MobiLoud Smart App Banner

Driving traffic to your app from your mobile site is the smartest way to gain new app users and retain mobile visitors. To get these people to down load your app, you can use smart app banners.

We highly recommend promoting your app using smart app banners – with these you’ll show a banner suggesting to install your app only to your website visitors using either an iOS or an Android device.

Read on to learn more about smart banners, and how to implement a smart app banner on your site.

What Are Smart App Banners?

'Smart App Banners' are banners that show up when someone lands on your mobile website, prompting them to get your app.

Here's an example:

Here's what Apple's own help pages say about smart app banners:

"Smart App Banners vastly improve users’ browsing experience compared to other promotional methods. Users will trust that tapping the banner will take them to the App Store and not a third-party advertisement. They will appreciate that banners are presented unobtrusively at the top of a webpage, instead of as a full-screen ad interrupting the web content. And with a large and prominent close button, a banner is easy for users to dismiss. When the user returns to the webpage, the banner won’t reappear."

• Banner can be used as a module or used directly in an html / script tag
• Code written in Typescript and minified/bundled with Vite

📖 How to use

Smart Banner can be used importing the JS code via CDN or as a module using NPM

🚀 With CDN

<script type="module" src="https://cdn.jsdelivr.net/npm/@mobiloud/ml-smart-banner/dist/ml-smart-banner.min.js"></script>
<script>
  function addSmartBanner() {
    new SmartBanner().init();
  }
  window.addEventListener('load', addSmartBanner);
</script>

Configuration options:

const options = {
    fontFamily: `"Source Sans Pro", "Arial", sans-serif`, // (string) Font family for banner texts, defaults to system safe fonts
    fallbackFontFamily: 'sans-serif', // (string) Font family for fallback icon, safe options are serif and sans-serif
    appName: 'ML', // (string) Initials for fallback icon.  Recommended 2 characters. Fallback Image uses button text and bg color
    textColor: '#222', // (string) Banner texts color (any color property value)

    iconUrl: '', // (string) Icon url, defaults to avatar with appName
    textHeading: 'Download now!', // (string) Heading Text
    textDescription: 'Try it now, download today', // (string) Description text
    bannerColor: '#fff', // (string) Banner BG color
    linkIos: 'https://itunes.apple.com/', // (string) Link for iOS 
    linkAndroid: 'https://play.google.com/', // (string) Link for Android 
    position: 'bottom', // (string) Position of the banner, default 'top'. 'top' | 'bottom'
    animation: 'fadeIn', // (string) Banner animation, default 'fadeIn'. 'fadeIn' | 'scaleUp' | 'slideBottom' | 'slideTop' | 'slideLeft' | 'slideRight' | null,
    display: 'onLoad', // (string) Display options, default 'onLoad'. 'onLoad' | 'onScrollDown' | 'onScrollUp'
    radius: '0', // (string) Banner radius with units
    delay: 0, // (number) defines how much time to wait until the element shows up
    shadow: true, // (boolean) If true applies soft shadow, true | false
    useSession: true, // (boolean) If true, after closed, Banner is not shown upon page reload. Default: true
    zindex: 999999 // (number) Sets the z-index of the element
}

const smartBanner = new SmartBanner(options);

Methods

deviceData.os // returns current os "android" | "ios" | "windows" | "desktop"
deviceData.isCanvas // returns true or false
deviceData.isMobile // returns true or false

Recipes

This are useful ways to implement the widget. We always recommend using an Event Listener to trigger the code when the document is loaded window.addEventListener('load', fnName)

Insert QR Banner on desktop only

function addSmartBanner() {
	if(deviceData.isMobile || deviceData.isCanvas ){
		return
	}
    new SmartBanner(options).init();
  }
  window.addEventListener('load', addSmartBanner);

Using deviceData method to filter devices

const options = {
  // Set params here
}

// Insert widgets only in our Canvas platform
if(deviceData.isCanvas) {
const smartBanner = new SmartBanner(options);
}

// Apply specific configs based on OS
if(deviceData.os === "android" || deviceData.os === "windows") {
  const smartBanner = new SmartBanner(options1);
} 
if(deviceData.os === "desktop" || deviceData.os === "ios") {
  const smartBanner = new SmartBanner(options2);
}

// Insert widgets only in Mobile userAgent
if(deviceData.isMobile) {
const smartBanner = new SmartBanner(options3);
}

Events

The library emits some useful events in the browser window, these can be used to trigger custom functions using event listeners.

• BANNER_CLOSED: Triggered when close button is clicked, banner gets unmounted from page also.
• BANNER_MOUNTED: Triggered when banner is mounted in page, on init() it gets unmounted as a cleanup and then mounted.
• BANNER_UNMOUNTED: Triggered when banner is mounted in unmounted, this is triggered on close or when firing unmount(),
• BANNER_LINK_CLICKED: Triggered when banner link is clicked

Triggering events based on Smart Banner events

window.addEventListener('BANNER_MOUNTED', () => {
  console.log('banner opened');
  // trigger something...
});
window.addEventListener('BANNER_CLOSED', () => {
  console.log('banner closed');
  // trigger something...
});
window.addEventListener('BANNER_UNMOUNTED', () => {
  console.log('banner unmounted');
  // trigger something...
});
window.addEventListener('BANNER_LINK_CLICKED', () => {
  console.log('banner link clicked');
  // trigger something...
});

Development

• npm run build produces a production version into /dist folder
• npm run dev runs dev version and starts a dev server

Testing the smart app banner

You will definitely want to test the smart app banners once you deploy them to your website, to make sure that everything works and looks as you want.

Running these tests on real mobile devices can get overwhelming, so we recommend that you run your tests on your desktop browser.

To do this, you will need to emulate a mobile device by adjusting your browser’s user agent. We recommend using the following Chrome extension to do this: User Agent Switcher and Manager

Once you have installed the extension, set it up as follows:

Step 1

Select “Chrome” as the browser and “Android” as the platform if you want to test the Android version of the banner, or “Safari” and “iOS” in case you want to test the iOS version:

Step 2

Select one of the options that will appear, any will work:

Step 3

Click “Apply” to make sure the user agent is properly set up on your browser:

Step 4

You can now press “F5” while viewing your website to refresh the browser window with the updated user agent.

Reset

If you want to revert the changes to the user agent, as some websites might start behaving differently after doing so, you can click the “Reset” button:
