The Ultimate Guide to Meta Tags for Better SEO

Meta tags are invisible snippets of text that describe a page's content. They don't appear on the page itself but are crucial for SEO and how your content appears in search results and on social media platforms.

Essential Meta Tags for Every Page

1. Title Tag

The most important meta tag. It appears in search results, browser tabs, and social shares.

<title>Your Page Title | Brand Name</title>

Best Practices:

• Keep it between 50-60 characters
• Include your primary keyword near the beginning
• Make it compelling and click-worthy
• Include your brand name at the end

2. Meta Description

The summary that appears under your title in search results. While not a direct ranking factor, it significantly impacts click-through rates.

<meta name="description" content="Your compelling description here" />

Best Practices:

• Keep it between 150-160 characters
• Include primary and secondary keywords naturally
• Write a compelling call-to-action
• Accurately describe the page content

3. Viewport Meta Tag

Essential for responsive design and mobile-first indexing:

<meta name="viewport" content="width=device-width, initial-scale=1" />

Open Graph Tags for Social Media

Open Graph tags control how your content appears when shared on Facebook, LinkedIn, and other platforms:

<meta property="og:title" content="Your Title" />
<meta property="og:description" content="Your description" />
<meta property="og:image" content="https://yoursite.com/image.jpg" />
<meta property="og:url" content="https://yoursite.com/page" />
<meta property="og:type" content="website" />
<meta property="og:site_name" content="Your Site Name" />

Image Requirements:

• Recommended size: 1200 x 630 pixels
• Minimum size: 600 x 315 pixels
• Aspect ratio: 1.91:1
• File size: Under 8MB

Twitter Card Tags

Optimize how your content looks when shared on Twitter/X:

<meta name="twitter:card" content="summary_large_image" />
<meta name="twitter:site" content="@yourusername" />
<meta name="twitter:title" content="Your Title" />
<meta name="twitter:description" content="Your description" />
<meta name="twitter:image" content="https://yoursite.com/image.jpg" />

Card Types:

• summary: Small image, title, and description
• summary_large_image: Large prominent image (recommended)
• app: For mobile app promotion
• player: For video/audio content

    title: 'Your OG Title',
    description: 'Your OG description',
    images: [
      {
        url: '/og-image.jpg',
        width: 1200,
        height: 630,
        alt: 'Image description',
      },
    ],
    locale: 'en_US',
    type: 'website',
  },
  twitter: {
    card: 'summary_large_image',
    title: 'Your Twitter Title',
    description: 'Your Twitter description',
    images: ['/twitter-image.jpg'],
    creator: '@yourusername',
  },
}
