A month ago, Google told us they are rebranding AdWords to Google Ads after 17+ years of using the brand name AdWords for their search ad product. That has happened as of this morning. When you go to adwords.google.com you are now redirected to ads.google.com and the AdWords logo and branding is gone.
The Google AdWords Twitter account at @AdWords is dead, it has been moved to @GoogleAds. Google did post about this on their new Twitter feed:
Today is a historic day – although not much is changing right now outside of the brand.
