Frequently Asked Questions

Common questions about this tool and how to use the results.

What is Open Graph?

Open Graph is a protocol created by Facebook that controls how your page appears when shared on social media. It defines the title, description, and image shown in previews.

Do I need both OG and Twitter tags?

Twitter falls back to OG tags if twitter: tags are missing. But adding twitter:card ensures you get the large image format on X/Twitter.

What image size should I use?

1200x630 pixels is optimal for most platforms. It works well on Facebook, Twitter, LinkedIn, WhatsApp, and Slack.
