How Social Media Sharing Actually Works ?

#html #marketing #socialmedia #webdev

When you paste a URL on Facebook, Twitter, or LinkedIn, here's what happens behind the scenes:
1️⃣ The Crawl - Platform sends a bot to your URL
2️⃣ HTML Parsing - Scans your page for meta tags
3️⃣ Content Extraction - Pulls title, description, image
4️⃣ Preview Generation - Creates the rich preview card
5️⃣ Caching - Stores the data for future shares

🖼️ Image Requirements (Critical!):
• Size: Minimum 1200x630px (Facebook), 1024x512px (Twitter)
• Format: JPG, PNG, WebP
• File Size: Under 8MB
• Accessibility: Must be publicly accessible via HTTPS
• Alt Text: Include og:image:alt for accessibility

📝 Content Best Practices:
• Title: 60-90 characters (gets truncated after)
• Description: 150-160 characters for optimal display
• Image: High contrast, readable text, brand consistent
• URL: Clean, descriptive URLs perform better
