Mobile conversions are notoriously lower than desktop ones. And if you’ve hit a plateau and are struggling to increase conversion rate, don’t give up!

Time4Sleep is an e-commerce company that was in that very position just two years ago—but they eventually increased mobile conversions by 63% for one of their biggest product categories.

How did they do it? By tossing so-called ‘best practices’ aside and obsessing over their users.

Introducing Time4Sleep

Time4Sleep is an online retailer that sells high-quality beds and mattresses at deeply discounted prices, and they faced the same issue that most online businesses do—getting mobile traffic to convert.

Since 70% of their traffic comes from mobile devices, they had an urgent issue on their hands.


They used a blend of tools like heatmaps, website feedback, and session recordings along with Google Analytics to develop and test hypotheses about what kept visitors from converting. Then they made changes and ran A/B tests to see whether those changes boosted conversions.

In the end, they increased conversion rates across their entire business, which included a 63% increase (!) in mobile conversions.

Refusing to blindly follow ‘best practices’

Many companies try to increase conversions by blindly implementing best practices they’ve read about online.

The trouble with best practices is that they’re always based on another company’s experience. In other words, what works for Amazon may not (and probably won’t) work for everyone else. Also, best practice is by definition ‘past’ practice—something that worked well enough twelve months ago and made it to the list of best practices is possibly no longer as effective right now.

Relying on best practices was not the right way forward. Time4Sleep’s customers are unique, as are its products and business model—so they needed to go back to the core issues and needs that people had when visiting Time4sleep, and use insight from their research to optimize mobile conversion rates.

The hypothesis: giving customers easier access to buying guides might boost conversions

Based on user persona research, Time4Sleep had reason to believe that first-time buyers had no idea how to actually buy a bed. These people likely didn’t understand the difference between sizes or styles, and there were gaps in what they needed to know to make an informed, confident decision.


They hypothesized that the breakthrough in the buyer’s journey would come by helping visitors access this information. Time4Sleep featured plenty of buying guides on their website—but did people actually see them?

Mobile CRO example: 5 steps to understanding what prevents mobile visitors from converting

Before spending time, effort, and money on final website changes, good CRO requires you to develop and test your hypotheses. Here are the steps Time4Sleep took to understand the problem and come up with a data-driven action plan.

Step 1: Review your analytics data

Web analytics tools show traffic data in aggregate, including which pages users visit more often, where the traffic came from, and where people left the site. They went to Google Analytics to observe the big picture and look for red flags.


In particular, during their investigation, they used special queries to see how many visitors jumped from the category page (beds) to specific product pages (e.g., a specific bed) and then back to the category page. This is what they discovered: the cycle often repeated endlessly until visitors logged off (without buying).

Step 2: Watch session recordings to see how customers behave

Session recordings show a replay of anonymous individual user sessions. They looked for visitors who bounced back and forth between product pages (e.g., a page with a product description for a specific bed) and relevant category pages (e.g., the parent page for beds).

They saw people aimlessly wandering from page to page without making a purchase.

Step 3: Study heatmaps to check on-page interaction

Heatmaps show where visitors click in aggregate (the ‘hotter’ the spot, the more clicks a button receives) and how far they scroll down a page. Heatmaps helped to see which fields mobile visitors paid attention to and how far down the pages they scrolled.


Heatmaps confirmed the suspicion: the links to Time4Sleep’s buyer guides, which answer common product questions, weren’t getting much use.

Step 4: Use on-page surveys/polls to gather user feedback

Armed with that knowledge, they decided to collect user feedback to ask visitors about their experiences. They asked questions such as:

  • “Is there anything preventing you from purchasing at this point?”
  • “Is our pricing clear?”
  • “Is there anything on this page that doesn’t work the way you expected it to?”
  • “If you could change anything about this page, what would it be?”


The results confirmed that many visitors (including those who had already placed items in their shopping cart) were confused about bed-buying fundamentals.

Bringing all the user research together

After taking all the steps above, the team identified the following barriers to conversion:

  • Visitors would go as far as the checkout page (with a product in their cart), but they still lacked the information they needed to complete the purchase
  • Visitors would endlessly jump back and forth between the ‘bed’ (category) page and individual product pages without converting
  • Visitors rarely clicked on links to buying guides because the links were buried under existing content
  • Visitors rarely clicked on buttons that allowed them to sort through products (by highest price, lowest price, what’s on sale, etc.) because it wasn’t obvious what the buttons did

Making (and testing) the changes

Based on the insights gained from the research, the team of developers, designers, and content writers worked together to make and test significant changes.

What did they actually look like? For example, they edited the main ‘bed’ product category page to include:

  • Visible links to information pages at the top of the page
  • Better, more usable filters that were simplified for mobile visitors
  • Improved informational content




The result: a 63% boost in mobile conversions

After testing three different variations, the winner produced a 63% increase in mobile conversion rates for the bed shopper segment.

Keep in mind, 70% of Time4Sleep’s traffic comes from mobile visitors, so a 63% conversion rate on mobile traffic is a huge win.

Additional wins

They produced some amazing results for mobile conversions, but that wasn’t the only thing they improved.

Time4Sleep experienced the following improvements for the ‘Beds’ category page:

  • 19% global increase in overall conversions
  • 36% more visitors have reached the cart
  • 124% more visitors reached informational content (bed size guides, children’s bed guides, etc.)
  • 9% reduction in bounce rate from the category pages


The heatmap on the left shows the old mobile category page. People tended to scroll really deep down the page, but this was not a good thing: prospective customers were scrolling not because they enjoyed the content, but because they could not find what they were looking for. With the new solution, most people could easily identify what they needed at the top of the page instead.

Conclusion (4 tips to increase your mobile conversion rates)

Ready to increase your mobile conversion rates with data-driven changes? Here are some tips based on Time4Sleep’s experience.

1: Reject so-called ‘best practices’

Your company, products/services, and user experience should be carefully tailored to your own visitors, not someone else’s. What works for another company might not work for you, and best practices can lead you astray.

2: Use web analytics to get a top-level understanding of what’s happening

Which pages do your users visit in aggregate? Where do they seem to drop off? All this information can provide clues about what’s going on… and you can use those clues to form a hypothesis (which you’ll then test).

3: Use behavior and feedback tools to understand the context

Use a combination of heatmaps, session recordings, and on-page surveys to observe how people interact with page elements and browse through your site, and to ask for direct feedback whenever you have a question or doubt that needs answering.

4: Make changes and test them out

The data you collected should help you come up with a clear hypothesis of what needs fixing. If you have enough traffic to do so, A/B test your variations to see if your changes increase conversion rates. Keep the changes that yield the best results, and use what you learned to form a new hypothesis to continue improving.

Time4Sleep made mobile conversions skyrocket—and you can, too!

PS. Even though it’s gaining popularity the concept of mobile-first is still more a concept than reality. Still, most businesses design the website for desktop first and then adapt it to mobile. It should be the other way around. Or, better yet, if you have enough traffic, these could be two very different websites and experiences.
