would never confirm the information that you’ve heard and that is crucial.

When you confirm the information, it demonstrates that you have been listening and it also keeps the conversation on track – where the advisor wants it to go and the customer needs it go.

Use “Pre-Closing” for Call Control

To check that the call is going in the right direction, advisors should ask customers if they are happy and have understood everything that they have so far heard. This is called “pre-closing”.

Some examples of pre-closing questions include:

  • Are you happy with what you have heard so far?
  • Do you like what you have heard so far?
  • Do you feel comfortable with everything that I’ve said?
A thumbnail picture of Christine Knott

Christine Knott

What you are looking for is clarification that will give you a yes or a no, so you know that you are going in the right direction.

It signposts that you are checking, at different stages, that you are “pre-closing” what you’ve just heard, and you are getting a commitment from the customer.

With thanks to Christine Knott

Ask if You Can Help With Anything Else

Asking the customer if they have any other questions/anything else you can help with, at the start of a call, can aid in first contact resolution.

Asking at this point allows you to plan how your questioning will flow. For instance, it may not be possible to address the first issue raised until the second issue has been resolved.

A thumbnail picture of Gordon Walker

Gordon Walker

It is a good idea to deal with each issue individually and go for the easiest or quickest issue to resolve first. This gives the customer a feeling that you are helping them and getting results. If the customer raises a new query during the call you should deal with it before closing the call.

This technique avoids having to ask the same question at the end of the call, which can increase call handling time as human nature often means if we are asked if there is anything else, we will try to find something.

With thanks to Gordon Walker

Remember These Three Tips to Probing for Information

Relevant probing helps unearth the customer’s need and reduces Average Handling Time (AHT). We need to encourage advisors to ONLY do relevant probing when they seek answers to help customers.

Some of my key tips for probing customers include:

  • LISTEN to the main query attentively. This helps to get many cues from the query itself – hence reducing the need to probe.
  • Do open-ended probing when you need to recommend something to a customer or when the customer is facing an inconvenience. Ensure closed probing when you need the reply in just a yes or no to hand-hold the customer.
  • The context and manner of probing must be clear for the customer to understand instantly, and courteous for them to respond similarly.

Make Interaction Relevant to the Conversation

Most important is ensuring that any interaction with a customer occurs as being conversational, relevant and intelligently positioned.

Customers should never feel they are being asked a random question that has no relation to the discussion, and this can often happen when reading from a script.

Customers should never feel they are being asked a random question that has no relation to the discussion…

Effective call centre advisors should be able to gain meaningful insight and information from customers by positioning their dialogue in a manner appropriate to the individual conversation.

Throw Away the Prompts

When advisors read from a prompt, it can be hard for them to connect emotionally with callers.

An advisor that sounds interested and involved in the discussion is more likely to make the consumer feel they have got some value to gain.

Put Yourself in the Customer’s Shoes

The most effective way to develop advisors to a high standard is not to use a script and to get them to envisage themselves as the customers.

A thumbnail picture of Chris Hancock

Then they will be in a better position to understand the process and advantages to their conversations and empathize with a consumer’s decision-making process.

Empower advisors with information and support them as valued resources and they will be confident in knowing how, and when, to ask the right questions.

  • Questioning your customer is a process that needs extra care and attention. The customer should never be provoked and neither should you. The initial step is to gain permission to indirectly to question the customer on anything. To do so, you must be friendly and understanding.
