‘Embed Link ShortCode’ tries to emulate the functionality that facebook has when a link is pasted to the input status. 
But it doesn’t happen when you paste a link in the body of a new post (as when you paste a youtube link in the visual view of a post), it’s done using a shortcode. 
The provided link to the shortcode is fetched to get the meta tags, and these meta tags are used to render the new post content. It tries to get an image and put it as 
post default thumbnail, and it uses some meta tags to get title text and to add a quote. The order in the post content is: image, quote and link. 
If you don’t like the HTML render, you can always edit the code to change format or suggest me some changes.
Usage:
1- Create a new post.
2- Add only the shortcode with the link (in HTML mode, not Visual) in the post body. For example:
[embedlink]http://example.com/example[/embedlink]
3- Push ‘Save Draft’.
If all is ok, the post content will be rewritten with the rendered html code. An image may be uploaded to the media library and added as post default thumbnail. 
 If nothing happens, click the preview link and some error message may be displayed. If a blank entry is showed, all is ok, then click Edit and you will see the rendered code. 
 Otherwise, it will be a bug: please, report it adding the URL you used and the plugin version (update to last version before report!).
4- Review the generated code.
<h3>Notes</h3>
