“You will begin to see the new Google Ads brand—including the new name and logo—reflected in the product interface, Help Center, billing documents, and more. The URL you use to access your account will be changing from adwords.google.com to ads.google.com, and the Help Center will change from support.google.com/adwords tosupport.google.com/google-ads.”
What is happening behind the scenes isn’t changing much and the functionality will still be the same. As Google as grown and developed new ad products this change across Google AdWords and DoubleClick comes with the aim to help simplify things for advertisers to find the right Google products for their needs.
