Ans:- Optimise targeting in Google Ads is a function that utilises machine learning to automatically update your ad targeting parameters in order to increase campaign success. This feature is intended to assist advertisers in maximising their return on investment (ROI) by displaying adverts to the most appropriate audience based on their behaviour and preferences.
Google Ads analyses data from your campaigns, including as search queries, keywords, locations, devices, and demographics, to find trends and insights about your audience when you use optimise targeting. It then utilises this information to make real-time changes to your targeting parameters, such as modifying bids, broadening or restricting targeting possibilities, or omitting certain populations.
