One lazy Sunday evening, I decided to order Thai delivery for dinner. It was a Green-Curry-and-Crispy-Wonton kind of night.
A quick google search from my iPhone turned up an ad for a food delivery app. In that moment, I wanted to order food fast, without having to dial a phone number or speak to a human. So, I clicked.
From the ad, I was taken to the company’s mobile website. There was a call-to-action to “Get the App” below the fold, but I didn’t want to download a whole app for this one meal. I would just order from the mobile site.
Dun, dun, duuuun.
Over the next minute, I had one of the most frustrating ordering experiences of my life. Labeless hamburger menus, the inability to edit my order, and an overall lack of guidance through the ordering process led me to believe I would never be able to adjust my order from ‘Chicken Green Curry’ to ‘Prawn Green Curry’.
After 60 seconds of struggling, I gave up, utterly defeated.
I know this wasn’t a life-altering tragedy, but it sure was an awful mobile experience. And I bet you have had a similar experience in the last 24 hours.
Let’s think about this for a minute:
- This company paid good money for my click
- I was ready to order online: I was their customer to lose
- I struggled for about 30 seconds longer than most mobile users would have
- I gave up and got a mediocre burrito from the Mexican place across the street.
Not only was I frustrated, but I didn’t get my tasty Thai. The experience left a truly bitter taste in my mouth.
Why is mobile website optimization important?
In 2017, every marketer ‘knows’ the importance of the mobile shopping experience. Americans spend more time on mobile devices than any other. But we are still failing to meet our users where they are on mobile.
For most of us, it is becoming more and more important to provide a seamless mobile experience. But here’s where it gets a little tricky…
“Conversion optimization”, and the term “optimization” in general, often imply improving conversion rates. But a seamless mobile experience does not necessarily mean a high-converting mobile experience. It means one that meets your user’s needs and propels them along the buyer journey.
I am sure there are improvements you can test on your mobile experience that will lift your mobile conversion rates, but you shouldn’t hyper-focus on a single metric. Instead, keep in mind that mobile may just be a step within your user’s journey to purchase.
So, let’s get started! First, I’ll delve into your user’s mobile mindset, and look at how to optimize your mobile experience. For real.
What’s different about mobile?
First things first: let’s acknowledge that your user is the same human being whether they are shopping on a mobile device, a desktop computer, a laptop, or in-store. Agreed?
So, what’s different about mobile? Well, back in 2013, Chris Goward said, “Mobile is a state of being, a context, a verb, not a device. When your users are on mobile, they are in a different context, a different environment, with different needs.”
Your user is the same person when she is shopping on her iPhone, but she is in a different context. She may be in a store comparing product reviews on her phone, or she may be on the go looking for a good cup of coffee, or she may be trying to order Thai delivery from her couch.
This is why many mobile optimization experts recommend having a mobile website versus using responsive design.
Responsive design is not an optimization strategy. We should stop treating mobile visitors as ‘mini-desktop visitors’. People don’t use mobile devices instead of desktop devices, they use it in addition to desktop in a whole different way.– Talia Wolf, Founder & Chief Optimizer at GetUplift
(If you don’t have a clear picture of your target customer, you should re-focus and tackle that question first.)
Step two is to understand how your user’s mobile context affects their existing motivation, and how to facilitate their needs on mobile to the best of your ability.
Understanding the mobile context
To understand the mobile context, let’s start with some stats and work backwards.
- Americans spend more than half (54%) of their online time on mobile devices (Source: KPCB, 2016)
- Mobile accounts for 60% of time spent shopping online, but only 16% of all retail dollars spent (Source: ComScore, 2015)
Insight: Americans are spending more than half of their online time on their mobile devices, but there is a huge gap between time spent ‘shopping’ online, and actually buying.
- 29% of smartphone users will immediately switch to another site or app if the original site doesn’t satisfy their needs (Source: Google, 2015)
- Of those, 70% switch because of lagging load times and 67% switch because it takes too many steps to purchase or get desired information (Source: Google, 2015)
Insight: Mobile users are hypersensitive to slow load times, and too many obstacles.
So, why the heck are our expectations for immediate gratification so high on mobile? I have a few theories.
Mobile devices provide constant access to the internet, which means a constant expectation for reward.
“The fact that we don’t know what we’ll find when we check our email, or visit our favorite social site, creates excitement and anticipation. This leads to a small burst of pleasure chemicals in our brains, which drives us to use our phones more and more.” – TIME, “You asked: Am I addicted to my phone?”
If non-stop access has us primed to expect non-stop reward, is it possible that having a negative mobile experience is even more detrimental to our motivation than a negative experience in another context?
When you tap into your Facebook app and see three new notifications, you get a burst of pleasure. And you do this over, and over, and over again.
So, when you tap into your Chrome browser and land on a mobile website that is difficult to navigate, it makes sense that you would be extra annoyed. (No burst of fun reward chemicals!)
A mobile device is a personal device
Another facet to mobile that we rarely discuss is the fact that mobile devices are personal devices. Because our smartphones and wearables are with us almost constantly, they often feel very intimate.
In fact, our smartphones are almost like another limb. According to research from dscout, the average cellphone user touches his or her phone 2,167 times per day. Our thumbprints are built into them, for goodness’ sake.
Just think about your instinctive reaction when someone grabs your phone and starts scrolling through your pictures…
It is possible, then, that our expectations are higher on mobile because the device itself feels like an extension of us. Any experience you have on mobile should speak to your personal situation. And if the experience is cumbersome or difficult, it may feel particularly dissonant because it’s happening on your mobile device.
User expectations on mobile are extremely high. And while you can argue that mobile apps are doing a great job of meeting those expectations, the mobile web is failing.
If yours is one of the millions of organizations without a mobile app, your mobile website has got to work harder. Because a negative experience with your brand on mobile may have a stronger effect than you can anticipate.
Even if you have a mobile app, you should recognize that not everyone is going to use it. You can’t completely disregard your mobile website. (As illustrated by my extremely negative experience trying to order food.)
You need to think about how to meet your users where they are in the buyer journey on your mobile website:
- What are your users actually doing on mobile?
- Are they just seeking information before purchasing from a computer?
- Are they seeking information on your mobile site while in your actual store?
The great thing about optimization is that you can test to pick off low-hanging fruit, while you are investigating more impactful questions like those above. For instance, while you are gathering data about how your users are using your mobile site, you can test usability improvements.
Usability on mobile websites
If you are looking to get a few quick wins to prove the importance of a mobile optimization program, usability is a good place to begin.
The mobile web presents unique usability challenges for marketers. And given your users’ ridiculously high expectations, your mobile experience must address these challenges.
Below are four of the core mobile limitations, along with recommendations from the WiderFunnel Strategy team around how to address (and test) them.
Note: For this section, I relied heavily on research from the Nielsen Norman Group. For more details, click here.
1. The small screen struggle
No surprise, here. Compared to desktop and laptop screens, even the biggest smartphone screen is smaller―which means they display less content.
“The content displayed above the fold on a 30-inch monitor requires 5 screenfuls on a small 4-inch screen. Thus mobile users must (1) incur a higher interaction cost in order to access the same amount of information; (2) rely on their short-term memory to refer to information that is not visible on the screen.” – Nielsen Norman Group, “Mobile User Experience: Limitations and Strengths”
Consider persistent navigation and calls-to-action. Because of the smaller screen size, your users often need to do a lot of scrolling. If your navigation and main call-to-action aren’t persistent, you are asking your users to scroll down for information, and scroll back up for relevant links.
Note: Anything persistent takes up screen space as well. Make sure to test this idea before implementing it to make sure you aren’t stealing too much focus from other important elements on your page.
2. The touchy touchscreen
Two main issues with the touchscreen (an almost universal trait of today’s mobile devices) are typing and target size.
Typing on a soft keyboard, like the one on your user’s iPhone, requires them to constantly divide their attention between what they are typing, and the keypad area. Not to mention the small keypad and crowded keys…
Target size refers to a clickable target, which needs to be a lot larger on a touchscreen than it is does when your user has a mouse.
So, you need to make space for larger targets (bigger call-to-action buttons) on a smaller screen.
Test increasing the size of your clickable elements. Google provides recommendations for target sizing:
You should ensure that the most important tap targets on your site—the ones users will be using the most often—are large enough to be easy to press, at least 48 CSS pixels tall/wide (assuming you have configured your viewport properly).
Less frequently-used links can be smaller, but should still have spacing between them and other links, so that a 10mm finger pad would not accidentally press both links at once.
You may also want to test improving the clarity around what is clickable and what isn’t. This can be achieved through styling, and is important for reducing ‘exploratory clicking’.
When a user has to click an element to 1) determine whether or not it is clickable, and 2) determine where it will lead, this eats away at their finite motivation.
Another simple tweak: Test your call-to-action placement. Does it match with the motion range of a user’s thumb?
3. Mobile shopping experience, interrupted
As the term mobile implies, mobile devices are portable. And because we can use ‘em in many settings, we are more likely to be interrupted.
“As a result, attention on mobile is often fragmented and sessions on mobile devices are short. In fact, the average session duration is 72 seconds […] versus the average desktop session of 150 seconds.” – Nielsen Norman Group
You should design your mobile experience for interruptions, prioritize essential information, and simplify tasks and interactions. This goes back to meeting your users where they are within the buyer journey.
According to research by SessionM (published in 2015), 90% of smartphone users surveyed used their phones while shopping in a physical store to 1) compare product prices, 2) look up product information, and 3) check product reviews online.
You should test adjusting your page length and messaging hierarchy to facilitate your user’s main goals. This may be browsing and information-seeking versus purchasing.
4. One window at a time
As I’m writing this post, I have 11 tabs open in Google Chrome, split between two screens. If I click on a link that takes me to a new website or page, it’s no big deal.
But on mobile, your user is most likely viewing one window at a time. They can’t split their screen to look at two windows simultaneously, so you shouldn’t ask them to. Mobile tasks should be easy to complete in one app or on one website.
The more your user has to jump from page to page, the more they have to rely on their memory. This increases cognitive load, and decreases the likelihood that they will complete an action.
Your navigation should be easy to find and it should contain links to your most relevant and important content. This way, if your user has to travel to a new page to access specific content, they can find their way back to other important pages quickly and easily.
In e-commerce, we often see people “pogo-sticking”—jumping from one page to another continuously—because they feel that they need to navigate to another page to confirm that the information they have provided is correct.
A great solution is to ensure that your users can view key information that they may want to confirm (prices / products / address) on any page. This way, they won’t have to jump around your website and remember these key pieces of information.
Implementing mobile website optimization
As I’m sure you’ve noticed by now, the phrase “you should test” is peppered throughout this post. Because understanding the mobile context, and reviewing usability challenges and recommendations are first steps.
If you can, you should test any recommendation made in this post. Which brings us to mobile website optimization. At WiderFunnel, we approach mobile optimization just like we would desktop optimization: with process.
You should evaluate and prioritize mobile web optimization in the context of all of your marketing. If you can achieve greater Return on Investment by optimizing your desktop experience (or another element of your marketing), you should start there.
But assuming your mobile website ranks high within your priorities, you should start examining it from your user’s perspective. The WiderFunnel team uses the LIFT Model framework to identify problem areas.
The LIFT Model allows us to identify barriers to conversion, using the six factors of Value Proposition, Clarity, Relevance, Anxiety, Distraction, and Urgency. For more on the LIFT Model, check out this blog post.
A LIFT illustration
I asked the WiderFunnel Strategy team to do a LIFT analysis of the food delivery website that gave me so much grief that Sunday night. Here are some of the potential barriers they identified on the checkout page alone:
- Relevance: There is valuable page real estate dedicated to changing the language, when a smartphone will likely detect your language on its own.
- Anxiety: There are only 3 options available in the navigation: Log In, Sign Up, and Help. None of these are helpful when a user is trying to navigate between key pages.
- Clarity: Placing the call-to-action at the top of the page creates disjointed eyeflow. The user must scan the page from top to bottom to ensure their order is correct.
- Clarity: The “Order Now” call-to-action and “Allergy & dietary information links” are very close together. Users may accidentally tap one, when they want to tap the other.
- Anxiety: There is no confirmation of the delivery address.
- Anxiety: There is no way to edit an order within the checkout. A user has to delete items, return to the menu and add new items.
- Clarity: Font size is very small making the content difficult to read.
- Clarity: The “Cash” and “Card” icons have no context. Is a user supposed to select one, or are these just the payment options available?
- Distraction: The dropdown menus in the footer include many links that might distract a user from completing their order.
Needless to say, my frustrations were confirmed. The WiderFunnel team ran into the same obstacles I had run into, and identified dozens of barriers that I hadn’t.
But what does this mean for you?
When you are first analyzing your mobile experience, you should try to step into your user’s shoes and actually use your experience. Give your team a task and a goal, and walk through the experience using a framework like LIFT. This will allow you to identify usability issues within your user’s mobile context.
Every LIFT point is a potential test idea that you can feed into your optimization program.
Case study examples
This wouldn’t be a WiderFunnel blog post without some case study examples.
This is where we put ‘best mobile practices’ to the test. Because the smallest usability tweak may make perfect sense to you, and be off-putting to your users.
In the following three examples, we put our recommendations to the test.
Mobile navigation optimization
In mobile design in particular, we tend to assume our users understand ‘universal’ symbols.
But, that isn’t always the case. And it is certainly worth testing to understand how you can make the navigation experience (often a huge pain point on mobile) easier.
You can’t just expect your users to know things. You have to make it as clear as possible. The more you ask your user to guess, the more frustrated they will become.– Dennis Pavlina, Optimization Strategist, WiderFunnel
This example comes from an e-commerce client that sells artwork. In this experiment, we tested two variations against the original.
In the first, we increased font and icon size within the navigation and menu drop-down. This was a usability update meant to address the small, difficult to navigate menu. Remember the conversation about target size? We wanted to tackle the low-hanging fruit first.
With variation B, we dug a little deeper into the behavior of this client’s specific users.
Qualitative Hotjar recordings had shown that users were trying to navigate the mobile website using the homepage as a homebase. But this site actually has a powerful search functionality, and it is much easier to navigate using search. Of course, the search option was buried in the hamburger menu…
So, in the second variation (built on variation A), we removed Search from the menu and added it right into the main Nav.
Both variations beat the control. Variation A led to a 2.7% increase in transactions, and a 2.4% increase in revenue. Variation B decreased clicks to the menu icon by -24%, increased transactions by 8.1%, and lifted revenue by 9.5%.
Never underestimate the power of helping your users find their way on mobile. But be wary! Search worked for this client’s users, but it is not always the answer, particularly if what you are selling is complex, and your users need more guidance through the funnel.
Mobile product page optimization
Let’s look at another e-commerce example. This client is a large sporting goods store, and this experiment focused on their product detail pages.
On the original page, our Strategists noted a worst mobile practice: The buttons were small and arranged closely together, making them difficult to click.
There were also several optimization blunders:
- Two calls-to-action were given equal prominence: “Find in store” and “+ Add to cart”
- “Add to wishlist” was also competing with “Add to cart”
- Social icons were placed near the call-to-action, which could be distracting
We had evidence from an experiment on desktop that removing these distractions, and focusing on a single call-to-action, would increase transactions. (In that experiment, we saw transactions increase by 6.56%).
So, we tested addressing these issues in two variations.
In the first, we de-prioritized competing calls-to-action, and increased the ‘Size’ and ‘Qty’ fields. In the second, we wanted to address usability issues, making the color options, size options, and quantity field bigger and easier to click.
Both of our variations lost to the Control. I know what you’re thinking…what?!
Let’s dig deeper.
Looking at the numbers, users responded in the way we expected, with significant increases to the actions we wanted, and a significant reduction in the ones we did not.
Visits to “Reviews”, “Size”, “Quantity”, “Add to Cart” and the Cart page all increased. Visits to “Find in Store” decreased.
And yet, although the variations were more successful at moving users through to the next step, there was not a matching increase in motivation to actually complete a transaction.
It is hard to say for sure why this result happened without follow-up testing. However, it is possible that this client’s users have different intentions on mobile: Browsing and seeking product information vs. actually buying. Removing the “Find in Store” CTA may have caused anxiety.
This example brings us back to the mobile context. If an experiment wins within a desktop experience, this certainly doesn’t guarantee it will win on mobile.
I was shopping for shoes the other day, and was actually browsing the store’s mobile site while I was standing in the store. I was looking for product reviews. In that scenario, I was information-seeking on my phone, with every intention to buy…just not from my phone.
Are you paying attention to how your unique users use your mobile experience? It may be worthwhile to take the emphasis off of ‘increasing conversions on mobile’ in favor of researching user behavior on mobile, and providing your users with the mobile experience that best suits their needs.
Note: When you get a test result that contradicts usability best practices, it is important that you look carefully at your experiment design and secondary metrics. In this case, we have a potential theory, but would not recommend any large-scale changes without re-validating the result.
Mobile checkout optimization
This experiment was focused on one WiderFunnel client’s mobile checkout page. It was an insight-driving experiment, meaning the focus was on gathering insights about user behavior rather than on increasing conversion rates or revenue.
Evidence from this client’s business context suggested that users on mobile may prefer alternative payment methods, like Apple Pay and Google Wallet, to the standard credit card and PayPal options.
To make things even more interesting, this client wanted to determine the desire for alternative payment methods before implementing them.
The hypothesis: By adding alternative payment methods to the checkout page in an unobtrusive way, we can determine by the percent of clicks which new payment methods are most sought after by users.
We tested two variations against the Control.
In variation A, we pulled the credit card fields and call-to-action higher on the page, and added four alternative payment methods just below the CTA: PayPal, Apple Pay, Amazon Payments, and Google Wallet.
If a user clicked on one of the four alternative payment methods, they would see a message:
“Google Wallet coming soon!
We apologize for any inconvenience. Please choose an available deposit method.
Credit Card | PayPal”
In variation B, we flipped the order. We featured the alternative payment methods above the credit card fields. The focus was on increasing engagement with the payment options to gain better insights about user preference.
Note: For this experiment, iOS devices did not display the Google Wallet option, and Android devices did not display Apple Pay.
On iOS devices, Apple Pay received 18% of clicks, and Amazon Pay received 12%. On Android devices, Google Wallet received 17% of clicks, and Amazon Pay also received 17%.
The client can use these insights to build the best experience for mobile users, offering Apple Pay and Google Wallet as alternative payment methods rather than PayPal or Amazon Pay.
Unexpectedly, both variations also increased transactions! Variation A led to an 11.3% increase in transactions, and variation B led to an 8.5% increase.
Because your user’s motivation is already limited on mobile, you should try to create an experience with the fewest possible steps.
You can ask someone to grab their wallet, decipher their credit card number, expiration date, and ccv code, and type it all into a small form field. Or, you can test leveraging the digital payment options that may already be integrated with their mobile devices.
The future of mobile website optimization
Imagine you are in your favorite outdoor goods store, and you are ready to buy a new tent.
You are standing in front of piles of tents: 2-person, 3-person, 4-person tents; 3-season and extreme-weather tents; affordable and pricey tents; light-weight and heavier tents…
You pull out your smartphone, and navigate to the store’s mobile website. You are looking for more in-depth product descriptions and user reviews to help you make your decision.
A few seconds later, a store employee asks if they can help you out. They seem to know exactly what you are searching for, and they help you choose the right tent for your needs within minutes.
Imagine that while you were browsing products on your phone, that store employee received a notification that you are 1) in the store, 2) looking at product descriptions for tent A and tent B, and 3) standing by the tents.
Mobile optimization in the modern era is not about increasing conversions on your mobile website. It is about providing a seamless user experience. In the scenario above, the in-store experience and the mobile experience are inter-connected. One informs the other. And a transaction happens because of each touch point.
Mobile experiences cannot live in a vacuum. Today’s buyer switches seamlessly between devices [and] your optimization efforts must reflect that.– Yonny Zafrani, Mobile Product Manager, Dynamic Yield
We wear the internet on our wrists. We communicate via chat bots and messaging apps. We spend our leisure time on our phones: streaming, gaming, reading, sharing.
And while I’m not encouraging you to shift your optimization efforts entirely to mobile, you must consider the role mobile plays in your customers’ lives. The online experience is mobile. And your mobile experience should be an intentional step within the buyer journey.
