Paste a link to see how it looks when shared on WhatsApp, Facebook, X and LinkedIn, and get a list of what to fix. No account needed.
Any public page: your website, a product, a blog post or your bio link page.
We read the page's share tags the way an app does when you paste a link, and show roughly how each app will display it.
Each item says what to add to the page. Apps keep old previews for a while, so a fix can take time to show in places you already shared.
When you paste a link, the app reads a few tags from the page: a title (og:title), a short description (og:description) and an image (og:image). A clear title, one sentence about the page and a 1200 × 630 image make the difference between a preview people tap and a bare address they scroll past.
X also reads twitter:card. Set it to summary_large_image to get the large image instead of a small square.
Apps save a copy of a link's preview the first time it is shared and reuse it for a while. After you fix the tags, new shares pick up the change sooner than old ones. Facebook and LinkedIn have their own tools to refresh a saved preview.
Every bio link page on linkthe.app comes with a title, a description and a share image from your photo or cover, and you can edit the title and description in the SEO tab.
