Google just released the ability to track conversions for up to 90 days in AdWords. Previously conversion were only tracked for a set 30 day window. Now you can select from 7 to 90 days, depending on what fits well with your tracking goals.
Here’s how…
Go to AdWords –> Tools & Analysis –> Conversions. In the table listing your conversions you will see a new column called ‘Conversion Window.’ Click on the conversion window and you can edit it inline.
You will need to have conversion tracking set up for this to work.
