og:title and og:description
The core Open Graph title and description are read and previewed, since these become the headline and summary of the share card.
og:image
The Open Graph image is fetched and shown, because a missing or wrong-sized og:image is the most common reason shared links look bare.
Twitter Card tags
Twitter Card tags are read to preview how the link renders on X, including the card type and image.
Platform rendering
The card is rendered the way major platforms display it, so truncation and layout are visible before sharing.
Fallback behavior
The interaction between Twitter Card and Open Graph is surfaced, since X falls back to Open Graph when Card tags are absent.
Open Graph tags do not directly influence rankings, but they govern the click-through and reach of every link shared on social. A link with a strong image and clear title earns far more clicks than a bare URL, and those clicks drive the referral traffic, engagement and links that do influence rankings. The share card is effectively the ad creative for organic distribution, and most pages leave it to chance.
Missing og:image
A missing Open Graph image is fixed by adding an og:image around 1200×630 pixels, since the image is the largest and most clicked element of a share card.
Missing og:title or og:description
Missing Open Graph text is fixed by adding og:title and og:description, otherwise platforms guess from page content, often poorly.
Wrong image when shared
A wrong shared image is fixed by correcting the og:image and re-scraping the URL with the platform's sharing debugger to clear the cached preview.
Image too small
An undersized share image is fixed by supplying one at least 1200×630, because small images render as a cramped thumbnail instead of a large card.
No Twitter Card tags
Absent Twitter Card tags are acceptable when Open Graph is present, since X falls back to Open Graph, but explicit Twitter tags give the most control on X.
What are Open Graph tags?
Open Graph tags are meta tags that control the title, description and image shown when a page is shared on Facebook, LinkedIn, Slack and most platforms.
What image size should og:image be?
An og:image of about 1200×630 pixels renders well as a large card across the major platforms without cropping awkwardly.
Why does the wrong image show when I share my page?
A wrong shared image is usually a missing, incorrect or too-small og:image, or a cached preview that needs re-scraping with the platform's debugger.
Do Open Graph tags affect SEO?
Open Graph tags do not directly affect rankings. They strongly affect social click-through, which drives the referral traffic and links that do.
What is the difference between Open Graph and Twitter Cards?
Open Graph controls previews on Facebook, LinkedIn, Slack and most platforms, while Twitter Card tags control previews on X, which falls back to Open Graph if they are absent.
Is this Open Graph preview free?
Our Open Graph Preview is free, with no sign-up, no limits, and nothing stored. The page you submit is fetched server-side, analyzed, and then discarded.
