Casper Marketing: How a Mattress Retailer Went from Zero to $750 Million in 4 Years (Case Study)


In 2014, five guys got together with an idea to build a company that would revolutionize sleep.

Their goal was ambitious and audacious: 

To create an affordable, direct-to-consumer mattress—without the need for stuffy showrooms or sleazy salespeople.

Today, their company, Casper, is valued at $750 million and serves more than 1 million customers in eight countries. (Source

While their co-founder’ backgrounds certainly helped their initial growth, much of it has come from their innovative approach to marketing.

I recently spent a month reverse-engineering their funnel, from top to bottom. And in doing so, I found 14 killer marketing strategies you can use to get more engagement and higher conversions for your site. 

In this blog post, I’ll show you:

  • Why Casper reinvented the buying experience for their target market (and what you can learn from it)
  • How to create content for each stage of your funnel (even if you own an e-commerce store)
  • The best link building strategy I’ve ever seen (hint: it involves .edu sites)
  • A simple, but little-known way to “monopolize” your Google search ads
  • How to get customers to refer their friends to your brand (without needing to ask)

Let’s get started.

Part 1: Positioning

Positioning is everything.

It’s how you capture the biggest market share and become a household name. And, how you build your strategy around your competition’s weaknesses.

Here’s how Casper is winning the battle for their buyers’ minds…

Strategy #1: Reinvent The Buying Experience

Buying a mattress was once a complicated affair. 

First, you had to browse several furniture stores to compare prices. Then, you had to choose a type of mattress (open spring, pocket spring, etc.). More, you had to test its firmness depending on your preferred sleeping position, height, and weight. Next, you had to choose an appropriate size (single, double, king size, etc.). Finally, after making a decision, you had to negotiate with a pushy salesperson trying to upsell you. 

And that was just the beginning. 

Once bought, you had to guide the delivery man through your home, praying he wouldn’t damage your new mattress before setting it down.

Today, it’s a VERY different experience.

While buying a mattress in-store is still common, Casper has reinvented what it means to buy a mattress. 

Gone are the days of awkwardly lying on a mattress in front of a salesman and then waiting around all day for a delivery. 

Today, with a few clicks of a mouse, you can order a mattress from the comfort of your home and have it delivered for free within a 60-minute window of your choice. (Source)

Casper’s reinvention of the buying experience runs throughout their marketing, beginning top-of-funnel with their Google search ads.

Casper_s Google Search Ad

As Lindsay Kaplan, Casper’s VP of communications and brand engagement said in one interview:

Our strategy from the start has been to change perceptions about mattress shopping and create a community around sleep in a playful and creative way, with a genuine voice. (Source)

Casper has reinvented the buying experience by capitalizing on the “mattress in a box” concept, a trend that’s seen a steady climb in recent years, particularly in the United States and Canada (more on that shortly).

Mattress in a Box
Casper_s Interest by Region

Buying a mattress in a box is exactly as it sounds. Once it arrives, you remove the mattress from the box and set it on your foundation while it’s still encased in plastic. Then, you remove the mattress from its plastic wrapping, give it 45 minutes to an hour to regain its shape, and you’re ready for a good night’s sleep. 

Here it is in action:  

Similar to companies like Apple, Casper has transformed something as mundane as unboxing their product into a memorable, share-worthy experience. 

In fact, they even go as far as encouraging you to document your unboxing experience on their frequently asked questions (FAQ) page.

Casper_s FAQ Page

Unboxing, in and of itself, is another trend Casper has capitalized on, given its increased interest in recent years.

Unboxing in Google Trends

Casper’s unboxing videos are so popular, they have millions of views on YouTube, alone, resulting in free publicity for the company.

Casper Unboxing Video

It’s no surprise then that 53.86% of Casper’s entire social traffic comes from YouTube (most of which comes from their customer’s videos rather than their own.)

Casper_s Social Traffic

When you reinvent the buying experience. People pay attention.

Action Item: Ask yourself, “Can I reinvent the buying experience for my customers?” “Can I capitalize on a growing trend to help deliver that experience?” “Can I make every stage of the buying cycle memorable and share-worthy?”

Strategy #2: Create an Unbeatable Guarantee

Imagine, for a moment, you’re in a pet shop and your child is begging you for a puppy. 

Unsure whether it’s a good idea, you say no. 

The salesperson, aware of this dynamic, proposes the following: “Take the puppy home over the weekend. If it’s too much responsibility, bring it back on Monday for a full refund, no questions asked.”

Secretly hoping that your child will lose interest by the end of the weekend, you agree to take the puppy home. Most of the time, you turn out to be right. The child does lose interest in the puppy—but you fall in love with it. By Sunday night, you want the puppy more than the child does. Ding. Ding.

The puppy-dog close, as it’s known, is one of the most effective closing techniques in the book. And, unsurprisingly, one Casper leverage throughout their marketing, notably with their unbeatable guarantee.

For each of their mattresses, Casper offers a risk-free 100-night free trial.

Casper_s Guarantee

The promise? If you decide Casper’s mattress isn’t for you, they’ll send a courier over to remove it from your home and either donate it to a local charity or have it recycled. Best of all, you don’t even need to have the box.

Casper isn’t just focused on making money; they’re interested in helping those in need and doing their part for the environment. This resonates with millennials, especially, who consider charity and the environment key deciding factors in their purchasing decisions. (ht: Rikke.)

There’s also a secondary benefit to offering a 100-night free-trial. Casper knows that once a customer makes the product a part of their everyday life, whether they know it or not, they’re far less likely to return it.

As mentioned above, Casper’s 100-night free trial isn’t something casually mentioned as an afterthought (such as on their checkout page). Rather, it’s something that’s consistent through each stage of their funnel (especially in their cart recovery emails which we’ll discuss in Part 5: Strategy#1).

Action Item: You probably already have a guarantee for your products. But is it unbeatable? Is it one that your customers love you for (and your competitors hate you for)? If not, consider lowering the barrier to entry so that your offer is too good for prospects to ignore. 

Part 2: Content Marketing

Casper leverage three content archetypes as part of their strategy, each with the goal of nudging prospects further along the purchase funnel. 

As a refresher, here’s an example of a funnel, including examples of content archetypes at each stage:

Purchase Funnel

Source: Cartina

Let’s take a look.

Strategy #3: Answer Your Target Market’s Questions (To-Fu)

Casper’s blog, Pillow Talk, ranks on page one for many medium-tail keywords such as “can’t sleep” and “sleeping positions.” They also rank for more general, long-tail search queries like “what to do when you can’t sleep” and “how to go to sleep earlier.”

Casper_s Organic Keywords

Much of their To-Fu content is short-form and humorous, whereas others, as we’ll see in Part 3: Strategy #2, is well-researched.

Casper Content Example

Interestingly, rather than ask for an email address on these pages, Casper incentivize you to submit a survey about your sleeping habits, offering a $25 discount as a reward.

Casper Survey Popup

In it, they ask questions about your preferred sleeping position, your evening routine, as well as general demographic questions about your age, income, gender, and more:

Preferred Sleeping Position

At the end of the survey, they ask for your email, before offering you a coupon code. 

Casper_s Survey Confirmation Page

Casper even tracks how many visitors click “Shop Casper” after completing the survey to determine whether it’s a strategy worth continuing:

Promo Code Labs

And it’s clever, for three reasons:

  1. Answering their target buyer’s most pressing questions increases Casper’s organic footprint in the SERPs and positions them as a market authority.
  2. Surveying visitors that have come from specific search queries gives them a highly-targeted focus group and feedback so they can improve their marketing.
  3. Offering a discount, front-end, to a visitor who came from organic search fast-tracks impulse buyers without the need to pay for traffic (more on that in Part 4). 

Action Item: Using sites like Quora and Reddit, research your target market’s most pressing questions and create content that answers those questions. To learn more about how to do that, step-by-step, read this article.

Strategy #4: Create a Go-To Comparison Resource (MoFu)

A common obstacle to buying something, like a mattress, is not knowing which is right for you.

As mentioned above, there are lots of considerations such as the type of mattress, its size, its firmness, and more.  

Casper help potential buyers overcome confusion with their mattress size comparison guide

Casper_s Mattress Comparison Guide

While it isn’t very long, it does rank for hundreds of keywords in position #1, including several long-tail keywords like “king size bed dimensions” and “queen mattress dimensions.” 

Casper_s Positions in The SERPs

And, for keywords that it doesn’t rank position #1 for, it ranks for featured snippets (also known as Position #0). 

For example, for “queen size bed dimensions in feet,” they rank position #6 (at time of writing), but rank for a featured snippet, stealing 8.6% of all clicks in the process.

Queen Size Bed Dimensions in Feet

What’s interesting is, rather than ask you for feedback on this page, as they do for their To-Fu content, Casper invite you to enter a competition. 

It’s clever. A visitor who is comparing mattress sizes is likely further along the buyer’s journey than someone who is searching for sleeping aids. So, Casper asks for an email, rather than feedback, and introduce their products in their onboarding emails (more on that in Part 5).

Action Item: If you sell different types of product (e.g. cosmetics like foundation), create a comparison guide that helps buyers find the right one for them. Bonus if you can rank it well in the SERPs.

Strategy #5: Showcase All Reviews in One Place (BoFu)

You know the importance of using customer testimonials to help close potential buyers. But are you showcasing them as best as you can?

Knowing the importance of reviews in a competitive market, Casper showcases all their reviews on one page on their site.

First, they feature written reviews by their customers, including the person’s name, where they’re from, and how they rate Casper.

Casper_s Reviews

(Casper is 100% transparent here. If you click, “See all reviews,” you can read everything their customers say about them, including the unhappy ones.)

Beneath their customer reviews, you can read tweets from customers, adding further to the legitimacy of their reviews.

Casper Tweet Testimonial

Finally, Casper adds the third layering of social proof: media badges and press mentions.

Casper_s Media Mentions

There’s a reason why Casper go to such great lengths to optimize their review page and we’ll discuss why in Part 5: Strategy #2.

Action Item: It’s common for online stores to have their reviews on third-party sites. But that doesn’t always mean its a best practice. Take your best reviews and have them on one page on your site so you have more control over how you market your business. 

Part 3: Link Building

As of writing, Casper has 148k backlinks from 5.54 referring domains.

Casper_s Backlinks

It’s impressive, but unless you have a multi-million dollar marketing budget, few of their link building strategies are replicable (if you’re curious, I’ve included my three favorites in the bonus resource).

So, rather than explore the unreplicable, I want to show you three unconventional ways Casper build links and how you can, too. 

Strategy #6: Build White-Hat Education Links with “The CSD Method”

If you know anything about link building, you know getting .edu links are the best you can get. They pass a TON of Page Rank, but they’re also tough to acquire. Unless, of course, you have a unique angle…

Take a look at Casper’s referring domains.

If we refine the search, we can see they’ve built twelve do-follow .edu links using, what I call, the college student discount (CSD) strategy. 

Education Links to Casper

So, what is Casper doing to build these links? 

They’re inserting their product into the lives of a market that may benefit from it:


Take a look at this page from California State University, Northridge (CSUN):

Link from CSUN

On it, students can get discounts from a range of products and services including apparel, insurance—and mattresses.

Casper Discount Code

Coincidence? Maybe. But probably not.

Here’s another example from The State University of New York, again, with a page discounting products and services for students.

Link from SUNY

If you scroll down, they, too, have a discount on any Casper mattress.

Casper Discount Code 2

While it’s impossible to know if Casper actively sought out these links and others, it’s highly likely, given the frequency of these type of links—and the PageRank they pass. 

Action Item: It’s easy to assume building links like the above is impossible. But many sites, like CSUN, have a form where you can submit discounts of your own. Ask yourself, “Who else can I serve?” Then, consider where that target market hangs out and reach out to the right sites.

Strategy #7: Publish Original Research (and Become a Go-To Expert in Your Marketplace)

In Section #2, we discussed the three content archetypes Casper use to generate search traffic. You also learned one of those archetypes was content that answers your target market’s questions.

Casper does a fine job of doing that. But, sometimes, answering a question goes beyond giving an opinion. In truth, to become an authority on a subject, you often need to cite, or even better, publish original research. 

Take, for instance, Casper’s post, “How Often Should I Replace My Mattress?”

How Often Should I Replace My Mattress

In it, Casper debunks an industry myth about how often you should change your mattress. 

Rather than cite other people’s research, they use their own findings having researched their own mattresses, and set the record straight.

This page on their FAQ got a nice DR90 link from Healthline which just goes to show: 

Content doesn’t always have to be published on a blog for it to acquire links. 

Action Item: If you’re creating content for your site, consider publishing original research (even if it’s a meta-analysis of other studies) Yes, it takes time. But it can also be an asset for sites in your marketplace to link to.

Strategy #8: Use “The Best-of Backlink Builder” (with a Twist)

One of the quickest and easiest ways for online retailers to build links is to get featured in best-of content—content that curates the best of the best for a niche. (I call it “the best-of backlink builder”).

For example, Casper has built several high domain authority links by getting featured in “best [keyword] ideas” content, such as “best wedding gift ideas.”

In fact, Casper has acquired several do-follow links from several high-authority sites like The Knot (DR:90) and Brides (DR:82) using this very strategy. 

Link from Brides

Now, here’s where it takes an interesting turn.

Heavy, a news and information site, also feature Casper in a best-of article for “top bridal shower gift ideas.”

Top Bridal Shower Gift Ideas

But upon closer inspection, it’s actually an affiliate link.

Heavy Affiliate Link

While it’s highly unlikely a site like Casper reached out to get featured in an article like this, it is likely sites like Heavy are more willing to link to a product if there’s a chance to earn a commission on the backend. (So, if you don’t have an affiliate program for your products, it might be worth thinking about.)

The best part about getting featured in best-of content, of course, is it’s scalable. 

Using a tool like Ahrefs, you can enter a competitor’s domain, click “Referring Domains > Backlinks” to view the type of content they’re featured in. Then, you can go after similar sites. (To learn more about how to do a competitive analysis, read this in-depth guide.)  

Action Item: The Best-Of Backlink Builder is a killer strategy if you sell products that are good gift ideas. Using search operators like “best [keyword] gifts” and “[keyword] gifts for [gender],” identify sites that could include your offer. Then, reach out to them. Yes, it’s time-consuming. But it’s a great e-commerce link building strategy.

Part 4: Paid Acquisition 

Like many multi-million dollar companies, Casper invests a fortune in paid advertising.

In fact, as of writing, their estimated monthly budget for Google Adwords, alone, is $128,000. (Source: SimilarWeb).

Casper_s Paid Search

But that doesn’t mean their strategies can’t be modelled on a smaller scale.

Here are my three favorite strategies I found while researching.

Strategy #9: Translate Your Ads to Capture New Markets

A good marketer knows which countries are driving the most traffic to their site.

Casper is no exception.

Using a tool like SimilarWeb, we can see the majority of Casper’s traffic comes from the United States, the United Kingdom, Canada, France, and Germany. 

Casper_s Traffic by Countries

So, it makes sense that Casper advertises to users in the United States, the United Kingdom, and Canada in English. After all, for the US and the UK, (and 56.9% of Canada), English is the mother tongue. 

But what about countries like France and Germany where English isn’t the first language?

Casper is growing their market share in other countries by translating their ads into the target country’s first language.

Take, for instance, the following display ad, shown to German visitors who have previously visited Casper’s site.

Casper_s German Display Ad

When clicked, users are taken to a landing page with German copy and customer support.

Casper_s German Landing Page

If you try to leave, Casper shows a exit-intent popup asking for your email address.

Casper_s German Exit Intent Popup

In English it reads:

“We will soon make one of your dreams come true. Sign up and never ‘sleep over’ from news, products and discounts from Casper.”

This strategy works well for three reasons:

  1. Translating ad copy into a target market’s language personalizes your marketing. 
  2. Offering customer support helps readers overcome objections to buying (more on that in Strategy #12).
  3. Capturing abandoning visitors’ email addresses gives you an opportunity to remarket using another media (like email).  

Action Item: Log into Google Analytics and click, “Audience > Overview > Country” to identify your audience by country. Then, consider translating your ad copy into the mother tongue of one or more of those countries.


Strategy #10: Try This Little-Known Trick to Monopolize Your Search Ads

If you’re using Google search ads to grow your business, you know that you can’t have more than one search ad that sends visitors to the same site at the same time. 

But that hasn’t stopped Casper from monopolizing their most profitable keywords.

Take, for instance, “casper mattress reviews,” a search query we discussed before.

Here’s what I see when I Google that term. Notice anything interesting?

Casper_s Google Search Ads

Casper dominates three out of four of the ads, directing visitors to Amazon, Google reviews, and, of course, their site. They’re all online retailers which sell their products. Further, they have a Google Shopping ad to the right making it near impossible to ignore them.

Pretty clever, huh?

Action Item: This strategy is advanced. I’ll grant you that. But if you can pull it off, and your products are available on other sites, consider sending visitors to them beyond your own site.

Strategy #11: Combine Advertising and Remarketing to Get More Leads for Your Online Store

You’ve probably experimented with Facebook Advertising. 

And if you have, it’s likely you’ve experimented with remarketing using native advertising. 

But have you ever tried both simultaneously?

Casper has. In fact, it’s something they’re doing to win new customers.

Here’s how it works. 

First, Casper advertises their brand to new audiences using a Facebook Ad.

Casper Facebook Ad

In it, they entice users to click-through using a curiosity gap (“What is the social unboxing phenomenon, and why is it taking over the Internet?”).

From there, Casper sends users to a CBS article praising their brand’s positioning. 

How a Mattress Company Gains an Online Following

Now, you might be wondering, “What’s the point in driving traffic to a third-party site with no call-to-action, aside from building social proof?”

If you are, I pondered that, too.

That is until I scrolled to the bottom of the page…

Casper_s Native Ad

Because I had already visited their site, particularly their product page, Casper retargeted me using a Criteo ad. In fact, I knew it wasn’t random because the tracking code was visible in the URL:

Casper Retargeting

Mind. Blown.

Action Item: Look for a site that (a) praises your brand and (b) allows ads or sponsored links on their site. Then, experiment with driving traffic from Facebook to that site and track the number of referrals through their site’s ads.

Part 5: Email Marketing

Like many online retailers, Casper sends a variety of marketing emails. 

Here, I’ll focus on three specific email strategies they’re using to move prospects through their funnel.

Let’s move on.

Strategy #12: Use This 2-Step Cart Abandonment Process to Recover Lost Sales

Casper leverage a clever 2-step cart abandonment process for recovering on-the-fence buyers. 

When I abandoned my cart, I received the first of two cart recovery emails a day later. 

Casper_s Cart Recovery Email

In it, Casper invited me to complete my purchase. Nothing new there. But beneath the call-to-action, was a GIF, highlighting frequently asked questions, and an invite to get in touch if I had any questions.

Casper_s Cart Recovery Email 2

Inviting abandoning visitors to reach out isn’t just an example of great customer service, it’s also a great way to overcoming potential objections that weren’t addressed on a prospect’s first visit. Further, Casper give several ways to get in touch, making it as easy as possible for you have your questions answered and complete your order.

I chose not to return to my cart. So, a day later, I got a second email. 

Casper Recovery Email 2

In it, Casper emphasize the unbeatable guarantee we saw in Strategy #1, making it as easy as possible for me to complete my purchase.

Casper Guarantee

What’s most interesting about Casper, is their ability to recognize their unfair advantages—like their 100-night free trial—and use it throughout each stage of their marketing. And therein lays an important takeaway:

You might not be able to compete with your competitor when it comes to free shipping, 3-month guarantees and other expectations consumers have. But, you can take what makes your business unique, and remind prospects again and again. 

Action Item: If you own an online store and send cart recovery emails, give prospective buyers an opportunity to contact you. Then, help them overcome any objections they have so they can move forward with their purchase.

Strategy #13: Turn Customers into Salespeople with This Replicable Referral Engine

If you read my post on Harry’s Marketing, you know Harry’s got 100,000 email addresses in seven days—before they made a single sale.

Casper has built a similar referral engine into their marketing, post-purchase, inviting customers to refer friends.

Here’s how it works.

After buying from Casper, you get an order confirmation email. Nothing new there. But here’s where it gets interesting…

In the email footer, there’s a referral link to refer friends and earn rewards.

Casper_s Referral Program in Email Footer

Source: Really Good Emails

This creates a curiosity gap. The rewards aren’t specified, so you’re enticed to click-through and learn more.

When you click “Learn More,” you’re redirected to a page on Casper’s site where you’re offered an Amazon gift card in exchange for each referral you make. 

The best part?

They make sharing super simple, depending on your preferred media.

Casper Referral Code

For instance, if you click “Email,” Casper trigger a prewritten email so you don’t even have to write the message yourself.

Casper_s Prewritten Email

It saves you time, and it’s a great way to simplify leaving a review.

Action Item: Your customers are your greatest salespeople. So, invite them to refer others—and incentivize them for doing so. You might not be able to refer Amazon Gift Cards (few can), but you can offer them something (e.g. a discount on a future purchase).

Strategy #14: Get Better Customer Reviews with This Simple, Yet Powerful Copy Hack

As mentioned above, Casper uses their order confirmation emails to invite new customers to refer friends.

But that hasn’t always been their strategy…

In the beginning, while building their authority in their marketplace, Casper built their reputation through asking for reviews.

Here’s how it worked:

A few days after becoming a new customer, Casper would invite you to leave a review on their site.

Casper_s Review Email

After clicking the call-to-action, you would have been redirected to Casper’s review page. On it, Casper would have invited you to leave feedback using several questions as prompts.

Casper_s Review Submission Form

Casper knows consumers tend to write generic reviews when asked, so, back then, they guided customers to write about areas important to them (Casper). This included the unboxing experience and whether the customers would recommend Casper to a friend.

And it worked.

Casper has hundreds of reviews that meet all of the above.

Casper Review

Today, Casper repurpose these reviews in the marketing, particularly in their onboarding emails. Here’s the fourth email you receive after signing up for updates from Casper:

Review in Email

No amount of copy you write will ever outperform praise from a customer. So, use glaring reviews in your emails. And use them often.

Action Item: Invite new customers to review their purchase after enough time passes. Then, guide them on what to say, based on potential objections to buying your product or areas you want to highlight. Finally, repurpose those reviews throughout your marketing.   



So, there you have it: the best of Casper’s marketing in under 5,000 words.
