Is have spent more than $1,000,000 over few years for ads - how can I use the data?

[Fafa]

I have spent more than $1,000,000 over last years promoting only 2 offers in different traffic sources and I still spend about $20,000 per month. What would you do with the data (good/bad ad zones etc.) to monetize it? Any ideas to squeeze more cash if I need to spend money every month to
