Everything about Open Graph and Twitter Cards
Open Graph tags (OG) control how your link looks when someone shares the page on WhatsApp, LinkedIn, Facebook, or any link preview. They set the card title, description, and image. Without these tags, the social network guesses the content and the result usually looks empty or broken.
What OG and Twitter tags are
They are meta tag lines in the page <head>, shaped like <meta property="og:title" content="..."> for Open Graph and <meta name="twitter:card" content="..."> for X (Twitter). Open Graph is read by most networks; the twitter: tags fine-tune the card on X when you want a result different from the OG default.
Which tags matter
| Tag | What it does |
|---|---|
| og:title | Title shown on the shared card |
| og:description | Short text below the title |
| og:image | Large card image (the biggest driver of clicks) |
| og:url | Canonical URL of the shared content |
| og:type | Content type, such as website or article |
| og:site_name | Site name shown next to the card |
| twitter:card | Card format on X, such as summary_large_image |
Ideal image size
Use a 1200x630 pixel og:image (1.91:1 ratio), in JPG or PNG, under 5 MB, with an absolute URL starting with https://. That size fills the large card without cropping on most networks. Small images turn into a tiny icon next to the text.
Where to paste the tags
All OG and Twitter tags live inside the HTML <head>, alongside the other meta tags. After publishing, revalidate the social network cache, because it keeps the first version it saw and may take a while to update the preview.
Open Graph questions
Is the checker free?
Yes, free and no sign up. Paste the URL and get the OG and Twitter tags instantly, with a card preview.
Which are the essential tags?
og:title, og:description, and og:image. With those three, the share card is already complete on most networks.
What is the ideal og:image size?
1200x630 pixels, 1.91:1 ratio, in JPG or PNG, with an absolute URL and under 5 MB.
Do I need twitter: tags if I already have OG?
Not always. X falls back to the OG tags. The twitter: tags are useful when you want a different title, description, or card only on X.
I changed the image and the preview is still old, why?
Networks cache the first version. Republish and use the network's official validator to force a re-read of the link.
Is my data stored?
The check runs on demand and the page content is not stored.
