About X's link service (http://t.co)

Below are some frequently asked questions about t.co, X's link-shortening service.

How does link shortening work?


Links shared on X, including links shared in Direct Messages, will automatically be processed and shortened to an http://t.co link. Learn how to shorten links. Please note: anyone with a t.co shortened link will be able to navigate to the destination URL.

Why does X have its own link shortener?

  1. Shortened links allow you to share long URLs in a post while maintaining the maximum number of characters for your message.
  2. Our link service measures information such as how many times a link has been clicked, which is an important quality signal in determining how relevant and interesting each post is when compared to similar posts.
  3. Having a link shortener protects users from malicious sites that engage in spreading malware, phishing attacks, and other harmful activity. A link converted by X’s link service is checked against a list of potentially dangerous sites. Users are warned with the error message below when clicking on potentially harmful URLs. 

If the URL of a site you manage has been flagged, please see this help page about flagged URLs for more information.

Can I opt out of link shortening when I post links on X?

Because of the reasons listed above, X will shorten URLs you post on X. You cannot opt out of link shortening. 

Can I still use a URL shortener (like bit.ly) to shorten links?

If you want to shorten links to share with others, please see this help page on how to post links on X. You can continue to use a URL shortener to shorten links, and tracking metrics (like those from bit.ly) will continue to work as they did previously. The link service at http://t.co is only used on links posted on X and is not available as a general shortening service on other apps or sites.
