Google Ads manager

Hi, my ask is simple. I have worked at DSP side i.e dv360. I am looking to learn SSP side i.e GAM ( Google ads manager). If you are someone who can explain end to end campaign structure and each entity of GAM in detail. Please get in touch with me. I am looking to hire someone on freelance basis. Your content should be cleaned and straight to the point. You should be able to make a candidate ready to be able to attend SSP side interview and be able to clear the online certification too. Thanks
