What is `mt=8` in iTunes links for the App Store?
HyperlinkApp StoreItunesHyperlink Problem Overview
Does anyone know the significance of the mt parameter in App Store Links?
Sample link:
http://phobos.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=337319445&mt=8
It seems that any value will work, like mt=0, mt=999, etc.

Apple designates a number of different Media Types (mt values):
1 Music
2 Podcasts
3 Audiobooks
4 TV Shows
5 Music Videos
6 Movies
7 iPod Games
8 Mobile Software Applications
9 Ringtones
10 iTunes U
11 E-Books
12 Desktop Apps
So, to answer your question, the "mt=8" in iTunes links simply identifies it as being of type 'Mobile Software Applications'.

Some people noted the you can actually drop the mt part of the link and you still end up on the expected page. This is correct, but on iOS it is helpful to attach the mt tag to tell the OS to what app to switch. When you don't add the mt part and you link to an app the OS will first fire up the iTunes app. This one then figures out that the link points to an app and then switches over to the App Store app.
Therefore it is good practice to enhance the experience for the user by adding the correct mt tag to your iTunes URLs.

This is a value to help you determine (or set) the “campaign” of the link (similar to the “Enhanced Publisher Interface” from Tradedoubler or the “Signature Tracking” from LinkShare). With GeoRiot, this parameter is set with the TRACK parameter and is synonymous with “Tracking Tag”. > >TDUID – TradeDoubler Unique Identifier: This is used for affiliate links that skip the TradeDoubler redirect. For those links, this value is consistent per account but needs to be set up with Tradedoubler in advance. > >partnerId: Previously used to identify each of the original affiliate networks, but currently only used for TradeDoubler, which has an ID of 2003. Note that the capitalization of this parameter is important. > >affId – Affiliate ID: After a Tradedoubler link is processed via their redirect the final link will include the affid parameter. The value included will be the same as the “a” value in the original Tradedoubler affiliate link that was resolved.

The mt = Media Type. mt=8 == media=software
Valid media types are : movie, podcast, music, musicVideo, audiobook, shortFilm, tvShow, software, all
presumably, movie = 1, podcast=2, music=3, musicVideo=4 and so on until software=8
I think anything other numeric value (>8) than those valid ones will return all.

I USED to think you could strip the mt and ls parameters without any impact.
I just discovered a case where that failed... it worked find on iPhones without the parameters but not on iPads. On an iPad it launched iTunes, but never brought you to the right app.
I'm not sure why... but, I put them back in and it works fine on iPhone and iPad.
I didn't experiment with stripping just the mt vs. the ls. I suspect it's the ls=1 that is the culprit... though I'm not sure why iPhone would be more forgiving than iPad.

The app on Appstore has specific URL format http://itunes.apple.com/[country-code]/app/[app-name]/id+[id_value]?mt=[1...12]
-
country-code can be us for united states, in for india etc
-
mt stands for Media Type
-
Value for mt can be anything from 1 to 12 and each assigned to specific category
i. 8 for iOS apps
ii. 12 for Mac apps

When you've got a unique id already like: itunes.apple.com/us/app/rogo/id400118698?mt=8
it seems to work fine without it, ie: http://itunes.apple.com/us/app/rogo/id400118698
In this new URL format, only the id matters - the app name "rogo" is ignored.

Note that some browsers will respect preferences for handling different media types -- ie it can have unintended/unexpected consequences if you strip it.
