<p data-start="7632" data-end="8060">My ROI on youtube ads was awful for months&mdash;I kept losing money. PowerAdSpy changed that. By studying which ads in my niche had been running successfully, I cut out weak ideas and focused on proven strategies. Finally, my campaigns turned profitable. It&rsquo;s such a relief after endless trial and error. Do you think ROI improvement comes more from research or just constant testing?
