Amazon Affiliate Link Shortener
This is a tiny tool I had built for myself back in 2015, which I had made public in case it could also help others.
The concept is rather simple: you give it an Amazon affiliate link, and it outputs a shorter version of it.
How did it work?
It was actually really quite simple.
In order to work, your affiliate link requires two things: the product ID, and your affiliate tag. However, the affiliate link that Amazon generates automatically contained a lot more information (mainly for tracking and analytics purposes), which isn't absolutely necessary.
What this link shortener did was remove all of this "unnecessary" information from your link, resulting in a much cleaner link.
Where is it now?
The tool is no longer available today.
