Before using PowerAdSpy, I was spending money blindly, unsure which creatives would succeed. By analyzing top competitors, I learned that the most effective <strong data-start="3189" data-end="3204">display ads were simple, targeted, and visually consistent. Applying these principles, I started seeing higher CTR, lower CPC, and improved conversions. My overall ROI improved dramatically because I could make data-backed decisions instead of guessing. PowerAdSpy transformed my campaigns from trial-and-error to systematic optimization. Do you rely on competitor insights to improve ROI for your display ads, or do you primarily experiment on your own?
