What should be the structure of the website to retrieve information about the site in a telegram?

Some websites receive information in a telegram when they send a link, and on some websites they do not like this: enter image description here

So my question is: is there any structure for a website to download information in a telegram?

The Open Graph protocol allows any web page to become a rich object in social graphics such as Facebook, twitter, telegram, Skype and ...

As an example, below is the Open Graph protocol markup for The Rock on IMDB:

<html prefix="og: http://ogp.me/ns#">
<head>
<title>The Rock (1996)</title>
<meta property="og:title" content="The Rock" />
<meta property="og:type" content="video.movie" />
<meta property="og:url" content="http://www.imdb.com/title/tt0117500/" />
<meta property="og:image" content="http://ia.media-imdb.com/images/rock.jpg" />
...
</head>

Just use the meta tag with the name description:

<head>
<meta name='description' content="some content"/>
