Product Led Growth with CX Metrics

We are all competing in the End User Era now.

Investor Blake Bartlett coined the term “End User Era” to capture an important shift that is happening on an organizational level across industries: “Today, software just shows up in the workplace unannounced. End users are finding products on their own and telling their bosses which ones to buy. And it’s all happening at lightning speed.”

Companies like DocuSign, Slack, Zoom, and Hubspot are examples of SaaS companies that are thriving in the End User Era. Their success is rooted in products that end-users love. Product Led Growth codifies this end user-focused growth model. PLG relies on the product itself as the primary driver of customer acquisition, conversion and expansion. This approach goes all-in on end user ease and productivity to drive growth, and is a radical shift away from the acquisition growth model so familiar in the software industry.

Customer experience (CX) metrics have an important role to play in this strategy—something we explored in-depth in a previous post: Customer Experience in the Era of Product Led Growth.

Customers Will Tell You Where Your Product Led Growth Bottlenecks Are

Metrics are essential to understanding progress on the product led growth curve. Typically the PLG model evaluates business and pipeline health based on user actions (clicks) and subscription revenue.

This is where CX metrics are so valuable. Voice of customer data illuminates the “why” behind the clicks and the cash. Classic CX surveys like NPS, PSAT, CSAT, and Customer Effort Score(CES) monitor customer sentiment—providing critical insight into behavioral and revenue metrics.

By analyzing the open-ended comments that accompany the rating-scale questions you can identify positive and negative themes in what customers are saying. Based on what you learn, you can confidently prioritize improvements to your product that will remove bottlenecks, the enemy of PLG success.

At the core, product led growth is about taking tasks that would traditionally be done manually and putting them into the product to create efficiency and a better customer experience. Step back and map out all of the steps in your funnel from acquiring an initial lead all the way through to turning that lead into a paying customer who sees value in the product. Where are the bottlenecks?

How do you know where your bottlenecks are, and whether you are eliminating them?

Let’s explore each metric to understand how it can help you identify and address bottlenecks, with real-world examples from our customers.

Net Promoter Score (NPS): Loyalty and More

Net Promoter Score (NPS) surveys ask customers to evaluate how likely they are to recommend your product or company to a friend or colleague, this “propensity to refer” is an excellent predictor of future growth.

Unlike the other metrics covered here, which are flexible and easily customizable, true NPS surveys follow a very specific format when it comes to asking the first (of two) questions. By asking that first question in a specific way, using a standard scale, companies can compare their NPS scores to industry benchmarks. The second question, which gathers qualitative data regarding improvement opportunities, can (and often should) be customized.

NPS Surveys ask two questions…

  • Question #1: “How likely are you to recommend this product or company to a friend or colleague on a scale of 0-10?”
  • Question #2: “What can we improve about this experience?” (if they rated you 0-8) or “What did you love about this experience” (if they rated you a 9 or 10).

The first question allows you to calculate your Net Promoter Score, which is a number between -100 and +100 and serves as a benchmark for progress. For detailed information on how to calculate NPS, and what the number really means, take a look at our Net Promoter Score post.

The second NPS survey question is just as important, if not more so, than the score itself because this qualitative data tells you what you need to do to improve end user experience.

Why is NPS key to Product Led Growth? Traditionally viewed as an indicator of growth (as mentioned above), NPS is also a crystal ball when it comes to retention. NPS gives you a glimpse into the minds and hearts of your end users. It can provide a constant stream of feedback about bottlenecks and that will help you create products that enable the ease and productivity you are going for.

In short, NPS captures what’s most important to users, whether it’s documentation, training, or aspects of the product itself. NPS is typically the foundation of any CX program, and since you don’t want to get overwhelmed in the beginning, there’s nothing wrong with making NPS your sole CX metric at this stage.

NPS Example: DocuSign

DocuSign uses NPS to gather feedback on product features and pinpoint any bottlenecks in the experience. They achieve this by customizing their NPS follow-up question (the one that asks users to explain their score). In the in-app survey pictured below, Docusign asks “Tell us about your experience sending an envelope.”

Guneet Singh, Director of CX at DocuSign, believes that regardless of which metric you use, it’s vital to understand how customers feel about your product at key points in their journey. In other words, don’t wait to conduct an annual survey—gather continuous data and refine your product based on that feedback.

Customer Satisfaction (CSAT): Because Support Is a Bottleneck

Customer Satisfaction (CSAT), like NPS, is another metric you can use at various points in the customer journey. The classic use case for CSAT is following up on a support interaction, where you can ask customers about their experience:

  • Solving their specific problem
  • Working with a particular CS agent
  • Working with your company in general

CSAT surveys can use a scale ranging from “very satisfied” or “very dissatisfied,” often followed by a question that asks the user to share the reason behind their score.

What makes this touchpoint so vital from a PLG perspective? Support calls, by definition, are a point of friction—nobody contacts customer support when things are going right.

Product Led Growth endeavors to eliminate support interactions altogether. When was the last time you reached out to customer support at Slack or DocuSign? Chances are, it’s never happened. That’s the seamlessness you’re going for.

This touchpoint is a rich source of insight into frustrations that customers face. Product teams that prioritize end user experience pay close attention to feedback from support as they improve product and design new features.

CSAT Example: Glassdoor

Glassdoor, the popular site for job listings and anonymous employer reviews, uses Customer Satisfaction surveys to gather feedback on support interactions. When a support case is closed in Salesforce, end users receive a personalized CSAT survey via email.

Carmen Woo, Salesforce Solution Architect and Senior Application Engineer, holds the cross-functional CX technology vision at Glassdoor. “What is intriguing about our use case is that we use machine learning to analyze feedback. Comments are tagged by topic themes and are assigned sentiment to capture the emotion behind the user’s words.

“The [InMoment] platform allows our Support team to segment feedback by agent and other relevant business drivers to uncover insights that contribute to optimizing our support function, and it can also reveal bottlenecks that are best addressed by improving product features or design,” says Carmen.

Product Satisfaction (PSAT): Adoption and Engagement Bottlenecks

PSAT surveys are highly flexible, and they can be structured the same way you structure Customer Satisfaction survey questions—asking customers to rate their level of satisfaction with a product using a scale from “very satisfied” to “very dissatisfied” (e.g., 1-3 or 1-5) or through a binary response (e.g., “happy face” or “sad face”).

PSAT surveys are best delivered within an app, when customers are using your product and can give you fresh, timely feedback. The customer sentiment derived from PSAT surveys is the necessary complement to behavioral metrics. Sure, you can see in the clicks that users are not adopting a feature, but why? PSAT helps to answer that question and guides optimization efforts.

PSAT Example: HubSpot

Marketers that use HubSpot, the popular CRM software, may recall responding to a Product Satisfaction survey when using a new feature for the first time. PSAT gives Hubspot immediate feedback on whether a new feature is delivering value to the end-user.

Even if you’ve done extensive user testing, getting feedback on a feature within the context of a user’s experience of the whole product is valuable. Is there friction? Should the feature be tweaked in some way?

This approach, which is a key aspect of lean UX design, ensures you don’t go too far down the rabbit hole with a product feature that sounded great in theory but didn’t serve your end-users in the real world. New features can bring complexity — the bain of end user ease. By continually asking for feedback in-product, you can better calibrate that balance and maintain a frictionless, easeful end-user experience.

Customer Effort Score (CES): Identify Bottlenecks in Onboarding

A seamless onboarding experience is key to widespread adoption. If end-users have to work too hard to get up and running, they’ll give up and try a competitor’s product. Even if you have an enthusiastic champion within a company, if they have to prod others to adopt or spend time convincing them of your value, their own enthusiasm will wane. As such, it’s important to evaluate how much effort end users must put into getting started.

Customer Effort Score (CES) asks how difficult it was to accomplish a given task using a predefined scale (e.g., 1-7 or 1-5). Here is an example of a CES survey:

Customer Effort Score Survey in Intercom Messenger
Example InMoment CES Survey in Intercom

CES surveys are frequently used to follow up on support calls, but they’re also extremely valuable when evaluating the onboarding experience. Success teams know that the seeds of churn can be sown in the onboarding phase. They have been using feedback from CES surveys to both (1) follow up with that customer to fix the problem and (2) develop tasks and processes that will prevent future customers from experiencing the same bottlenecks.

However, in the context of PLG, addressing onboarding feedback isn’t just the domain of the Success or Support team. It is vital input to UX teams that seek to eliminate tasks that would traditionally be done manually and put them into the product to create efficiency and a better customer experience.

CES Example: Watermark

Watermark is in the EdTech space, and they’ve taken a comprehensive approach to optimizing user experience. Here’s how they do it, starting with Customer Effort Score surveys.

Watermark has a complex onboarding and training process, so they gather data at the end of each of three phases of training using CES surveys. The feedback goes to the implementation and training teams to both (1) improve the process and (2) identify customers who may need extra support. Then, of course, they look for larger trends and modify their onboarding experience accordingly.

Watermark also measures NPS & CSAT.  NPS is measured across six product lines, and Watermark studies the correlation between NPS and renewals. Higher NPS scores predict a greater likelihood for renewal, and improving products based on NPS survey results is key to Watermark’s customer retention strategy. CSAT surveys, triggered from Salesforce Service Cloud when a case is closed, help to evaluate and improve Customer Support.

And as Dave Hansen, the CX champion at Watermark, points out, they dig into the data to identify points of friction. “The feedback we’re getting tells us that there isn’t necessarily an issue with our overall solutions,” says Dave. “You may have issues running a certain report, or you may have issues with the way you have to click through to something.”

Product Led Growth Strategy Is About End User Experience

The four CX metrics covered in this post (NPS, CSAT, PSAT, and CES) offer insight into end user experience and augment behavioral data with the voice of your customer.

Remember, don’t allow scores to be your sole focus. There is gold in the open-ended feedback you receive. Without analyzing the open-ended feedback you receive, the metrics are just benchmarks that you’ll aimlessly try to identify bottlenecks through guesswork. In the end, that won’t get you very far.

Product Led Growth is all about creating a smoother experience in the moments that matter. CX metrics and voice of the customer comments help technology companies do just that.

This week we are featuring a guest author, Peter Poer, Head of Business Development & Content at test-prep platform Magoosh. We love the creative, agile way the Magoosh team used NPS as the A/B test metric to improve their product (and student happiness.) 

Magoosh is all about making sure our students are well educated and happy.  But we’re also a data-driven business that uses metrics to make decisions — vague notions of happiness are nice, but we want numbers!

So this is the story of how we improved student happiness by A/B testing changes to our product with the goal not of optimizing clicks or conversions or revenues, but of maximizing student happiness.   To start, though, I’ll introduce the metric at hand: Net Promoter Score.

NPS: Our Reliable Referral Indicator

Net Promoter Score is a metric that tells you, on the whole, how willing your customers are to promote your product.  Customers are asked on a scale of 1-10 how likely they would be to recommend your product; 9s and 10s are considered “promoters”, 7s and 8s are neutral, and anything below 6 is a “detractor.”  Your Net Promoter Score is calculated by subtracting the number of detractors from the number of promoters and dividing by the total number of respondents.  As a result, NPS is a percentage somewhere in the range of -100% (all detractors) to 100% (all promoters).  Not to brag, but our NPS is high. Really high.

At Magoosh, NPS is one of the most important metrics we track — it helps us determine not only whether students like our customer service and user interface, but also how well our products prepare students for their exams.  And most importantly it has been a reliable leading indicator of growth in word-of-mouth referrals — our largest marketing channel.  When NPS is high, students talk about Magoosh and more people buy it!

Historically, we’ve asked students the NPS question after they’ve taken their exams (and, importantly, seen their final scores).  We do this because our products prepare students for tests, and, really, the proof is in the pudding.  You can’t fully decide if you’re willing to recommend Magoosh for GRE prep until you’ve taken the real GRE.  The downside is that it can take a while for us to see NPS change in response to product changes.  Since we’re waiting until after students are done studying to survey them, it can take months between when a student sees a new feature and when she rates our product.

Our NPS Issue: Mismatched Expectations

Because NPS is such an important metric to our company, we take changes very seriously.  Earlier this year we saw NPS for our GMAT product dip fairly significantly.  Looking into why, we discovered that several passive and detractor students were complaining that they were getting lower scores on their real GMAT than they did on their Magoosh practice tests.

Screen Shot 2015-06-03 at 2.31.45 PM

Our algorithm was telling students to expect one score, but, for some, their official reports were coming back lower — obviously a frustrating experience.  These students were still improving their scores significantly, but once you’ve got a 750 in your mind, a 700 seems disappointing!  We determined that we needed to fix our score prediction algorithm to be more accurate, but we were left with a major concern: would an improved algorithm that displayed a lower predicted score be demoralizing for students?  Which was worse for customer satisfaction — a lower predicted score while studying, or a disappointing final score after the exam?

The Challenge: Could we optimize quickly for NPS?

Normally when we have questions about what works best for conversion or marketing, we run a quick A/B test to determine what works best.  But NPS was different — we’d never A/B tested for NPS optimization before, and our NPS collection survey only went to students after their exams.  It would be months before students who saw the changed algorithm took their exams and we got back NPS data.  Making a significant change without knowing how it would affect our word of mouth marketing was a big risk.

Our Solution:  Bring NPS inside our product

We determined that in order to A/B test the algorithm change, we needed a method for collecting NPS data while students were still studying — not just waiting til the end of their exam.  We began using a third-party tool called InMoment, which allows us to ask the NPS question in our product and analyze the data in real-time.  We then deployed the changed algorithm to half of our GMAT students, and we could then match the “Likely-to-refer” rating to students in the treatment and control groups.  Suddenly NPS had a new use case for us — as a powerful, agile product tool.

It turned out that the improved algorithm did not affect student satisfaction while studying with Magoosh — NPS from both student groups was identical.  Knowing this allowed us to roll the change out to all students more quickly.  We were also able to track the students in the A/B test over time, and have seen that post-exam NPS for students in the treatment group is a full nine points higher than for the control.

Takeaways from A/B Testing for NPS

1)  Include current customers in your optimizable funnel

Our goal is always to provide our students with the best possible test prep experience.  But since we’re not able to read minds, it’s not always easy to know if what we’re doing is actually providing a great experience.  It’s easy to think of customer acquisition as a funnel, and to wrap our brains around how to A/B test to optimize that funnel.  But what doesn’t come easily (at least for most startups — and definitely not for Magoosh, at first) is to think of current customers as part of an optimizable funnel too.

2)  Optimize your products for referrals

If your business is built on recommendations and word-of-mouth, then you really can’t afford not to optimize your products for referrals.  This process has helped us make sure that what we’re doing is making a meaningful difference for students, and has provided us with a useful and repeatable framework for testing future features and products.

3)  Focus on agility

Shift your thinking on NPS from a one-time transactional model to an ongoing and contextual model.  In-product NPS tools available today like Wootric can help you do this easily, as well as keep track of your A/B test groups.  You can speed up decision making and keep your pulse on customer happiness.
