How long do tinyurls last

This makes it easier to include the link in an email or Twitter post without it breaking or taking up too much space. Your link will not automatically expire, however, after you have created your new link you will be given an opportunity to set an expiration date for your link. Once the link is expired, any page requests for that link will be sent to a page explaining that the URL is no longer active.

Anyone can use tiny. You can create tiny. In addition, if the website is a UCSF partner site, you can also request it be added to the list. Here are some current examples of other domains allowed:. This may make them less likely to click through in the future. Use the full link and they can make an informed decision.

Some shortening services stop working either temporarily or permanently , or wind up on spam blocklists. Twitter's analytics page can show you how many people saw a specific tweet, how many engaged with it and in which way e. Facebook may not offer robust analytics on profiles, but it does on Facebook pages, showing post reach, engagement, and website clicks. Even LinkedIn shows you how many people viewed each of your updates. Between that, tools like WhoSharedMyLink , and various analytics options available for personal and business websites, analyzing data from URL shorteners is probably unnecessary.

Shortening URLs used to help you save precious characters on Twitter, but this is no longer the case. Posting shortened URLs does the opposite. With 4 characters that means about 15 million unique addresses. For something like Google Maps, I don't think that is very much and if you can't recycle, my guess is they run out of available addresses fairly quickly. Now for the part I don't get. While handing out addresses, they start to run out of unused addresses. They have to check if a newly generated address has not been issued yet.

The chance this has happened and the address is already in use increases. The straightforward solution of course is to generate a new URL over and over again until they find a free one or until they have generated all 1. However, this surely can't be how they actually do it, because this would be far too time-consuming. So how do they manage this? Also, there are probably several visitors at once asking for a short URL, so they must have some synchronization going on as well.

But how should the situation be managed when the fifth character needs to be added? None of them will ever be used. However, when Google would strictly enforce the policy of URLs not expiring once issued, this means that there are lots and lots of dormant URLs in the system. Again, I assume Google and the other services as well have come up with a solution to this problem as well. I could imagine a clean up service which recycle URLs which have not been visited in the first 48 hours after creation or less then 10 times in the first week.

I hope someone can shed some light on this issue as well. Does anyone know how the problems mentioned above might be resolved and are there any other problems?

Ok, so this blog post sheds some light on things. These services don't randomly generate anything. They rely on the underlying database's auto-increment functionality and apply a simple conversion on the resulting id. That eliminates the need to check if an id already exists it doesn't and the database handles synchronization. That still leaves one of my three questions unanswered.
