How Did I Optimize My AdWords ROAS with the Data Analytics Tool?

In the past, my ROAS in my Google ADS ads was constantly at 400%. I looked for various ways to increase this. Although the quality score of my ads was 10/10, I could not increase my ROAS. But then I started doing data analysis. I started applying my analysis and managed to increase my ROAS to 450%. Later, I came across https://app.heybooster.ai and started to optimize my campaigns in line with the instights I got from here. Now my ROAS is 600% and I am very happy. Do you guys use the analytics tool? If you are using which one do you use?
