You can view the conversion performance data from your Performance dashboard in greater detail from your Custom reports dashboard. Custom reports offer greater flexibility and allow you to create custom breakdowns so that you can analyse more specific groupings of your data.

For any custom report that you create, you can always select additional metrics that are relevant for your report, or you can apply any of the following pre-selected sets of metrics (presets):

• Performance: See how impressions, clicks and visits get credit for conversions, and how efficiently they performed.
• Conversion efficiency: See how efficiently your ads drove the interactions that you care about.
• Return on ad spend (ROAS): See how ads impact your bottom line and where you're getting the most value.
• Cost efficiency: See the cost of the interactions you care about.
• Reach: See how many people your ads are reaching.

To add any metrics as individual columns in your report, click Columns in the top right of your table to open the drop-down menu of metrics. You can either choose from Presets or individual Metrics.

Once you've created your custom report, you can view the data as a graph or table.
