Question 1

Why does my page show the wrong image when shared on Facebook?

Accepted Answer

Facebook caches OG data the first time it crawls a URL. If you update your og:image tag, Facebook will not automatically re-fetch it. You need to manually clear the cache using Facebook's Sharing Debugger tool (developers.facebook.com/tools/debug). Enter your URL and click "Scrape Again" to force a fresh fetch of your updated OG tags.

Question 2

What is the recommended og:image size for social media?

Accepted Answer

Use 1200 × 630 pixels for maximum compatibility across all platforms. This 1.91:1 aspect ratio is the standard supported by Facebook, X/Twitter (large card), and LinkedIn. Minimum dimensions are around 600 × 314px, but smaller images may appear as tiny thumbnails rather than large preview cards, significantly reducing click-through rates.

Question 3

Does this tool actually fetch my page and read its existing tags?

Accepted Answer

No — this tool is an input-based generator, not a live URL scraper. You provide the title, description, image URL, and other details manually, and the tool renders what the social card will look like based on those inputs. This is intentional: it keeps the tool fully client-side and private, with no server requests, and it lets you preview cards before your page is even published.

Question 4

Do I need separate og:image tags for each social platform?

Accepted Answer

Not necessarily. Facebook, LinkedIn, and X/Twitter all read the standard og:image tag, so one well-sized image (1200×630px) works across all three. You can add twitter:image specifically for X if you want a different image for Twitter cards, but it is not required if the og:image is already set correctly.

Question 5

What og:type should I use for my content?

Accepted Answer

For most web pages — blog posts, landing pages, documentation — use "website" as the og:type. Use "article" for news articles and blog posts to enable article-specific markup (like publish date and author). Use "product" for e-commerce pages. Specialized types like "video.movie" or "music.song" have additional required properties beyond the standard four core tags.

Question 6

Why is LinkedIn not updating my link preview even after I updated the tags?

Accepted Answer

LinkedIn aggressively caches URL previews and does not automatically re-scrape them. To force LinkedIn to re-read your updated OG tags, use the LinkedIn Post Inspector tool at linkedin.com/post-inspector. Enter your URL and click "Inspect." The next time someone shares your link, LinkedIn will use the newly scraped data.

Question 7

Does my og:description need to be different from my meta description?

Accepted Answer

They can be the same, but it is worth optimizing them separately. The meta description is shown on Google search results pages and should be written for search intent. The og:description is shown on social platforms and should be written for emotional engagement and shareability. A one-size-fits-all description often underperforms in both contexts.
