Nowadays, thanks to tools like AppCreator24 app with no ads, anyone can create a mobile application and include advertising in it.
There are also tools to create websites, but there are already thousands of sites of all possible topics and, make a site that has many daily users, is very complex because great positioning knowledge is needed and, also, hopefully to appear in the first results of Google searches.
Instead, mobile apps is a world in expansion and it allows anyone to create an app and quickly get a high number of daily users and, consequently, earn money from advertising that we put in the app.
We need not worry at all to get advertisers to our app. You simply need to register with Admob, Appnext, etc. and these companies will give us a code to put in our app. From that moment our app will begin to show ads of different advertisers. Then these companies will pay you based on ads performance.
Obviously, as more users use our app, more money we'll make.
Therefore, to make money you need to create a mobile app and get as many users as possible.
AppCreator24.com allows to create many different types of apps but we need to create an app that is interesting to the greatest number of people possible and, at the same time, these users visit the app frequently. (So ads shown in the app will be seen more times and therefore you will make more money).
We recommend you to create an app where users can communicate with other users. This offers itself a dynamic content (which changes frequently) and causes users to access very often to see updates and actions of other users. The goal is to create a community of users (social network).
