At YouTube, we focus on helping advertisers maximize their return on investment by leveraging the interests and feedback of our viewers. High quality ads that deliver an optimal viewer experience are more competitive in the auction, and will likely maximize ad performance over time, because our system prioritizes providing positive viewer experiences.
How ad quality is determined
Viewer feedback is the primary driver of ad quality. YouTube continuously analyzes user engagement and feedback signals (such as blocking or reporting an ad), alongside automated systems and ongoing audience research, to understand what elements disrupt or enhance the viewing experience - which ultimately leads to an overall quality evaluation. This ensures that viewer preferences and expectations are heard, and consistently considered as they evolve over time.
Impact on delivery and reach
Higher quality ads generally perform better in the auction due to the trust they build with users. Ads with lower quality tend to cost more per impression, which can reduce their distribution and possibly lead to a lower return on investment.
Ad quality considerations
YouTube continuously analyzes user engagement feedback signals to understand viewer expectations, which are dynamic and constantly evolving. The following non-exhaustive list of patterns are a few considerations when thinking about your audience:
- Smooth vs. disruptive pacing and audio: While sudden spikes in volume or rapid, disorienting cuts can feel jarring to viewers, steady audio levels and natural, well-paced transitions can keep audiences comfortably engaged.
- Credible vs. unrealistic claims: Data shows that ads making improbable claims or promises, such as guaranteed outcomes, often erode audience trust, whereas transparent, verifiable claims and realistic expectations tend to build lasting credibility.
- Inviting vs. uncomfortable visual content: Visuals that startle or disturb viewers can lead to negative responses, while approachable imagery that resonates naturally with your audience can create positive reception.
Consider avoiding these patterns and other similar attributes to help improve viewer engagement. Focusing on clear, transparent messaging with thoughtful design will help increase the odds that your ads will resonate with your audiences, and maximize your performance across YouTube.
