Idea 4: Cross-Promote Through Social Media
Social media sites such as Facebook and Twitter can help you stay engaged with your customers who use your app. Facebook allows you to showcase your app, provide videos of your app, announce contests, address support concerns, and gather customer feedback. You can generate a significant following for your app, and use this captive audience to promote your app and announce updates.
More likes beget more likes as well. Having a huge community of faithful users will keep your app in front of your customers and prospective customers. Twitter can also be used to announce updates, offer tips and advice, and promote updates.
