What are Open Graph tags?
Open Graph (OG) tags are meta tags in your HTML that control how your content appears when shared on social media platforms like Facebook, LinkedIn, Slack, and Discord. They let you specify a title, description, and preview image for each page.
Why do my shared links look wrong on social media?
If your links show the wrong image, title, or description when shared, it usually means your Open Graph tags are missing or incorrect. Use this checker to see exactly what tags your page has and what platforms will display.
What is the difference between OG tags and Twitter Cards?
Open Graph tags (og:title, og:description, og:image) are used by Facebook, LinkedIn, and most platforms. Twitter/X uses its own twitter:card, twitter:title, and twitter:image tags — but will fall back to OG tags if Twitter-specific tags are missing.
What is the recommended og:image size?
The recommended size for og:image is 1200×630 pixels. This works well across Facebook, LinkedIn, Twitter, and Slack. Images should be under 8MB and in JPG or PNG format.
How do I fix "Missing og:image" warnings?
Add a <meta property="og:image" content="https://yoursite.com/image.jpg" /> tag in the <head> of your HTML. The image URL must be absolute (starting with https://). Relative paths won't work.
Do Open Graph tags affect SEO?
OG tags don't directly affect search rankings, but they significantly impact click-through rates from social media. A compelling preview image and title can dramatically increase engagement when your content is shared.
