Use cases
When to check a share card
Sharing is where a page meets an audience that has not read it yet.
Before a launch post
Confirm the title, description and image are the ones you intended, before the link is out of your hands.
After a CMS or template change
Meta tags are easy to lose in a template refactor, and nothing on the page itself looks broken when they go.
Diagnosing a wrong preview
See exactly which tag a value came from, which is usually enough to explain a card nobody expected.
Scope and limits
What a preview can honestly show
These cards are representative renderings of the fetched metadata, not a copy of any platform's renderer.
Representative, not pixel-perfect
Facebook, X, LinkedIn, Slack and Discord each lay a card out differently, change it without notice and cache aggressively. This tool shows the metadata they would read and how a card built from it would look; it does not reproduce their layout and cannot flush their caches. The final URL, the canonical link and og:url are reported separately because they disagree more often than people expect.

FAQ
What comes up once a preview renders.
The preview here looks right but the real post does not. Why?
Almost always a cache. Networks store the metadata they scraped the first time a link was posted. Use the platform's own debugging or scraping tool to force a refresh after you fix the tags.
Do I need Twitter Card tags if I already have Open Graph?
Usually not for the text: X falls back to Open Graph. A twitter:card value is still worth setting, because it decides whether you get a small thumbnail or a large image.
What image size should I use?
1200 x 630 is the safe default across networks. Keep the file under a few hundred kilobytes and declare og:image:width and og:image:height so the card can be laid out before the image loads.
Is my page sent anywhere?
The page and its share image are fetched by our server to be read, then discarded. Nothing is stored, published or forwarded to any social network.
How to Plan a Modern Business Website That Actually Generates Leads
A business website that doesn't generate leads isn't a marketing problem first, it's usually a structure problem. These are the decisions that separate a brochure from a website that works.

Website Audit in 2026: The Complete SEO, Core Web Vitals, Accessibility and Security Checklist
A good website audit is not a single Lighthouse score or a list of several dozen automated warnings. It should answer four questions: can a search engine correctly discover and understand the website, can a user complete their task efficiently, is the website fast enough, and does it expose the owner or visitors to unnecessary risk?
