✳️ TIPS | LINK PREVIEW ✳️
🌐 TELEGRAM LINK PREVIEW SYSTEM 🌐
‼️ The parsing/preview system is server-based, so it cannot work in Secret Chats. The parsing system is managed locally in secret chats. ‼️
➡️ All links to Twitter tweets, Instagram photos and YouTube videos are beautifully rendered so that you’ll see what the link is all about before opening it.Once you paste a URL to the message input field, Telegram will start analyzing the link and getting a preview for it. If you prefer to send a particular message without the preview, just tap the x to remove it.

❓How does Link Preview technically work?
➡️Link Preview is generated server-side. Means, that users send the link to the server, server is fetching infos via API, creates a rich text preview and sends it back to the user. IP of server is shown to the API, not the IP address of the user.
___________________________
❓ Optimizing web pages to work with Link Preview
➡️ Telegram is using the Open Graph protocol (
http://ogp.me/), so it's very easy to update existing web pages to support rich link summaries. Make sure that you can edit the source code of your website and add some <meta> tags in the <head>.
og:title: The title of your object as it should appear within the graph, e.g., "Test Title".
og:description: A one to two sentence description of your object.
___________________________
‼️ Make sure you do not block access to your website. The robots noindex meta tag forbids the Telegram server to fetch information from your website. If you did it once, the Telegram server will remember that it's forbidden to fetch it. This may change in the future. But for now, you would need to change your URL.
