For a complete and detailed analysis of an already conducted advertising campaign, you can use the Hybrid Query builder. This tool will allow you to build reports on any statistical slices. You can specify the parameter which you need for analysis, such as time, inventory, device, ad networks, ads, city, gender, device type, and then apply the desired filter. For example, you can see the number of impressions/clicks / CTR, etc. by type of user device in the Google Network over the last week.
At the moment, the time interval for which you can see statistics in the Query Designer is limited to 3 months.
* This tool is available in the accounts of advertising agencies.
