Why does my link preview show no image?

Almost always a relative og:image URL. Platforms fetch the image from their servers, where /images/og.png resolves to nothing. Make it absolute — https://yourdomain.com/images/og.png. Second most likely: the platform has cached an older version of the page.

Do I need Twitter tags as well as Open Graph?

X falls back to Open Graph, so you are not broken without them — but twitter:card decides between a large image and a small one, and without it you often get the small one. Both sets are generated here; it is two extra lines.

I changed the tags and the old preview still shows. Why?

Caching, and it can last days. Use Facebook's Sharing Debugger to force a re-fetch — that also clears WhatsApp, which uses the same cache. LinkedIn's Post Inspector does the same for LinkedIn.

Does Open Graph affect SEO?

Not directly — these tags are for social platforms, not search engines. What they affect is whether shared links get clicked, and links that get clicked get shared further. The effect on search is real but indirect.

Platforms cache aggressively. After changing these tags, run the page through Facebook's Sharing Debugger to force a refresh — otherwise the old preview keeps appearing for days.

Why use it

Built to be genuinely useful

See the card before you ship

Feed-style and WhatsApp-style previews, so you know what people will actually see.

Catches the usual killer

A relative og:image is why most previews show a grey box. Platforms fetch it from their own servers, where /og.png means nothing.

Twitter tags included

X reads its own tags and falls back awkwardly. Both sets are generated together.

Nothing is uploaded

It runs in your browser. Your keyword list and your draft copy are a content plan — they should not have to leave the machine to be analysed.

How it works

Three steps

1
Enter the title, description, URL and image.
2
Check the previews and the warnings.
3
Copy the tags into your page's head.

Why the preview is worth more than the traffic

When a link is shared on WhatsApp, LinkedIn or X, the preview card is the entire advertisement. A card with a clear image and a real headline is a link people tap; a bare blue URL with no image is a link people scroll past, whatever is behind it.

In India this weighs more heavily than the global averages suggest, because so much sharing happens in WhatsApp groups rather than on public feeds. A link forwarded into a group of forty people either carries a card or does not, and that single difference decides whether anyone opens it.

It costs about six lines of HTML, set once per page, usually by a template. It is one of the few genuinely high-return, low-effort things left in this area.

The mistake that breaks most cards

A relative og:image. Writing content="/images/og.png" works everywhere else in HTML, because your browser resolves it against the current page — and fails here, because Facebook, LinkedIn and WhatsApp fetch the image from their own servers, where that path resolves to nothing.

The result is a card with no image and no error message, which is why it survives so long: nothing tells you, and the person who shared the link is not the person who wrote the tag. Every image URL must be absolute, starting with https://.

Two more that follow closely: an image served over http, which some platforms refuse to load into an HTTPS context, and og:url pointing at a tracking-parameter version of the page, which fragments the share count across every campaign that ever linked to it.

Sizing, caching and testing

1200×630 is the size to use. It is the standard large-format ratio, and it degrades acceptably everywhere else — including WhatsApp's small square thumbnail, which centre-crops. Keep essential text away from the edges, because different platforms crop differently.

Every platform caches aggressively. Change your tags and the old preview keeps appearing for days, which is exactly when people conclude the tags do not work and start rewriting things that were already correct.

Force a refresh instead: Facebook's Sharing Debugger, LinkedIn's Post Inspector and X's card validator each re-fetch on demand. WhatsApp uses Facebook's cache, so the Sharing Debugger covers it too. Run those once after publishing and the problem disappears.
