When setting up your GDN campaign, you can choose your goal, whether that be increasing sales, generating leads, growing website traffic, or creating brand awareness. The metrics to measure your conversions would differ depending on your goal. If you want brand awareness, for instance, look at an increase in impressions and clicks. If you want more sales, then look at conversions and cost per conversion.
You can check the performance of your Google Display Network campaigns on the “Ads & extensions” and “Placements” pages with your Google Ads account. You can look at predefined reports that show basic metrics or create custom reports where you choose which data to show with charts and tables.
