WordPress-Level Preparation

+

This plugin can prepare your WordPress site for SXG, but cannot implement the full SXG infrastructure.

+ +
+ +

Add SXG-compatible headers and meta tags (WordPress level only)

+
+ + +
+ + +
+ +
+ + + +
+

Environment Testing

+

Test if your server environment can run amppackager binary before proceeding with setup.

+ +
+ + +
+
+ + + + + + + +
+

Setting Up Full SXG Support

+
+
+
1. Server Requirements
+
    +
  • Linux server with root access (not shared hosting)
    • +
  • Go runtime environment installed
    • +
  • Ability to configure web server (Apache/Nginx)
    • +
  • SSL certificate from supported CA
    • +
+
+ +
+
2. Install amppackager
+
+ 
# Download and install amppackager
+wget https://github.com/ampproject/amppackager/releases/download/latest/amppackager
+chmod +x amppackager
+sudo mv amppackager /usr/local/bin/
+
+# Create config directory
+sudo mkdir -p /etc/amppackager
+
+
+ +
+
3. Configure Web Server
+

Configure your web server to:

+
    +
  • Vary responses on Accept and AMP-Cache-Transform headers
    • +
  • Proxy SXG requests to amppackager
    • +
  • Serve different content for the same URL based on headers
    • +
+
+ +
+
4. Maintenance
+
    +
  • Update amppackager every 6 weeks
    • +
  • Monitor certificate expiration
    • +
  • Ensure persistent storage for amppackager instances
    • +
+
+
+
+ + +
