よくある質問

What are Open Graph meta tags?
Open Graph (OG) meta tags are HTML meta elements that control how your web page appears when shared on social media platforms like Facebook, LinkedIn, Pinterest, and messaging apps. The most important tags are og:title (the headline), og:description (the summary text), and og:image (the preview image). Without these tags, social platforms make their best guess about what to display, which often results in missing images or incorrect text.
-
What is the difference between Open Graph tags and Twitter Cards?
Open Graph tags were created by Facebook and are used by most social platforms including LinkedIn, Pinterest, and WhatsApp. Twitter Cards are Twitter-specific meta tags that control how links appear in tweets. Twitter will use its own twitter:* tags first, then fall back to Open Graph tags if Twitter-specific tags are missing. For maximum compatibility, it is best to include both Open Graph and Twitter Card tags on your pages.
-
Which Open Graph tags are required?
The four essential Open Graph tags are og:title, og:description, og:image, and og:url. Without og:title and og:description, platforms will try to extract text from your page content, which may not be what you want. Without og:image, your shared link will appear without a preview image, significantly reducing click-through rates. The og:url tag ensures the canonical URL is used when your page is shared.
