What does “converted clicks” measure?
- The total number of clicks within your chosen conversion window
- The total number of conversions divided by the total number of clicks
- The total number of clicks that led to a conversion
- The percentage of clicks that led to a conversion
“Converted clicks” is actually a click metric. It counts the number of clicks that lead to one or more conversions. For example, if a customer clicks your ad once and then completes two different conversions, “Converted clicks” only counts the one click. You might use this metric if you’re tracking multiple types of leads and are interested in seeing clicks that result in one or more leads (regardless of the conversion action).
The “Converted clicks” column shows you the number of AdWords ad clicks resulting in one or more conversions within your chosen conversion window.
