Two audit tools, one sharing workflow

Meta Tag Analyzer vs Open Graph Preview

Both tools work with the same raw data — your page's `<head>` tags — but they produce very different outputs. The Meta Tag Analyzer is a full audit that scores every important meta tag out of 100. The Open Graph Preview is a visual mockup of what your page looks like when someone pastes your URL into Facebook, X, or LinkedIn. Use the Analyzer to make sure nothing is missing; use the OG Preview to make sure what IS there looks good.

When to use which

Use Meta Tag Analyzer

Before you hit publish on any new page. The Analyzer catches the invisible stuff — missing robots tags, duplicate canonicals, incomplete OG sets — that your readers never see but Google absolutely does. A quick paste-HTML run takes 20 seconds and will flag issues you'd miss scrolling through view-source.

Use OG & Twitter Preview

Right before you share a link on social or send it in an email campaign. Your OG card IS your headline in that context — if it's ugly, broken, or missing, your click-through rate collapses. The Preview shows exactly what Facebook, X, and LinkedIn will render, so you fix problems before your audience sees them.

Using them together

Run the Analyzer first as a pre-publish gate. If it flags a missing `og:image` or a too-short `og:description`, hop to the OG Preview, edit those specific tags, and verify the card looks right before you re-deploy. That one-two combo catches the widest range of meta-level issues.

FAQ
If I use the OG Preview, do I still need the Meta Analyzer?
Yes. OG tags are only one slice of your meta stack. The Analyzer also checks canonical, robots, hreflang, and security-relevant headers that have nothing to do with social sharing but everything to do with how Google indexes your page.
Can both tools fetch from a URL?
Yes. Both support URL fetch mode (Phase 2 upgrade). Paste a URL, we fetch the page, and you see results within a second or two.
Which one should I bookmark?
Bookmark the Meta Tag Analyzer — it has broader coverage. Jump into the OG Preview when you specifically need to verify a share card.
