Question 1

What is the Open Graph protocol?

Accepted Answer

Open Graph (OG) is a meta tag protocol invented by Facebook in 2010 to control how URLs render when shared on social platforms. It defines tags like og:title, og:description, og:image, and og:type that platforms read to build a rich preview card. Despite being Facebook's invention, it became the de facto standard, Twitter, LinkedIn, WhatsApp, Slack, Discord, iMessage, Telegram, and many more all read OG tags.

Question 2

What are the essential Open Graph tags?

Accepted Answer

Four are required: og:title (the headline of the preview), og:description (the body text), og:image (the preview thumbnail, 1200×630 recommended), og:url (the canonical URL of the page). Strongly recommended: og:type (website/article/product), og:site_name (your brand), og:locale (en_US, fr_FR, etc.). Image-specific: og:image:width, og:image:height, og:image:alt for accessibility.

Question 3

What's the ideal og:image size?

Accepted Answer

1200×630 pixels (1.91:1 aspect ratio) is the universal recommendation, works for Facebook's summary_large_image, LinkedIn, Twitter's summary_large_image card, Slack's expanded preview. Minimum: 600×315. Under 1 MB to avoid slow loading. Keep critical content (logos, faces, text) centered, WhatsApp and some platforms crop to square.

Question 4

Why do my share previews show old content?

Accepted Answer

Facebook, LinkedIn, and Twitter aggressively cache OG previews. When you update meta tags, the cached version persists until the platform refreshes, sometimes hours, sometimes weeks. Force a refresh: Facebook (developers.facebook.com/tools/debug, click 'Scrape Again'); Twitter (cards-dev.twitter.com/validator); LinkedIn (linkedin.com/post-inspector). Each platform has its own debugger that scrapes fresh meta tags.

Question 5

Do Twitter Cards still need their own tags?

Accepted Answer

Mostly no, Twitter falls back to og:title, og:description, og:image. But three Twitter-specific tags add value: twitter:card (declares 'summary' or 'summary_large_image' layout), twitter:site (@your_brand handle), twitter:creator (@author handle for analytics attribution). Set those three; let the rest fall back to OG.

Question 6

What og:type values matter?

Accepted Answer

website is the default. article unlocks article:published_time, article:author, article:section, article:tag, used by Facebook Instant Articles, LinkedIn rich previews. product unlocks product:price:amount, product:price:currency for e-commerce. video.movie, video.episode for video content. music.song, music.album for audio. profile for personal pages. For most blog posts, og:type="article" plus the article:* tags gives the richest LinkedIn render.

Question 7

What about multiple images?

Accepted Answer

OG supports multiple og:image tags, platforms pick the best one (Facebook lets users choose during share). Useful when your page has hero images that work better for some platforms than others. Order matters: most platforms use the first listed; some take the largest. List your preferred default first.

Question 8

Is the generator using my data on a server?

Accepted Answer

No. Open Graph tag generation is purely HTML string assembly, all done in your browser. Titles, descriptions, image URLs, and other inputs stay in your tab. The preview is rendered locally with your image URL fetched directly by the browser (not proxied).

Question 9

What standards does Open Graph Meta Generator validate against?

Accepted Answer

Open Graph Meta Generator checks compliance with Open Graph protocol, Twitter Card specification.
