If I put a link on a comment on Twitter, facebook and other place the website analyse the link and show a small preview of the link if possible. It could be a small player for a video or an image with a title, etc.
How does this work? Is there a standard request made to the site to get an embed version of the page?
How can I do this on my site so the links shared by my users get the best visibility possible?
I am using Django and my content is recipes: an image with a title would make great embed.
