What is “shortened URL”?

What is a shortened URL? It’s literally a “short URL of a long string”.

For example, when you’re trying to tweet an Amazon product page on Twitter, have you ever been surprised at how long the copied URL was?

Some websites have long URLs, which can be annoying if you try to paste them directly into Twitter or email (* In the case of Twitter, the URL is currently shortened automatically).

Short URLs are useful in such cases.

By shortening the URL, you can save the SNS posting space and use the limited number of characters effectively.

Some examples of URLs that have actually been shortened include:


Recently, many services such as Twitter automatically shorten the URL, but if you want to shorten a long URL by yourself, you can use a URL shortening service such as Bitly.
