Responsive search ads on Google use machine learning to optimise their performance. Advertisers write multiple headlines and descriptions for one ad, and then Google displays these in different combinations when the ad is triggered. Using machine learning, Google tests the combinations and determines which ones are most likely to achieve the advertiser's goals. This should lead to improved optimisation and performance, and can ultimately help boost conversions. This video explains why you should let machine learning optimise your Google responsive search ads and how we do this at Webcertain.
