What is the difference between link and rich type in oEmbed?

Question

I would like to add embed info to my site using oEmbed tag. I am confused between link type and rich type on which context I should use both.

Here is the oEmbed documentation link which doesn't make me clear.

Any advice in this regard is much appreciated ! Thanks in advance :-)

Answer 1

Link type can be used when you wish to provide generic meta data about the url title, author_name etc... without providing html content or url associated with the requested url

Rich type can be used when you would like to provide html content (which could be embedded within external sites) along with width and height of the iframe.
