How to Generate Open Graph and Twitter Card Tags

Configure rich, visually stunning social sharing previews in four quick steps:

Draft an Eye-Catching Title: Enter a compelling social headline in the Social Page Title field. Aim for 60 to 70 characters to avoid truncation across mobile feeds.
Write an Actionable Summary: Provide a concise description that gives users a clear reason to click and read your content.
Provide an Absolute Image URL: Paste the direct HTTPS link to your 1200×630 pixel featured graphic. Avoid relative paths or local filenames.
Inspect Live Visual Previews: Toggle between the Facebook / LinkedIn and Twitter / X tabs to verify image cropping, typography, and card dimensions.
Copy and Embed Tags: Click Copy HTML Tags and paste the resulting <meta> elements into the <head> section of your HTML template.

What is the Open Graph Protocol?

The Open Graph (OG) protocol is an open metadata standard introduced by Facebook in 2010. It enables any web page to become a rich social graph object. By placing standardized <meta property="og:..." content="..."> tags in your HTML document header, you instruct social crawlers exactly which title, description, image, and canonical URL to render when users share your links on Facebook, LinkedIn, Pinterest, Slack, WhatsApp, and iMessage.

Twitter (now X) uses a similar proprietary standard known as Twitter Cards, configured via <meta name="twitter:..." content="...">. When Twitter Cards are present alongside Open Graph tags, Twitter prioritizes its own native card directives while falling back to standard OG attributes for any missing values.

Best Practices vs. Common Mistakes in Social Metadata

Parameter	Recommended Best Practice	Common Mistake to Avoid
Image Dimensions	1200 × 630 pixels (1.91:1 ratio).	Using square 1:1 or tiny 200px thumbnails that render with awkward side borders.
Image File Size	Keep under 1MB (maximum 5MB) in WebP or JPG.	Uploading 15MB uncompressed PNGs that cause crawler timeout errors.
URL Format	Absolute URL with HTTPS (e.g. `https://...`).	Using relative paths (e.g. `/og-image.jpg`) which crawlers cannot resolve.
Card Type	Use `summary_large_image` on Twitter for maximum impact.	Omitting the card type, defaulting to a small compressed thumbnail.
Text in Graphics	Keep text centered within the safe 1000 × 520 px inner zone.	Placing text near edges where mobile app cropping cuts off headlines.

Frequently Asked Questions

What is the recommended image dimension for Open Graph tags?

The optimal image dimension for Open Graph and Twitter summary_large_image cards is 1200 x 630 pixels (an aspect ratio of 1.91:1). Keeping your image file size under 5MB ensures high-resolution display without slow social crawler retrieval timeouts.

What happens if a web page does not declare Open Graph tags?

When OG tags are missing, platforms like Facebook, LinkedIn, and Slack attempt to scrape random images and arbitrary paragraph text from the HTML document. This frequently results in distorted images, incorrect headlines, or broken link cards.

Can I use relative URLs in og:image and og:url tags?

No. The Open Graph protocol explicitly requires absolute canonical URLs, including the protocol scheme (e.g., 'https://www.example.com/images/cover.jpg'). Relative paths like '/images/cover.jpg' will fail to render on social networks.

Does Twitter still support Open Graph if Twitter Card tags are omitted?

Yes, Twitter's crawler will fall back to og:title, og:description, and og:image if twitter:title and twitter:image are missing. However, explicitly including twitter:card with 'summary_large_image' ensures full-width card rendering.

How do social platforms cache Open Graph tags and how do I refresh them?

Social platforms aggressively cache scraped OG tags for up to 30 days. To force a refresh after updating your tags, submit your URL to the Facebook Sharing Debugger, LinkedIn Post Inspector, or Twitter Card Validator.
