The app promotion fundamentals for eCommerce apps
Before investing in large-scale app promotion campaigns, including paid media, influencer activations, or launch bursts, it’s critical to have the fundamentals in place.
Promoting your app is not about a single launch moment. It’s about systematically embedding the app into the marketing channels you already own to create continuous visibility, relevance, and a clear reason for users to switch to the app.
Visibility alone doesn’t drive adoption. Users install and keep apps because they understand what’s in it for them: faster experiences, exclusive benefits, convenience, personalisation, or features that simply work better than the mobile web.
Crucially, every touchpoint should answer one simple user question:
“Why should I use the app instead of the website or other channels?”
That answer can take many forms:
Faster checkout or easier reordering
Exclusive app-only offers or early access
Better personalisation and recommendations
Order tracking, saved preferences, or loyalty benefits
A smoother, more intuitive mobile experience
The activities in this article are intentionally focused on existing channels you already own — your app listing, website and email. These channels are already live and already generate traffic; these fundamentals are low effort and low cost to implement, but have a high impact on adoption.
The checklist
App Store - Strong app listing
App Store - (5-star) ratings and reviews
Website - Smart app banner on the mobile website
Website - Small persistent website banner
Website - App Store icons & Links in website footer
Website - Dedicated app landing page (with QR Code)
Email - App Store Icons in marketing email footers
Email - Order & transactional Emails
App Store
Your App Store listing is not just about visibility; it is an important conversion moment. Even when users already know your brand, they validate their decision before installing. The description, screenshots, ratings and reviews support that decision.
Brands like Nike, Zalando, and GAP clearly highlight convenience, exclusivity, personalisation, and loyalty benefits — not just interface visuals.
Strong app listing
The core elements of an app listing are the description, keywords and the screenshots.
To create a strong app listing, focus on clearly communicating your unique value proposition in the first lines, use high-intent keywords and create screenshots that match the description and value proposition. For example: “Faster Checkout” or “App-Only Offers”.
Note that (only) the first three screenshots are visible in the app overview. Make sure that these screenshots cover the core value proposition.
Why it matters and best practices
Strong listings improve organic ranking in the App Store
Better conversion lowers the Cost Per Install (CPI) from paid campaigns
Tip: Make the value proposition explicit in the description and screenshots
Tip: Select high-intent keywords from your website analytics
Tip: Create screenshots that show benefits, not (just) features
(5-star) ratings and reviews
Users install apps they trust and consider high-quality. A 4.8★ rating with recent positive reviews builds confidence. A lower rating or outdated feedback creates friction and doubt. In competitive categories, ratings and reviews are often the final decision factor.
Use your soft-launch phase to collect feedback, reviews and ratings. Ask proactively to rate and review the app.
Why it matters and best practices
Higher ratings (ideally 4.5★+) significantly increase install rates
Social proof builds instant trust
Gather ratings with structured in-app review prompts after positive moments.
Continuously monitor reviews (and ratings) and respond proactively
Website
Your website is your highest-intent acquisition channel. The goal is to inform your visitors about the app and create a series of easy touchpoints, but not to interrupt.
Examples:
BeautySolutions (JMango360 customer); implemented all website elements below
Smart app banner (mobile website)
A banner shown on the mobile website (only) prompting visitors to download or open the app.. Note that Apple automatically shows their default Smart app banner on Safari; this is linked to your Apple Developer account.
Why it matters and best practices
The majority of traffic in eCommerce is mobile (> 50%)
With strong execution, smart banners can generate 0.7–1% of total mobile traffic as installs, making it one of the highest-ROI owned acquisition channels.
Best practice – highlight a clear benefit e.g., “Track orders faster in the app”
Small persistent website banner
A subtle banner promoting the app on desktop and mobile without interrupting browsing.
Why it matters and best practices
Lower bounce rate versus pop-ups
Create continuous visibility
Best practices: Link to the App Stores (via a OneLink) or to a landing page about the app.
Best practice: highlight a clear benefit or social proof, e.g., “Download our app for exclusive discounts and the latest drops” or “Download our 4.8 ⭐ rated app”.
App store icons and links in website footer
Permanent App Store and Google Play links, visible across all pages on desktop and mobile.
Why it matters and best practices
Always-on, low-effort acquisition
Best practices: Link to the App Stores
Dedicated app landing page (including QR code)
A landing page explaining the app’s value, with App Store links and a QR code.
Why it matters and best practices
On this page you can explains why to use the app and the value proposition. Improving install conversion and strengthens trust.
Use the QR code to bridge dektop to mobile
Use your app listing for content and add social proof including ratings and reviews.
Email communication
- Zalando: App icons consistently present in newsletter footers
- Amazon: “Track your order in the app” module
App store links in marketing email footers (newsletter)
Why it matters and best practices
Always-on, low-effort acquisition
Best practices: Link to the App Stores
App store links + app promotion in transactional emails
Transactional emails are often one of the lowest-cost, highest-quality app acquisition channels for eCommerce brands.
Why it matters and best practices
Always-on, low-effort acquisition
Transactional emails are highly effective for app acquisition because they combine very high open rates (70–90%) with a moment of peak engagement.
Customers have just completed a purchase, are in a positive mindset, and are actively paying attention. This makes app messaging feel helpful rather than promotional.
Positioned the app as a convenience benefit e.g., order tracking or faster reordering.
