What is permalink?

I recently observed that many sites, especially ones with dynamic content in their home page that would change over a period of time, have something called permalink appearing under the content. Here is what a permalink is.

Permalink is a shortened version of "permanent link." In case of sites like blogs, news, etc. the location of the content gets moved here and there. For e.g. on the day it appears, it is placed in the home page, but after a period of time it gets moved to archive. This creates a problem who refer to the content using the parent URL. To circumvent this problem, when the content is created itself, its given a URL ("link") which wouldn't change over a period of time. And using this link, you can refer to the content anytime you want.

Henceforth, when you forward any URLs, make sure you forward the permalink if one is present. This way one will not be surprised by some irrelevant content when they click on the link after a long time.

There is a good article about permalink here.
