can i add adsens ads in download page eg. https://davshort.ooo/index.php/s/aQK6YtxySsSLxGB
someone have the idea? if not how i can earn? is there any subscription system?
nope. But you can insert it in the html layer in that view. So under the download button can be adds
Addition:
In your case you don´t have an imprint on your webside. When you earn money with adds it is better to have one.
Don’t do this, otherwise you could loose your AdSense account.
Wordpress is well suited
