Frequently Asked Questions
What are Open Graph tags?
They are small meta tags in your page head that tell social networks which title, description and image to show when your link is shared.
Why does my old image still show?
Social networks save the preview for some time. Use the Facebook Sharing Debugger or LinkedIn Post Inspector to refresh it.
Does Open Graph help SEO?
Not directly. It improves how your link looks when shared, which can bring more clicks and visitors.
Does X use Open Graph?
Yes. X reads twitter: tags first and falls back to Open Graph tags. Add twitter:card to choose the large image style.
Why is my image not shown in the preview?
The image address may be wrong, private, too small or blocked. Use a full https address.
Why can the checker not open my page?
The page must be public. Some sites block automated visits.
