Google Discovery ads are visually engaging, personalized ads that appear in Google's feeds on the YouTube app, the Google app, and the Gmail app.They reach google audiences ready to discover new products/services. Using customer intent signals, Google uses machine learning to determine when users are most likely to engage with a brand. Some of the benefits I have seen - 1. Automated campaign settings for bidding and targeting so you can focus on optimizing campaign performance. 2. Targeted by audiences, not keywords. Google gives you many filters, including remarketing, detailed demographics, in-market audiences, life events, and affinity and custom intent. 3. Target ROAS: Google analyzes the value of a potential conversion every time a user searches for your products or services. With respect to that value, your bids are automatically adjusted to those searches, maximizing ROI. 4. Focused on conversions with bidding strategies like Maximize Conversions or CPA Target. 5. Can be created from one image or a carousel of up to 10 images, which can be square, horizontal or vertical. No carousel option in display ads. 6. Unlike display ads, discovery ads allows inclusion of lead forms in Gmail ads Some of my recommendations to get the best results - 1. Allocate high daily budgets (10x CPA value) 2. Use the Google Ads simulators for bids and budgets to analyze how the weekly performance of your ads can change with different strategies. 3. Allow time for campaign optimization (3 weeks to 3 months). Wait until you have at least 40 conversions in your ad group before making any changes. 4. Limit bidding changes to maximum 20% when modifying target CPA 5. Advertisers that combine retargeting and prospecting audiences can achieve 81% higher conversion rates and 25% lower CPAs. 6. Start with low funnel audiences and then enable automation with optimized targeting. Start by including 10-15 keywords in your custom audiences to impact google searchers of those terms. You can also expand audiences by using your online and offline data to re-engage existing customers or others who interacted with your company. Consider Similar Audiences for additional customers. 7. Include at least 3 images of each type (square, horizontal, vertical) and diverse headlines/descriptions. With a variety of images and texts you will allow the system to learn which compositions get better results. 8. Do not include low quality assets, remember that the minimum is 1200 x 68 to follow google guidelines. You can check that all assets are approved in the asset report. 9. Optimize descriptions with length, specificity, directness, call to action, and offers 10. Keep ads mobile-friendly
