WP-Short.io is the easiest way to generate short links for your WordPress posts. It is a timesaving integration since you don’t need to copy a long link and manually shorten it on Short.io.
Specify an API key (you’ll find it in your Short.io account), identify the post types to create short links for, and forget about it! WP-Short.io automatically shortens URLs for WordPress posts.
After you finish writing a striking post, share it with your friends on social media.
Now, instead of a long URL, a short and automatically generated link is already waiting for you. Just copy and send it!
