- What are Open Graph meta tags and which platforms use them?
- Open Graph (OG) tags are HTML meta elements using the 'property' attribute (og:title, og:description, og:image, og:url, og:type) that control how URLs appear as rich previews when shared on social platforms. Facebook, LinkedIn, Pinterest, Slack, Discord, WhatsApp, iMessage, and many other apps read Open Graph tags. Without them, platforms generate generic or incorrect previews from page content.
- Do I need both Open Graph tags and Twitter Card tags?
- Yes, for maximum control. While X (Twitter) falls back to Open Graph tags when Twitter Card tags are absent, using both protocols lets you customize previews independently for each platform. Twitter Card tags use the 'name' attribute (twitter:card, twitter:title, twitter:description, twitter:image) and support card types like 'summary' and 'summary_large_image' that have no OG equivalent.
- What is the recommended og:image size for social media sharing?
- The recommended og:image dimensions are 1200x630 pixels (1.91:1 aspect ratio) for optimal display across Facebook, LinkedIn, and Twitter summary_large_image cards. Minimum size is 600x315 pixels. Images must be hosted on HTTPS URLs, under 5MB file size, and in JPG, PNG, or WebP format. Always use absolute URLs — relative paths cannot be resolved by social media crawlers.
- How long should my title tag and meta description be for Google SEO?
- Google displays approximately 60 characters (or 580 pixels width) of the title tag and approximately 155-160 characters of the meta description in search result snippets. Titles exceeding 60 characters get truncated with ellipsis. Write compelling, keyword-rich titles under 60 characters and descriptions under 160 characters that include a clear call-to-action to maximize click-through rates.
- How do I add generated meta tags to Next.js, WordPress, or Shopify?
- In Next.js App Router, use the metadata export or generateMetadata() function in page.tsx. In WordPress, paste tags in your theme's header.php or use an SEO plugin like Yoast/RankMath. In Shopify, add tags to theme.liquid in the <head> section. For static HTML sites, paste the generated tags directly between <head> and </head>. The generated HTML from this tool is compatible with all these implementations.
- How do I test and validate my Open Graph and Twitter Card tags after deployment?
- Use Facebook's Sharing Debugger (developers.facebook.com/tools/debug) to preview OG tags and clear cached previews. Use Twitter's Card Validator to test Twitter Card rendering. Use LinkedIn's Post Inspector for LinkedIn previews. These tools fetch your page, parse the meta tags, and show exactly how the shared link will appear — including any errors or missing required properties.
- Is this meta tag generator free to use?
- Yes, completely free with no signup required, no usage limits, and no ads. Generate meta tags for unlimited pages. All processing runs in your browser — no data is sent to any server.
