Open Graph & Twitter Card Meta Tags: Referensi Lengkap

When you share a link on Facebook, Twitter, LinkedIn, Discord, or Slack, the rich preview card that appears is powered by Open Graph (OG) meta tags and Twitter Card tags. Getting these right means more clicks, more engagement, and a more professional appearance. Getting them wrong means broken previews, missing images, and lost traffic. This complete reference covers every tag, every platform requirement, and every common mistake — with copy-paste code for all major frameworks.

Essential Open Graph Tags

Open Graph protocol was created by Facebook in 2010 and has since been adopted by nearly every social platform. These four tags are the absolute minimum for any page:

og:title

The title of your page as it should appear in the social share card. Keep it under 60 characters for best display. This can differ from your HTML <title> tag — use it to craft a more compelling social headline.

<meta property="og:title" content="How to Build a REST API with Node.js in 2026" />

og:description

A brief summary of the page content shown below the title in the preview card. Aim for 120-160 characters. This is your chance to hook the reader into clicking.

<meta property="og:description" content="Step-by-step guide to building a production-ready REST API with Node.js, Express, and TypeScript. Includes auth, validation, and deployment." />

og:image

The image displayed in the social share card. This is the single most impactful tag — posts with images get 2-3x more engagement. Must be an absolute URL (not relative).

<meta property="og:image" content="https://example.com/images/rest-api-guide-og.png" />
<meta property="og:image:width" content="1200" />
<meta property="og:image:height" content="630" />
<meta property="og:image:alt" content="REST API with Node.js — Complete Guide" />
<meta property="og:image:type" content="image/png" />

og:url

The canonical URL of the page. This tells platforms which URL to associate with the shared content, preventing duplicate shares of the same content from different URLs.

<meta property="og:url" content="https://example.com/blog/rest-api-nodejs" />

og:type

The type of content. Common values: website (default), article (blog posts), product, video.movie, music.song, profile.

<!-- For a general page -->
<meta property="og:type" content="website" />

<!-- For a blog post / article -->
<meta property="og:type" content="article" />
<meta property="article:published_time" content="2026-02-10T08:00:00Z" />
<meta property="article:author" content="https://example.com/about" />
<meta property="article:section" content="Technology" />
<meta property="article:tag" content="Node.js" />
<meta property="article:tag" content="REST API" />

Additional Open Graph Tags

Beyond the basics, these tags give you finer control over how your content appears:

<!-- Site name — shown above the title on Facebook -->
<meta property="og:site_name" content="DevToolBox" />

<!-- Locale — language_TERRITORY format -->
<meta property="og:locale" content="en_US" />
<meta property="og:locale:alternate" content="fr_FR" />
<meta property="og:locale:alternate" content="de_DE" />
<meta property="og:locale:alternate" content="es_ES" />
<meta property="og:locale:alternate" content="ja_JP" />

<!-- Video (for og:type = video.*) -->
<meta property="og:video" content="https://example.com/video.mp4" />
<meta property="og:video:width" content="1280" />
<meta property="og:video:height" content="720" />
<meta property="og:video:type" content="video/mp4" />

<!-- Audio -->
<meta property="og:audio" content="https://example.com/podcast-ep1.mp3" />
<meta property="og:audio:type" content="audio/mpeg" />

Twitter Card Tags

Twitter (now X) supports its own card system with four card types. Twitter will fall back to Open Graph tags if Twitter-specific tags are missing, but dedicated tags give you full control.

Twitter Card Types

<!-- Summary Card (small image) -->
<meta name="twitter:card" content="summary" />
<meta name="twitter:site" content="@yourusername" />
<meta name="twitter:creator" content="@authorname" />
<meta name="twitter:title" content="How to Build a REST API with Node.js" />
<meta name="twitter:description" content="Complete guide with auth, validation, and deployment." />
<meta name="twitter:image" content="https://example.com/images/rest-api-square.png" />
<meta name="twitter:image:alt" content="REST API Guide illustration" />

<!-- Summary Card with Large Image -->
<meta name="twitter:card" content="summary_large_image" />
<meta name="twitter:site" content="@yourusername" />
<meta name="twitter:title" content="How to Build a REST API with Node.js" />
<meta name="twitter:description" content="Complete guide with auth, validation, and deployment." />
<meta name="twitter:image" content="https://example.com/images/rest-api-wide.png" />

<!-- Player Card (video/audio) -->
<meta name="twitter:card" content="player" />
<meta name="twitter:player" content="https://example.com/embed/video123" />
<meta name="twitter:player:width" content="1280" />
<meta name="twitter:player:height" content="720" />

<!-- App Card -->
<meta name="twitter:card" content="app" />
<meta name="twitter:app:id:iphone" content="123456789" />
<meta name="twitter:app:id:googleplay" content="com.example.app" />
<meta name="twitter:app:name:iphone" content="My App" />
<meta name="twitter:app:name:googleplay" content="My App" />

Image Requirements by Platform

Every platform has different image size requirements. Using the wrong dimensions results in cropped, stretched, or missing images. Here is the definitive reference:

Framework-Specific Examples

Modern frameworks provide built-in APIs for managing meta tags. Here is how to implement OG and Twitter Card tags in the most popular frameworks:

Next.js (App Router — Metadata API)

// app/blog/[slug]/page.tsx
import { Metadata } from 'next';

type Props = { params: { slug: string } };

export async function generateMetadata({ params }: Props): Promise<Metadata> {
  const post = await getPost(params.slug);

  return {
    title: post.title,
    description: post.excerpt,
    alternates: {
      canonical: `https://example.com/blog/${params.slug}`,
    },
    openGraph: {
      type: 'article',
      title: post.title,
      description: post.excerpt,
      url: `https://example.com/blog/${params.slug}`,
      siteName: 'My Dev Blog',
      locale: 'en_US',
      images: [
        {
          url: post.ogImage,      // Must be absolute URL
          width: 1200,
          height: 630,
          alt: post.title,
        },
      ],
      publishedTime: post.date,
      authors: [post.author],
      tags: post.tags,
    },
    twitter: {
      card: 'summary_large_image',
      site: '@yourusername',
      creator: '@authorname',
      title: post.title,
      description: post.excerpt,
      images: [
        {
          url: post.twitterImage,  // Can differ from OG image
          alt: post.title,
        },
      ],
    },
  };
}

export default function BlogPost({ params }: Props) {
  // Page component...
}

Nuxt 3 (useSeoMeta)

<!-- pages/blog/[slug].vue -->
<script setup lang="ts">
const route = useRoute();
const { data: post } = await useFetch(`/api/posts/${route.params.slug}`);

useSeoMeta({
  title: post.value.title,
  description: post.value.excerpt,
  ogType: 'article',
  ogTitle: post.value.title,
  ogDescription: post.value.excerpt,
  ogUrl: `https://example.com/blog/${route.params.slug}`,
  ogImage: post.value.ogImage,
  ogImageWidth: 1200,
  ogImageHeight: 630,
  ogImageAlt: post.value.title,
  ogSiteName: 'My Dev Blog',
  ogLocale: 'en_US',
  articlePublishedTime: post.value.date,
  articleAuthor: post.value.author,
  articleTag: post.value.tags,
  twitterCard: 'summary_large_image',
  twitterSite: '@yourusername',
  twitterCreator: '@authorname',
  twitterTitle: post.value.title,
  twitterDescription: post.value.excerpt,
  twitterImage: post.value.twitterImage,
  twitterImageAlt: post.value.title,
});
</script>

<template>
  <article>
    <!-- Page content -->
  </article>
</template>

Static HTML / Vanilla

<!-- For static HTML sites, simply add meta tags in <head> -->
<!-- You can automate this with a build tool or templating engine -->

<!-- Example with Eleventy (11ty) Nunjucks template -->
<head>
  <title>{{ title }}</title>
  <meta name="description" content="{{ description }}" />
  <meta property="og:type" content="{% if layout == 'post' %}article{% else %}website{% endif %}" />
  <meta property="og:title" content="{{ title }}" />
  <meta property="og:description" content="{{ description }}" />
  <meta property="og:image" content="{{ site.url }}{{ ogImage }}" />
  <meta property="og:url" content="{{ site.url }}{{ page.url }}" />
  <meta name="twitter:card" content="summary_large_image" />
  <meta name="twitter:title" content="{{ title }}" />
  <meta name="twitter:description" content="{{ description }}" />
  <meta name="twitter:image" content="{{ site.url }}{{ ogImage }}" />
</head>

<!-- Example with Hugo -->
<!-- layouts/partials/head.html -->
<meta property="og:title" content="{{ .Title }}" />
<meta property="og:description" content="{{ .Description }}" />
<meta property="og:image" content="{{ .Params.ogImage | absURL }}" />
<meta property="og:url" content="{{ .Permalink }}" />
<meta property="og:type" content="{{ if .IsPage }}article{{ else }}website{{ end }}" />
<meta name="twitter:card" content="summary_large_image" />
<meta name="twitter:title" content="{{ .Title }}" />
<meta name="twitter:image" content="{{ .Params.ogImage | absURL }}" />

Common Mistakes & How to Fix Them

These are the most frequent issues developers encounter with social meta tags. Each one can break your share previews:

Testing & Debugging Tools

Always validate your meta tags before publishing. Each platform caches previews aggressively, so fixing tags after sharing means waiting for cache expiration or manually clearing it.

Dynamic OG Images

Generating unique social images per page dramatically increases click-through rates. Instead of one generic image for your entire site, each page gets a custom card showing its title, description, or data.

Why Dynamic OG Images Matter

Sites like GitHub, Vercel, and DEV.to generate per-page OG images. The result: their links stand out in social feeds because every share looks unique and professional.

<!-- Instead of this (same image for every page): -->
<meta property="og:image" content="https://example.com/default-og.png" />

<!-- Generate this (unique per page): -->
<meta property="og:image" content="https://example.com/api/og?title=How+to+Build+a+REST+API" />

Generating with @vercel/og

// app/api/og/route.tsx — Next.js Edge Route Handler
import { ImageResponse } from 'next/og';
import { NextRequest } from 'next/server';

export const runtime = 'edge';

export async function GET(req: NextRequest) {
  const { searchParams } = new URL(req.url);
  const title = searchParams.get('title') || 'Default Title';
  const description = searchParams.get('desc') || '';

  return new ImageResponse(
    (
      <div
        style={{
          width: '100%',
          height: '100%',
          display: 'flex',
          flexDirection: 'column',
          justifyContent: 'center',
          padding: '60px 80px',
          background: 'linear-gradient(135deg, #0f172a 0%, #1e293b 100%)',
          fontFamily: 'Inter, sans-serif',
        }}
      >
        <div style={{
          fontSize: 56,
          fontWeight: 800,
          color: '#f8fafc',
          lineHeight: 1.2,
          marginBottom: 20,
        }}>
          {title}
        </div>
        {description && (
          <div style={{
            fontSize: 24,
            color: '#94a3b8',
            lineHeight: 1.5,
          }}>
            {description}
          </div>
        )}
        <div style={{
          display: 'flex',
          alignItems: 'center',
          marginTop: 'auto',
          fontSize: 20,
          color: '#64748b',
        }}>
          example.com
        </div>
      </div>
    ),
    {
      width: 1200,
      height: 630,
    }
  );
}

// Usage in metadata:
// openGraph: { images: [`/api/og?title=${encodeURIComponent(post.title)}`] }

Generating with Node Canvas

// scripts/generate-og-images.ts — Build-time generation
import { createCanvas, registerFont } from 'canvas';
import fs from 'fs';
import path from 'path';

registerFont('fonts/Inter-Bold.ttf', { family: 'Inter', weight: 'bold' });

interface OGConfig {
  title: string;
  slug: string;
  theme?: string;
}

function generateOGImage(config: OGConfig): Buffer {
  const { title, theme = '#0f172a' } = config;
  const width = 1200;
  const height = 630;
  const canvas = createCanvas(width, height);
  const ctx = canvas.getContext('2d');

  // Background gradient
  const gradient = ctx.createLinearGradient(0, 0, width, height);
  gradient.addColorStop(0, theme);
  gradient.addColorStop(1, '#1e293b');
  ctx.fillStyle = gradient;
  ctx.fillRect(0, 0, width, height);

  // Title text
  ctx.fillStyle = '#f8fafc';
  ctx.font = 'bold 52px Inter';
  const words = title.split(' ');
  let line = '';
  let y = 240;
  for (const word of words) {
    const test = line + word + ' ';
    if (ctx.measureText(test).width > 1040) {
      ctx.fillText(line.trim(), 80, y);
      line = word + ' ';
      y += 70;
    } else {
      line = test;
    }
  }
  ctx.fillText(line.trim(), 80, y);

  // Site name
  ctx.fillStyle = '#64748b';
  ctx.font = 'bold 24px Inter';
  ctx.fillText('example.com', 80, 560);

  return canvas.toBuffer('image/png');
}

// Generate for all posts
const posts: OGConfig[] = [
  { title: 'How to Build a REST API with Node.js', slug: 'rest-api-nodejs' },
  { title: 'TypeScript Generics Explained', slug: 'typescript-generics' },
];

for (const post of posts) {
  const buffer = generateOGImage(post);
  const outPath = path.join('public', 'og', `${post.slug}.png`);
  fs.mkdirSync(path.dirname(outPath), { recursive: true });
  fs.writeFileSync(outPath, buffer);
  console.log(`Generated: ${outPath}`);
}

Using Cloudinary URL Transforms

// Using Cloudinary URL-based image transformations
// No server-side code needed — just construct the URL

function getCloudinaryOGImage(title: string): string {
  const cloudName = 'your-cloud-name';
  const baseImage = 'og-template.png';  // Upload a background template first

  // URL-encode the title
  const encodedTitle = encodeURIComponent(title);

  // Cloudinary text overlay transformation
  return [
    `https://res.cloudinary.com/${cloudName}/image/upload`,
    // Resize to OG dimensions
    'w_1200,h_630,c_fill',
    // Add text overlay
    `l_text:Inter_52_bold:${encodedTitle}`,
    'co_rgb:f8fafc',       // Text color
    'g_west',              // Left-align
    'x_80,y_-40',          // Position
    'w_1040,c_fit',        // Max text width
    // Base image
    baseImage,
  ].join('/');
}

// Usage:
// <meta property="og:image"
//   content={getCloudinaryOGImage('How to Build a REST API with Node.js')} />

// Result URL looks like:
// https://res.cloudinary.com/your-cloud-name/image/upload/
//   w_1200,h_630,c_fill/
//   l_text:Inter_52_bold:How%20to%20Build%20a%20REST%20API/
//   co_rgb:f8fafc,g_west,x_80,y_-40,w_1040,c_fit/
//   og-template.png
