One of your e-marketing PPC campaigns drives a lot of click and view-throughs, but has a low conversion rate. Analysis in Analytics 360 reveals that most users bounce immediately, but a certain segment who click on or view that ad (e.g. women aged 18-35) have a really high conversion rate. You refine the messaging and creative in your ads, adjust where these ads are served, and bid higher in order to find and attract more of this high-performing audience.
