Very good article! I learned a lot from you. Sometimes we just have to think about monetizing differently. I always suggest people just don’t depend on admob or paid app to get revenue from an app.

If you have an app and that has pretty much user, you can always sell affiliate product through your app and make money.

I have an app that has 30k+ downloads within 7 months and now has 10k+ active users. With this large number of audience, i could easily pick some affiliate product that is relevant to my app and show a pop up as ad.

Your app was traveling listing, you could add some traveling gear from affiliate program to your app and you could always make money from it. As your all audiences are traveler there is higher possibility to sell your affiliate traveling products higher cause you’re exactly showing ad to those people who are interested in traveling!!
