You can customize the metrics that appear in the campaign performance table of your Quora Ads Manager by clicking the “Configure Columns” button at the top right of the performance table.
From there, you have the option to select (and deselect) which metrics you want to appear, as below:
What are the differences between Clickthrough and Viewthrough conversions?
A Clickthrough Conversion is when a user clicks on your ad and completes the conversion action associated with your campaign within 28 days after clicking on your ad or your custom conversion window.
A Viewthrough Conversion is when a user converts on your campaign objective within 1 day of viewing your ad. In other words, a Viewthrough Conversion happens whenever your ad generates an impression, no click, and the user who saw the ad converts within 1 day or your custom conversion window.
