Offline promotion methods for mini-programs (QR codes, Wi-Fi)

QR Code Promotion

QR codes are one of the core tools for offline promotion of mini-programs, allowing users to directly jump to the mini-program page after scanning. Common types of QR codes include standard QR codes, mini-program codes, and sun codes. Mini-program codes are exclusive QR codes provided by WeChat, offering higher recognition rates and security.

Example of Generation Method:

// Generate a mini-program code using the WeChat official API  
wx.cloud.callFunction({  
  name: 'getWXACode',  
  data: {  
    path: 'pages/index/index',  
    width: 430  
  },  
  success(res) {  
    console.log(res.result)  
  }  
})  

Application Scenarios:

1. Store Displays: Posting at checkout counters, product shelves, etc.
2. Promotional Materials: Printed materials like posters, flyers, and banners.
3. Product Packaging: Outer packaging of goods such as food and daily necessities.
4. Event Venues: On-site setups at exhibitions, conferences, etc.

Optimization Tips:

• Add guiding text: "Scan the QR code to experience now."
• Design aesthetically pleasing QR code styles.
• Test scanning effectiveness at different sizes.
• Monitor scan data and optimize placement.

Wi-Fi Promotion

Wi-Fi connectivity is another important channel for mini-programs to acquire offline users. By embedding mini-program entry points on Wi-Fi authentication pages, targeted user acquisition can be achieved.

Technical Implementation Example:

// Example of calling the WeChat Wi-Fi API  
wx.startWifi({  
  success() {  
    wx.connectWifi({  
      SSID: 'StoreWiFi',  
      password: '12345678',  
      success() {  
        // Redirect to the mini-program after successful connection  
        wx.navigateToMiniProgram({  
          appId: 'target_mini_program_appid',  
          path: 'pages/welcome'  
        })  
      }  
    })  
  }  
})  

Implementation Steps:

1. Apply for the WeChat Wi-Fi feature.
2. Configure router authentication methods.
3. Design the authentication page UI.
4. Set up redirection logic and data analysis.

Typical Application Scenarios:

• Dining Establishments: Recommend membership mini-programs after scanning to connect to Wi-Fi.
• Hotels: Push service mini-programs when connecting to the network.
• Shopping Malls: Guide users to mall mini-programs via free Wi-Fi.
• Transportation Hubs: Recommend travel service mini-programs at stations and airports.

Combined Promotion Strategy

Combining QR codes and Wi-Fi promotion can create synergistic effects. For example, in a café scenario:

1. Display a mini-program ordering QR code on table stickers.
2. Show a membership discount page after connecting to the store's Wi-Fi.
3. Place a "scan to pay for instant discounts" prompt at the checkout counter.

Data Tracking Implementation:

// Record the promotion channel source  
wx.getLaunchOptionsSync({  
  success(res) {  
    const scene = res.scene  
    if(scene === 1044) { // QR code scenario value  
      analytics.track('from_qrcode')  
    } else if(scene === 1089) { // Wi-Fi scenario value  
      analytics.track('from_wifi')  
    }  
  }  
})  

Performance Evaluation Metrics

Establishing a comprehensive evaluation system is crucial for measuring promotion effectiveness:

1. Scan-to-Conversion Rate: Scans / Impressions
2. New User Ratio: Proportion of new users acquired through the channel.
3. Retention Rate: 7-day / 30-day retention data.
4. ROI: Calculation of return on investment.

Data Analysis Code Snippet:

// Report promotion performance data  
function reportPromotionData(channel) {  
  wx.request({  
    url: 'https://api.example.com/track',  
    data: {  
      channel,  
      openid: wx.getStorageSync('openid'),  
      timestamp: Date.now()  
    }  
  })  
}  

Common Issues and Solutions

QR Code Scan Failure Handling:

1. Check if the QR code has expired.
2. Verify if the linked page path is correct.
3. Test recognition rates under different lighting conditions.
4. Provide fallback options (e.g., searching for the mini-program name).

Wi-Fi Connection Troubleshooting:

1. Check the router's WeChat Wi-Fi configuration.
2. Validate the portal page loading speed.
3. Test compatibility across different device models.
4. Monitor connection success rate metrics.

Real-World Optimization Case:
A supermarket chain improved conversion rates through the following adjustments:

• Moved QR codes from pillars to shopping cart handles.
• Added countdown prompts on Wi-Fi authentication pages.
• Automatically issued new-user coupons after scanning.
• Analyzed data differences across stores weekly.
