You only really need this part:
As you have been told apple.com/iphone = www.amazon.com/dp/B09V3HZ8B5
The rest of what you posted on the Amazon link is tracking bullshit. Now, THAT is irrelevant !
Amazon product URLs are looong, but maybe people don't share them enough for Amazon to care. YouTube and Twitter put more effort into making them short.
So you could have urls like:
example.com?<a single icon>&productname=somethinghumanreadable
