Approximate previews
Each app crops and caches previews its own way. These mockups follow their usual layouts; the real result can differ.

One link for all your links
A VISU Link page comes with its own sharing preview already set up, so the link you put in your bio shows a clean title and image when people share it.
Create a free VISU LinkHow to use it
- Paste the full address of the page you are going to share.
- Look at the previews to see how the title, text and image come out.
- Fix what the audit flags in your site or CMS (often an SEO plugin field).
- After fixing, run the check again. Apps keep old previews cached for a while.
Examples
Before posting an article
Make sure the image is not cropped and the title is not cut off in WhatsApp groups.
A link that shows the wrong image
Check whether og:image points to the right picture and if it loads over https.
Questions
What is Open Graph?
A set of meta tags (og:title, og:description, og:image and others) that tell apps what to show when a link is shared. Twitter cards are X’s version, with Open Graph as the fallback.
Why does WhatsApp still show the old preview?
Apps cache previews. WhatsApp usually picks up changes for new messages after some time; Facebook and LinkedIn have their own refresh tools (Sharing Debugger and Post Inspector).
What image size works best?
1200 × 630 pixels (1.91:1), JPG or PNG over https, works on Facebook, LinkedIn and X. For WhatsApp, also keep the file light: images above roughly 300 KB often show no picture there.
Why can some pages not be checked?
The checker fetches the public page from our server. Pages behind a login, on private networks, or that block automated visits cannot be read.
