Do I need separate tags for Twitter?

Twitter supports its own meta tags (twitter:card, twitter:title, etc.) but will fall back to Open Graph tags if Twitter-specific tags are absent. For best results, include both.

How do I debug social share previews?

After updating your OG tags, use Facebook's Sharing Debugger or our preview tool to verify. Social platforms cache previous OG data, so you may need to scrape the URL again to refresh.

What Is Open Graph?

Open Graph is a protocol created by Facebook that allows web pages to control how they appear when shared on social media platforms. When someone shares a URL on Facebook, LinkedIn, Twitter, or messaging apps, Open Graph meta tags determine the title, description, image, and URL displayed in the preview card. Without proper Open Graph tags, shared links may show incorrect images, missing descriptions, or generic previews that fail to attract clicks.
