Hi,
I have an AdWords account with several campaigns. I want to migrate all of them to the upgraded URLs using strategy 3 because their custom parameters change regularly. From the migration tutorial, I understand that I should implement the tracking template on the campaign/adgroup/ ad level and then delete and recreate each and every ad (because I can't use UpgradeAdUrl). Now for my questions:
1. if I want to specify the custom parameters for each ad separately (in the ad level) - when should I do it? When I recreate the add? and how? - because AdGroupAd doesn't have urlCustomParameters, so should I add the custom parameters to the new ad object?
2. Where should I specify the tracking template if I want it to be on the ad level also?
3. After I upgraded the URL, I want to change the custom parameters in the ad level from time to time, should I delete and recreate my ad again? because if so, what is the big advantage of this strategy if I can't change my custom parameters regularly? If not, how can I do it?
Thanks a lot,
Ofir
