The search for a killer app is an on-going process. A killer app is one
that is accepted by most as the best in the market at that point of time.
List Of Attributes Of A Killer App
Facebook, Twitter, Google, Skype are some of the killer apps that took
off from the beginning they were launched. They all have hundreds of
millions of registered users logged on daily. With this kind of captive
audience, their websites become marketeers dream domains. That is
why their main income is from advertising space on their websites.
The following is a list of attributes that will benefit your app:
Most popular – widely accepted by everyone. Easy to use and
configure. They are the chosen app by virtue of design, uniqueness and
are usually free to encourage sign-ups.
No fees – sign-up or monthly. This is the only way to generate a user
database for any new app. If there is any fee imposed, the failure rate
of any new app is more than 99%. Most users can get free stuff on the
internet so charging a fee would tantamount to suicide by accident.
These apps do not sell any product on their website. Their objective is
to accumulate as much registered users as they can. When they have a
huge user base, they can then start selling advertising space on their
website.
