iTunes Connect now has keywords
Apple have added an extra attribute to applications on iTunes store – keywords.
You can configure your keywords with the “Edit Information” link against the application. SendIt4.me (iTMS) has already been updated 
Be careful though. It appears you can only update your keywords ONCE per application update – so make sure you choose the right ones the first time around – otherwise you’ll have to go through the painful approvals process to get it corrected.
The keywords should help with searching for your application within the store. Fingers crossed.
— EDIT —
You can also only have up to 100 characters for the keywords. Don’t get caught out! If you submit with more than 100, it tells you too late – you’ll have to resubmit your app to fix it.
