Whether you’re a developer or a marketer, Facebook offers a huge and most powerful option to create engaging experiences with your target audience on Facebook. There are plenty of third-party applications that have already been built on the Platform APIs–many of which have allowed for new forms of brand and product interaction, and many of which turned out to be nothing more than lame ad delivery vehicles that failed to take the user’s experience into account.

So what makes a compelling application stuffed with all necessary elements to create a rocking user experience.

1. KISS(Keep It Simple Stupid)

Yes! The renowned SE rule applies here as well i.e. your app needs to be simple, make it hard for the user to interact with and the user’s going to make it hard on you by uninstalling your application and not recommending it to their friends. So a simple concept with a simple interface will beat out the application with the learning curve.

2. Love it? Share it! Marketing!

Plan your application around the power of the Facebook social graph which is the most powerful way of advertising known to man and it’s called drum-roll please: “word of mouth” advertising nothing more powerful than a friend telling you about something cool they just used and that they should try it out too. Incorporate all aspects of Facebook to acquire, engage, and keep users on your app on a daily basis, and lastly make your users essentially volunteer employees to spread your brand and company among the 60+ million users that login to Facebook on a daily basis.

3. Create a “thing-for-two”

Create something that involves more than one users. By doing this, you’ll already jump into marketing seat since users will share it with others. One will share with the other and so on.

4. Don’t Force Literally

Don’t make your application to force users to invite them rather make it interesting enough so that they share it automatically. You got to respect users if they want to keep application private for them and not to share with any of their friends. Although “word of mouth” advertising can do wonders but you can’t afford it at cost of user’s annoyance.

5. Abide By Facebook Policy

Finally, this is the first thing you should keep in view is to abide by the Facebook’s terms. Its the most important thing since many applications get blocked almost every day by Facebook due to violation of terms of service. So make sure you stay in the scene.
