what are the best possible ways to market a new upcoming social media application to get more traction , visibility and downloads world wide ?
I ask that when asking questions people provide adequate information to make a reasonably useful response possible.
What does the app do?
Who is the market?
What is the value to the user?
Who has the most to gain by using the app?
What is the business model?
Have you tested it? What were the responses?
Where are competitors marketing their apps?
I think you mean "paid" not "inorganic," right? You'll need to define what you mean by a social media application, because you might be talking about an independent app that acts like a social media channel, a plug-in for an existing social media channel, or a control program that lets users connect to existing social media channels. Precise language is going to be essential or viewers of your ads will not understand the relevance and therein not click through.
Aside from recommending A/B testing of ads, changing only one element at a time, and letting the ads run for at least two weeks before making further changes, it's hard to say which channels or what styles of advertising are most in-line with your target audience. Remember that strategy comes BEFORE tactics. Content rules, so organic traffic is ALWAYS better than paid traffic in terms of performance. That means you need a fully described product with persuasive language before you start advertising.
There are three things all advertising requires to persuade purchase behavior. 1) personal benefit, 2) dramatic difference, 3) reason to believe. Most companies can get #3, but fail on the other two. Not only does the description need to communicate benefits (not features), they need to be personal benefits, not general benefits. And when it comes to a difference, 20% different isn't enough to motivate most people to change behavior, you need to start exceeding 50% difference before you can expect real behavior change.
This means while you're developing your product, you need to make sure there is a clear personal benefit to its use, and that you are sufficiently different that you can be distinguished from others in a dramatic way. If you aren't different, you will constantly battle for attention and lose interest because there's not enough to motivate consumers to change their current behavior.
You can also have the greatest product ever, but if you don't describe it in compelling ways, it will also fall flat. Since you're still in development (upcoming is your word), you have all the time in the world to make sure it's something people will want and to develop your strategy to reach your target market. Forget the specific tactics for right now. Digital marketing is a single tactic, and it might not even be the best one for you. But until you research your market, you won't know if it's the right one.
