Will your link preview and rich results show up?
Before a link becomes a share card and before a page earns stars in search, a handful of tags decide how it looks. This reads every one and tells you, in order, what is missing or broken.
Why a great page still shares blank
The page can be perfect and the share still lands as a grey box, because the card and the rich result are built from tags a reader never sees. They are cheap to add and easy to break.
A blank share card costs the click
Post a link with no og:image and it renders as a grey box. People scroll past what looks broken, no matter how good the page is.
No structured data, no rich result
Stars, FAQs, and breadcrumbs in search come from JSON-LD. Skip it and you compete as a plain blue link against ones that stand out.
Broken markup fails silently
One malformed JSON-LD block is discarded whole, with no error on your page. You only notice when the rich result never shows.
One page in, a fix list out
Paste any page
A page people share or that you want in rich results. No sign-up, nothing installed.
It reads the markup
Open Graph, Twitter Card, and every JSON-LD block, checked and parsed in a few seconds.
You get a ranked fix list
Every gap, most costly first, with the exact tag to add or fix.
What it checks
The tags a platform reads to build a share card, and the structured data search reads to grant a rich result, each read straight from your page and scored by how much it costs you.
The Open Graph image
The one tag that decides whether a share is a rich card or a blank box, checked for presence.
Open Graph title and description
The headline and summary the share card uses, so you control the pitch, not the platform.
Twitter Card
Whether X shows a large image or a small one, and whether the card is declared at all.
JSON-LD structured data
Whether the page carries structured data, and what type, so it can qualify for rich results.
Broken JSON-LD
The malformed blocks search silently discards, flagged so a rich result is not lost to a stray comma.
Canonical link
A canonical so shares and structured data point at one URL instead of fragmenting across variants.
Straight talk about what it cannot see
It reads the raw HTML of your page, the way a platform first does. It checks the markup, and it will not pretend to do more.
It does not fetch your og:image
It confirms the tag is there, not that the image loads or is the right size. A broken image URL still passes this check, so verify the link.
It cannot promise a rich result
Valid structured data is required for stars and FAQs, but Google decides eligibility by its own rules. This gets you qualified, not guaranteed.
It reads HTML, not JavaScript
If your tags are injected with JavaScript after load, it says it could not read them rather than reporting markup it never saw.
It keeps the report, not your page
Your page is read, checked, and thrown away. Only the report is stored, and only for you.
