For those of you who manage Google Ads, here is a pretty nice tool I was turned on to.
Google Ads Editor by Google: https://ads.google.com/home/tools/ads-editor/
It's an app for the Mac, which is kinda nice.
I have a client that I needed to move all ad groups to be under one campaign, and I was able to do so by simply cutting and pasting from one campaign into another. Super easy!
This is also good for you to be able to work offline on the ads and post the changes when you're ready for them to take effect.
