Best ways how to promote your app...

1. Build a microsite. This one or two-pager showcases your app to the web audience. Take cues from Snapchat and Path.

2. Build a teaser website. Do this a month or two before your launch to collect email addresses of people who would like to know when the app launches.

3. Start a blog. Attach it to your microsite. Write interesting content that will draw people to your website. Buffer app does this really effectively.

4. Share your content. Use your Twitter, Facebook, Google+ and LinkedIn profiles to promote the app several times in a week.

5. Create a product video. Make it creative, funny, thought-provoking or personal. Tell the story, but in a way people can identify with. Here's a great one as example from the Dollar Shave Club.

6. Get press, tons of it. Entrepreneur Neil Patel says: "Press is the best way to kick start your startup, and the best way to get it is to manually reach out to journalists."

7. Pitch to app review websites. Sites like 148apps, AppStoreApps and AppAdvice can generate a lot of buzz for your app if they mention it.

8. Contact bloggers who would care. Identify bloggers who write on niches that relate to your app. For instance, a children's app can be pitched to bloggers write write for mothers.

9. Apply for awards. Look into awards such as the Kiip Build Fund or The Mobileys. If you win, you also get a ton of press, not to mention winner's booty.

10. Start a podcast. Publish it on iTunes or your own website. Draw content from the niche your app caters to most.

11. Always be collecting emails. Gather potential customer emails through Facebook, Twitter or your website. An email list of people who have opted in is a powerful marketing tool.

16. Run a contest. For example, you can encourage people to tweet and share content on their social networks promoting your app. A random person every week can win a promo code to download your app for free if it is a paid one.

17. Create a Facebook group. Form a group for people with common interests related to your app's niche so they can meet and socialize regularly. If your app caters to hikers, for example, create a hiking group.

18. Get speaking opportunities. Research events that touch on the topic your app addresses and make an appearance. Start small and get recognized as an authority in the space.

19. Take advantage of voicemail. Include a creative mention of your app in your phone's voicemail recording.

23. Optimize your email signature. Provide a catchy one-liner about your app along with the link to download it in your email signature.

24. Consider offering a promotional price. If your app is a pay-to-download one, consider a promotional pricing of $0.99 during the launch time. This price point encourages impulse purchases.
