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.
