Why Your Launch Link Looks Broken When Shared (And How to Fix It)
Most launch-day traffic comes from a shared link, not a Google search — and a missing meta tag is usually why that link looks broken when someone shares it.
On launch day, most of your traffic doesn't come from someone typing your product name into Google — it comes from a link shared in a Slack channel, a Discord server, a tweet, or a launch community. What that shared link looks like is controlled entirely by a handful of meta tags, and getting them wrong is one of the most common, most avoidable launch-day mistakes.
What actually controls a link preview
When a platform generates a preview card for a shared link, it's reading a specific set of meta tags from your page's <head> — not a screenshot, not your favicon, not a guess. Two families of tags matter:
Open Graph tags (
og:title,og:description,og:image,og:url,og:site_name,og:type) — the standard most platforms read, including Facebook, LinkedIn, Slack, and Discord.Twitter Card tags (
twitter:card,twitter:title,twitter:description,twitter:image) — read specifically by X/Twitter, which doesn't always fall back to Open Graph tags cleanly.
If either set is missing, the platform either falls back to whatever it can scrape from the page (often an unpredictable result) or shows a blank, broken-looking card.
The four things worth checking before launch
1. Is there an og:image, and is it the right size?
Most platforms expect roughly 1200×630px. Too small and it gets upscaled and blurry; wildly off-aspect-ratio and it gets cropped in a way you didn't intend. No image at all means most platforms either show nothing or fall back to a generic site icon — a meaningfully worse first impression on a link that's about to get shared dozens of times in one day.
2. Do og:title and og:description say what you actually want them to say?
Without explicit Open Graph tags, some platforms fall back to your page's regular <title> and meta description — which are optimized for search, not necessarily for a scroll-stopping share. It's worth setting these independently if your ideal "Google search" framing and your ideal "shared link" framing are different.
3. Is twitter:card set?
Without it, X often won't render a large image card at all, even if your Open Graph tags are otherwise complete — this is the single most common reason a link looks fine everywhere except specifically on X.
4. Does og:url point to the canonical URL?
If it's missing or points to the wrong variant of your URL, shares can end up crediting or linking to the wrong page — worth a quick check, especially if your page is reachable through more than one URL path.
How to check yours before launch day
You don't need to manually publish test posts on four different platforms to see how your card renders. LaunchZone's free Open Graph Checker reads a URL's actual Open Graph and Twitter Card tags and shows you what platforms will render — worth running once right before you submit, since it's exactly the kind of thing that's invisible until someone else shares your link and it looks wrong.

Questions this article answers
Why does my link look fine on LinkedIn but broken on X?
X specifically reads Twitter Card tags (twitter:card, etc.) and doesn't always fall back cleanly to Open Graph tags the way other platforms do. A page with complete Open Graph tags but no Twitter Card tags commonly renders correctly everywhere except X.
What image size should og:image be?
Roughly 1200×630px is the safe default most platforms expect. Smaller images get upscaled and look blurry; very different aspect ratios often get cropped unpredictably.
Do I need separate Open Graph and Twitter Card tags, or does one cover both?
Twitter/X will use Open Graph tags as a fallback in some cases, but it's not fully reliable — setting Twitter Card tags explicitly is the only way to guarantee how a link renders there.
