Social platforms cache a link’s preview data after the first time it’s shared, sometimes for days or weeks, to avoid re-fetching your page every time someone posts the link. This tool always fetches your page fresh, so it will show your current tags correctly, but Facebook, LinkedIn, or X may still show an outdated cached version to other users until you force a re-scrape using that platform’s own debugging tool.

The widely recommended size is 1200 by 630 pixels, an aspect ratio of roughly 1.91:1, which displays sharply across Facebook, LinkedIn, X, and most messaging apps without awkward cropping. Keep the file size reasonable, under 5MB, and use JPG or PNG format for the broadest compatibility. Avoid putting critical text near the edges, since some platforms crop the image slightly differently.

Not strictly, X will fall back to your Open Graph tags if dedicated twitter: tags are missing, and this tool reflects that same fallback behavior in its preview. However, adding the twitter:card, twitter:title, twitter:description, and twitter:image tags explicitly gives you more precise control over how the card looks specifically on X, since it doesn’t always interpret Open Graph tags identically to Facebook.

The most common causes are the tag missing entirely, the image URL being a relative path instead of a full absolute URL starting with https://, the image server blocking automated or cross origin requests, or the image simply no longer existing at that URL. Check the tag table in the results to confirm the exact URL detected, then open that URL directly in a new browser tab to verify it loads correctly.

Open Graph tags are not a direct Google ranking factor, but they meaningfully influence how often your content gets shared and clicked on social media, since a compelling preview card increases click-through rate compared to a generic or broken looking link. More shares and clicks can indirectly support SEO through increased traffic, backlinks, and brand signals, even though the tags themselves aren’t read by Google’s ranking algorithm the way title tags are.

The page needs to be publicly reachable on the internet for this tool, or any social platform, to fetch and read its tags, password protected pages, localhost URLs, or staging environments behind a login won’t work. Most website builders and CMS platforms offer a staging or preview URL that’s publicly reachable but not linked anywhere, which works fine for testing purposes.

og:type tells the consuming platform what kind of content the page represents, common values include “website” for general pages, “article” for blog posts and news content, and “product” for e-commerce items. Some platforms use this to display additional structured metadata, like an article’s publish date or a product’s price, when the corresponding more specific Open Graph fields are also present.

No, this site does not log or store the URLs you check. The page fetch is routed through a public proxy service to bypass browser cross origin restrictions, and parsing happens entirely in your browser.
