What should an ideal link shortener have?

Question

Link Shortening

What functionality should an ideal link shortening service have? API, statistics, other?

Answer 1

1) Timer, at the end of which the link is killed
2) Ability to buy a link for yourself 3) Preview for pdf, doc, xls ,
jpg, etc. balls and issuing a link can be continued for a long time

Answer 2

0. The goal is to live, and not die after six months of work. Since the era of the popularity of shortcuts, not everyone has survived.
1. Short domain, although shorter than j.mp and t.co is no longer possible.
2. Statistics.
3. Custom addresses and domains (domains can be paid, but more functionality is desirable there).
4. Simple API and preferably compatible with existing popular ones, for example bit.ly, to take their library, change the domain to yours and it all worked.
5. Clients/additions to mobile axes and browsers.
... The ability to set the lifetime of a link, access to it by password/key/retina, I do not consider it very important for a public service.
... You can make the functionality of creating a set of links, for example, in the form of tiles.
@lookidI wrote above about file sharing and preview, but it seems to me that this is already beyond the scope of the cutter as such.
