Don't Dismiss the Scroll: The Unavoidable ROI of Short-Form Video

Short-form video is the highest-performing content format for many marketers, delivering impressive return on investment. Formats like TikTok, Instagram Reels, and YouTube Shorts are essential for reaching audiences, particularly as traditional media channels in New Zealand contract. These platforms are favoured by algorithms and drive significant engagement.

Why Short-Form Video Matters Now in New Zealand

The media landscape in New Zealand is experiencing an unprecedented shift. With the decline of local media outlets, advertisers are increasingly dependent on platforms like Google and Meta, which already capture around 60% of the country's total ad spend. This concentration makes it vital to master the channels where consumer attention is highest. Short-form video thrives in this new "attention economy." The average digital ad only holds a viewer's focus for 1.3 seconds, making concise and engaging content crucial for making an impact. These platforms are built to deliver compelling messages quickly, fitting naturally into modern consumption habits.

From Vanity Metrics to Verifiable Commercial Outcomes

Many experienced marketers are rightly sceptical of platforms that seem to prioritise vanity metrics like likes and views. However, the data shows that short-form video has evolved into a powerful performance channel. In fact, social-first performance video now accounts for 54% of all programmatic video investment. The key is to measure success with commercial outcomes, not just engagement. A strategic approach focuses on metrics like cost per acquisition (CPA), return on ad spend (ROAS), and direct revenue. With social commerce expected to represent over 17% of online sales by 2026, these platforms offer a direct path from discovery to purchase. At D3, we plan paid social as part of a full media plan, ensuring its role is clearly defined, whether as a primary conversion driver or as a driver of audience consideration.

Choosing the Right Platform for Your Audience

While often grouped together, each short-form video platform serves a distinct purpose. Understanding their differences is key to allocating your media investment effectively.

  • TikTok: Best for raw, trend-driven content that connects with younger audiences (Gen Z and Millennials). Its algorithm excels at viral discovery, offering immense organic reach potential.
  • Instagram Reels: Ideal for higher-quality, visually appealing content that integrates with the broader Meta ecosystem. It is effective for lifestyle brands, e-commerce, and influencer collaborations.
  • YouTube Shorts: Leverages the power of the world's second-largest search engine. Shorts are excellent for educational or "how-to" content that can drive traffic to a brand's main YouTube channel or website.

Using AI to Scale Production Without Losing Quality

Producing a consistent stream of high-quality video content can be a significant challenge. While there is consumer scepticism about AI in advertising, using it as a tool can provide a competitive edge. AI can assist with research, drafting, and generating variations, which frees up strategists to focus on creative direction and quality control. This human-guided approach ensures that efficiency doesn't come at the cost of brand integrity.
