Editing display network image ad destination URLs
I'm working on a site that has just switch from http to https.
It was easy to use the bulk change tool to update the text ads. However, there are also approximately 3,000 display image ads I need to update.
I tried exporting to CSV with Adwords Editor, find and replace. But when I tried to import the CSV back into Adwords Editor, i got a lot of errors like:
- The same campaign is specified more than once, with conflicting settings. Only the first occurence has been applied.
- Duplicate image ad.
- The same sitelinks is specified more than once...
Can anyone suggest a method of bulk updating display network image ad URLs?
Or steer me in the right direction re the Adwords Editor issue?
