What are the differences between clickthrough and viewthrough conversions?
Clickthrough and viewthrough metrics are measured through the Quora Pixel.
Clickthrough conversions are measured when a user clicks your Quora ad and performs a conversion event within 28 days of clicking the ad. Therefore, the default attribution window for clickthrough conversions is 28 days.
Viewthrough conversions are measured when a user views your Quora ad and performs a conversion event within 1 day of seeing the ad. In this case, they did not click on your ad. The attribution window for viewthrough conversions is 1 day.
For more information, please see Conversion Metrics. If you would like to change your attribution windows, please see Can I change the clickthrough or viewthrough conversion windows?
