A new version of AdWords Editor, with a refreshed design, is now available for all advertisers globally. You’ll find it even easier to manage your campaigns at scale with custom rules, faster account downloads and more.

Custom rules help you build high-performing campaigns

With AdWords Editor 12, you can now use custom rules to check for changes that don’t align with your best practices. For example, our best practices suggest showing search ads with four or more sitelinks. When you use this rule, AdWords Editor will let you know which campaigns or ad groups don’t meet this best practice before you post changes. You can get started by using our recommended rules, or create custom rules based on your own best practices.

Faster account downloads for new AdWords Editor versions

To reduce the time you spend waiting for your accounts to download after you update AdWords Editor, we’ll now transfer more of your data from previous versions.

A new look and feel

You’ll also see a new design that better aligns with Google’s commitment to material design. While the changes will be subtle and won’t affect how you manage your accounts, you’ll now have a more cohesive visual experience across AdWords Editor, the new AdWords experience, and other Google products.

and more …

The new version of AdWords Editor also supports bidding to maximize conversions, uploading up to 20 images and videos for Universal App Campaigns, and using the new customization fields for responsive ads.
