70% of your traffic. 40% less revenue.

Pull up your analytics real quick. I'll wait.

Look at the split between mobile and desktop traffic. For most DTC brands we work with, it's somewhere around 65-75% mobile.

Now look at conversion rate by device.

Hurts, doesn't it?

Mobile conversion rates are consistently 40-60% lower than desktop. And before you say "people are just browsing on their phones", no. They're not. They're trying to buy. Your checkout is just making it too hard.

I've run 200+ mobile-specific tests over the past three years. The same three problems show up over and over. Fix these and you'll see meaningful RPV lifts. Ignore them and you're basically paying to drive traffic to an experience designed to lose sales.

Friction Point #1: The form field gauntlet

Picture this. Your customer has already decided to buy. They're committed. They tap "Checkout."

And then they're staring at 15-20 form fields on a 6-inch screen.

Name. Email. Address line 1. Address line 2. City. State. Zip. Phone. Card number. Expiration. CVV. Billing address... wait, is it the same as shipping?

Each field is a micro-decision. Each one is a moment where they can fat-finger something, get frustrated, or think "I'll do this on my laptop later."

(Later, tomorrow, never.)

What works:

• Auto-detection everywhere. Google Places API for address auto-complete. Detect card type from the first digits. Auto-populate city and state from zip code. Every field you can fill automatically is a field that can't cause friction.

• Correct input types. I still see this constantly, email fields that don't trigger the @ keyboard. Phone fields that show a full QWERTY keyboard. Zip code fields that don't show the numeric pad. Every wrong keyboard is a 1 second delay multiplied by millions of sessions.

• Collapse what you can. Billing same as shipping? Default to yes and hide those fields. Guest checkout should be the default, not a tiny link below "Create Account."

Friction Point #2: The trust gap at payment

Here's something counterintuitive. The moment a customer is closest to converting is the moment they're most likely to bail.

The payment step has the highest abandonment rate of any checkout stage on mobile. Why?

Because entering your credit card on a phone feels risky. The screen is small. You can't see the full URL. The lock icon is tiny. You're probably on public WiFi. The entire context screams "don't enter your card here."

What works:

• Express payment options above the fold. Apple Pay. Google Pay. Shop Pay. These aren't just faster, they're trusted. The customer authenticates with their fingerprint or face through a system they already trust.

• Security signals at the payment step. Not buried in the footer. A small lock icon with "256-bit encrypted" next to the card field. Trust badges near the payment button. These matter more on mobile because the screen provides fewer ambient trust signals.

• Don't redirect to third-party payment pages. Every redirect on mobile is a potential drop-off. That URL change registers, consciously or not, as "something sketchy." Embedded payment forms convert better.

Friction Point #3: The surprise at the end

This one drives me crazy because it's so preventable.

Customer has added to cart. Entered their info. Entered their payment. And then the order summary shows a shipping cost they didn't expect. Or a tax amount that pushes the total past their mental threshold. Or a delivery estimate that says 10-14 business days.

Cart abandonment at the final step is almost always a surprise problem, not a price problem.

People don't mind paying $8 for shipping. (OK, they do, but they'll accept it.) What they can't stand is finding out about $8 shipping after they've invested 3 minutes in checkout.

What works:

• Show estimated totals early. In the cart. On the product page if possible. "Free shipping over $Y, you're $Z away." Set the expectation before checkout begins.

• Shipping calculator in the cart. Let people enter their zip code and see options before they start checkout. This filters out the people who were going to abandon anyway and lets committed buyers proceed with full information.

• Delivery dates, not ranges. "Arrives by March 4" converts better than "Ships in 5-7 business days." People process dates faster than math. A Baymard Institute study found that 24% of users misinterpret delivery speed labels. Give them the actual date.

• Sticky order summary on mobile. As the customer scrolls through checkout, keep a collapsible summary visible. They should see their total at any point without scrolling back up.

The compounding effect

Here's what makes mobile checkout optimization so powerful. These friction points compound.

A customer who struggles with form fields, then feels uncertain about payment, then gets surprised by shipping, that's three small frictions that add up to one abandoned cart.

But it works the other way too. Smooth forms build momentum. Trusted payment builds confidence. No surprises build satisfaction. Each fix makes the next step easier.

We typically see 4-8% RPV lifts from comprehensive mobile checkout optimization. On a $30M brand, that's $1.2M-$2.4M in incremental annual revenue. From fixing an experience that most of your customers are already trying to use.

The traffic is there. The intent is there. You just need to stop getting in the way.

Want us to audit your mobile checkout and find the friction that's costing you revenue? That's kind of our thing.

Every brand in this newsletter saw results from fixing what was already broken, not from buying more traffic. We're taking on two new clients in April. If you want revenue that sticks around after you stop writing checks to Meta, we should talk.

Looking forward,

Brian
