Common Mistakes to Avoid
❌ Don't Do This:
- Multiple placements - Choose head OR body, not both
- External files - Google may not crawl .json files
- Invalid JSON - Always validate your code
- Dynamic injection delays - Ensure early execution
- Missing type attribute - Always include type="application/ld+json"
🎯 Quick Decision Guide
Use <head> when:
- ✅ You have access to HTML head
- ✅ Using WordPress, Shopify, etc.
- ✅ Maximum performance needed
- ✅ Following Google's recommendations
Use <body> when:
- ⚠️ CMS restricts head access
- ⚠️ Generating content dynamically
- ⚠️ Using specific frameworks
- ⚠️ Above-the-fold content requirements
Advanced: Dynamic JSON-LD Placement
// For Single Page Applications (SPA)
function injectJSONLD(schema) {
const script = document.createElement('script');
script.type = 'application/ld+json';
script.text = JSON.stringify(schema);
document.head.appendChild(script);
}
// Usage
injectJSONLD({
"@context": "https://schema.org",
"@type": "Article",
"headline": "Dynamic Content"
});
// For optimal performance, inject as early as possible

Generate JSON-LD CodeFrequently Asked Questions
Can I put JSON-LD in both head and body?
No, avoid this. While technically possible, it can cause duplicate content issues and confuse search engines. Choose one location.
What if my CMS doesn't allow head access?
Use body placement. Place the JSON-LD as high as possible in the <body> section, ideally right after the opening <body> tag.
Does placement affect Core Web Vitals?
Minimal impact when done correctly. JSON-LD in <head> doesn't block rendering. Large scripts in <body> can affect LCP.
How many JSON-LD blocks can I have per page?
Multiple blocks are fine. You can have separate JSON-LD blocks for different schema types (Organization, Article, Breadcrumb, etc.).
