how to make a single word url link

Hi everyone,

Looking for some information or a plug in to create very short url’s, to be used on my website. I want to be able to create these url’s to track marketing efforts.

Example:

https://www.example.com.au/offer

https://www.example.com.au/promotion

https://www.example.com.au/workshop

How would I go about creating the offer/promotion/workshop url, and then have it redirect to a product or information page?

Thanks!
