What good social tags look like
When your link card is broken it shows a bare URL with no image, which kills click-through on every platform. A complete set covers four things:
- og:image is the single biggest one. Use an absolute URL, ideally 1200x630px. A missing image is the most common reason a shared link looks empty.
- og:title and og:description control the headline and blurb on Facebook and LinkedIn. Keep the title under ~60 characters and the description under ~155 so nothing gets cut.
- twitter:card set to
summary_large_imagegives you the big image card on X instead of a tiny thumbnail. - og:url and a canonical tell platforms and Google which URL is the real one, so shares and SEO equity point to the same page.
Need to write the title and description first? Use our free Meta & Title Tag Generator, then paste the page back here to confirm the share cards render.
A perfect share card still needs someone searching for the page.
Open Graph tags win you the click once a link is seen, but they do not create demand. Before you invest in a page, confirm real people search the term and that a newer site can realistically rank for it. Semrush gives you live search volume, keyword difficulty, and the intent your competitors already win.

Open Graph preview, questions answered
Is this Open Graph preview tool free?
Yes. It runs entirely in your browser with no signup and no usage limit. Nothing you paste is uploaded or stored, so you can safely check pages that are not published yet.
Why not just use the Facebook or Twitter validator?
X (Twitter) retired its public Card Validator in 2023, and Facebook's Sharing Debugger now requires a login and only works on already-public URLs. This tool reads the HTML you paste, so it works on local, staging and unpublished pages instantly with no account.
What tags does it check?
The title and meta description, the canonical URL, and the full Open Graph set (og:title, og:description, og:image, og:url, og:type, og:site_name) plus Twitter Card tags (twitter:card, twitter:title, twitter:description, twitter:image). It flags anything missing and warns when a title or description is too long for the card.
The image is not showing in my preview. Why?
Two common reasons. First, og:image must be an absolute URL (starting with https://), not a relative path. Second, your image host may block hotlinking from other sites, so it loads on your page but not in our preview. The checklist will tell you if the tag itself is missing or relative; if the tag is correct, the real platforms will usually still fetch it.
