Why does Twitter have its own link shortener?
- Shortened links allow you to share long URLs in a Tweet while maintaining the maximum number of characters for your message.
- 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 Tweet is when compared to similar Tweets.
- Having a link shortener protects users from malicious sites that engage in spreading malware, phishing attacks, and other harmful activity. A link converted by Twitter’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.
