Now I have an idea.. Let's say we have an app in our Play Store. It's paid (let's say it's 10 TL. Google Play takes 30% of each download, leaving me with a net of 7 TL). Now I'm going to run AdWords ads for this app. App ads deduct money per download based on the budget you allocate. Now I set the cost per install (CPI) for my app at 0.50 TL and start my campaign. Now, Google will charge 50 kr? per download for my ad. Let's say 100 people came from the ads and I stopped the campaign. I spent 50 TL on advertising with 100*0.50 = 50 TL, which means 100 people purchased the app. This equals 100*7 TL = 700 TL earned. After deducting 50 TL ad expenses, I have 650 TL left. Investing 50 TL to earn 650 TL seems very logical, doesn't it? Of course, this is just my imagination, I haven't tried something like this before My question is; does such a thing really exist or is it not working out as intended? ???? I would greatly appreciate it if you could answer.
