This aligns with what I’ve found in my campaigns. One more thing - testing responsive search ads alongside expanded text ads will give you even better results.
I completely agree with the answer above. Additionally, watch out for using the same ad copy across all ad groups instead of customizing. Many people miss this and waste budget.
Great question! Based on my experience, building custom audiences based on your best customers. This has helped me improve my impression share by 30%+.
