I have 2 campaigns setup ..... one campaign is to count the number of users filling up a form on the landing page and the other campaign is to count the number of users downloading the software. How many conversion codes do I have to create? Why? If I create 2 conversion codes then what will be the change between the conversion codes?
You need to create two conversions, one for the form and another for the download action. You will see the actions tracked separately in AdWords. The difference between the codes will be the conversion label.
Hope this helps.
