Part 1: Structured Data Implementation

✅ Add Schema.org Markup

Goal: Give AI models machine-readable facts instead of forcing them to guess.

Priority Schema Types:

  • Article Schema - For blog posts and news

    • ``json

    {

    "@context": "https://schema.org",

    "@type": "Article",

    "headline": "Your Article Title",

    "author": {

    "@type": "Person",

    "name": "Author Name"

    },

    "datePublished": "2025-12-30",

    "publisher": {

    "@type": "Organization",

    "name": "Your Company"

    }

    }

    `

  • FAQPage Schema - For FAQ sections

    • `json

    {

    "@context": "https://schema.org",

    "@type": "FAQPage",

    "mainEntity": [{

    "@type": "Question",

    "name": "What is your product?",

    "acceptedAnswer": {

    "@type": "Answer",

    "text": "Clear, concise answer here (40-60 words)"

    }

    }]

    }

    `

  • Product Schema - For product pages

    • `json

    {

    "@context": "https://schema.org",

    "@type": "Product",

    "name": "Product Name",

    "description": "Product description",

    "offers": {

    "@type": "Offer",

    "price": "99.00",

    "priceCurrency": "USD"

    }

    }

    `

  • Organization Schema - For homepage/about page

    • `json

    {

    "@context": "https://schema.org",

    "@type": "Organization",

    "name": "Your Company",

    "url": "https://yoursite.com",

    "logo": "https://yoursite.com/logo.png",

    "description": "What your company does"

    }

    `
