6 experiments in this playbook — here are the highest-impact tests to start with. Each is a ready-to-run recipe with a hypothesis and a target metric.

Estimated lift ranges are typical results across comparable D2C stores — your numbers depend on traffic, vertical, and baseline.

Why it works

Built on patterns proven across thousands of D2C stores.

Most stores are designed on desktop and lose money on mobile. This playbook fixes the small-screen experience — reachable buttons, shorter scrolls, and wallet-first checkout — where the majority of your traffic actually shops.

  • Mobile drives most D2C sessions but usually converts well below desktop.
  • A sticky ATC bar matters most on mobile, where the buy button scrolls away fastest.
  • Express wallets remove keyboard friction — the biggest mobile-checkout killer.
  • Single-column, collapsed layouts shorten the scroll that loses mobile buyers.

The complete guide

Understanding the Mobile-First Playbook

The Mobile-First Playbook addresses the biggest blind spot in most D2C stores: a site designed and reviewed on desktop while the majority of customers shop on a phone. The result is a mobile conversion rate well below desktop — and a large, recoverable revenue gap.

The plays target the realities of the small screen: reachability (sticky add-to-cart and thumb-sized tap targets), scroll length (collapsed accordions and single-column layouts), and checkout friction (express wallets surfaced first so shoppers never type on a phone).

Each test is built and previewed mobile-first in CustomFit without code, targets mobile sessions specifically, and reports mobile conversion lift — so you optimize for where your traffic actually is.

Can I run a test on mobile only?

Yes. CustomFit targets device type, so every play in this playbook can be scoped to mobile sessions while desktop stays untouched.

How many experiments are in this playbook?

All 6 experiments in this playbook are detailed on this page, in priority order — start at the top and work down.

Do I need a developer to run this playbook?

No. Every experiment recreates as a no-code experience in the CustomFit visual editor; developers can use the API and SDKs when they want deeper control.

How quickly can I get started?

Most teams install CustomFit in minutes via a single script tag or the Shopify app and ship the first test in this playbook the same week.
