Friendlier URLs

I dislike the effect of ls=1 (launch App Store.app or iTunes.app) so I never share URLs in that format – I habitually remove that part of the URL.

I also habitually remove parts such as ?mt=8 and ?mt=12 – they seem superfluous. So for example:

Questions

Does either ?mt=8 or ?mt=12 add value to the end user?

If not to the end user, how do those things add value?

MT stands for media type. You can find known values in the answer to similar question.

Because there’s usually an ID in URL, it may seem odd, but according to another answer to that same question, the mt query parameter helps the operating system to launch the right store in the right app. For example on iOS, you may see sometimes that links open the iTunes app first and then the iBookstore in the iBooks app. Other times, the iBookstore is opened right away. That is why mt should be part of iTunes and why you should probably use iTunes Link Maker.

There's an annoyance with iTunes Link Maker: its URLs for Mac apps differ from the URLs that are seen when links are followed … but I blame these discrepancies on Apple. This is a great answer. – Graham Perrin May 5 '13 at 3:38
