Which twitter:card value should I use?

Use summary_large_image for a wide image above the title. Use summary for a small square thumbnail beside the text.

Do I need both twitter: and og: tags?

Not always. X reads og: tags when the twitter: equivalents are missing, so you only need twitter:card plus og: tags in many cases.

Can I still validate cards with the old Card Validator?

X retired the standalone validator. The reliable check is to paste the live URL into a post draft and see the card that appears.

Will Google display this exact title and description?

Not necessarily. Search engines can rewrite snippets based on the query and page content. The preview helps you plan clear metadata but cannot guarantee the final search result.

Should the canonical URL be absolute?

Yes. Use the preferred public HTTPS URL for the page, including the correct hostname and path.

Does this tool download or validate my social image?

PostlyBee does not download or validate the image. Your browser loads it from its address so the preview can show it. Validate the deployed image dimensions, format, and availability separately.

Are special characters escaped in the copied HTML?

Yes. The generated title and meta values escape HTML-sensitive characters before they are copied.

Does PostlyBee crawl the URL I enter?

Only when you choose Fetch tags. PostlyBee then downloads that one public HTTPS page to read its title, description, and image tags, and does not store it. Private, local, and internal addresses are blocked. Text you type by hand never leaves your browser.

Practical guide

Get a large card instead of a bare link

Without card tags a link on X can appear as plain text. Setting twitter:card to summary_large_image tells X to show the image, title, and domain as a card, which takes up far more of the timeline.

Because X falls back to Open Graph, one set of og: tags plus a single twitter:card line is often enough. Add twitter-specific tags only when you want different copy for X.

Privacy: Text you type stays in this browser tab. If you import a URL, PostlyBee downloads that public page once to read its tags and does not store it. Your browser loads the preview image directly from its address.

Pro tips

Pro tips for X (Twitter) metadata

Pick the card type

twitter:card selects the layout. summary_large_image shows a wide image above the text and is the usual choice for articles and landing pages.

Falls back to Open Graph

When twitter:title, twitter:description, or twitter:image are missing, X reads the matching og: tags. Set both only when the X version should differ.

Titles are short, images are 2:1

Keep titles near 70 characters and use a 2:1 image so nothing important is cropped. Large files above 5 MB are not shown.
