I’ve been building web and mobile apps for many years. They were created to solve problems I had personally faced, but none of them became huge.After thinking about it for a while, I came to the conclusion that there were two primary reasons for that:1. Marketing: getting it in front of people 2. Demand validation: are people searching for it?And the combination has to be profitable.After a lot of thinking, I used Google Ads data for advertising costs and search volume, and created an interactive model based on those inputs, along with your costs and revenue.There is a walkthrough here: https://www.youtube.com/watch?v=JE-VbQ7HDYAAnd a real report here - No Login: https://ideas.trk7.app/shared/qS3PbOrrZo8oSeXZ7ef5m4KDyGiCOe...Let me know what you think :)
