The Rise of TikTok Ads: How to Maximize ROAS in 2025

TikTok is no longer just the app of viral dance challenges and catchy soundbites—it’s an ecommerce powerhouse. With over 1.6 billion monthly active users globally, TikTok’s influence on shopping behaviors, particularly in the beauty, fashion, and health & wellness spaces, is undeniable.

As the founder of Rally, a digital marketing and ecommerce agency that has worked with leading brands in these industries, I’ve seen firsthand how leveraging TikTok ads can transform a brand’s bottom line.

Here’s how to craft high-performing TikTok ad campaigns in 2025 to maximize your ROAS (Return on Ad Spend) and make the most of the platform’s evolving ad formats.

Why TikTok Is a Must for Ecommerce in 2025

‍

TikTok’s influence on consumer buying decisions continues to skyrocket. Consider these recent stats:

• Beauty and Wellness: A study in 2024 found that TikTok helped people discover 23% of beauty products worldwide. Hashtags like #TikTokMadeMeBuyIt got over 60 billion views.
• Amazon Sales: TikTok's use of direct product links has caused a 30% increase in Amazon affiliate sales. This boost comes from influencers on the platform.
• Fashion: TikTok’s “Get Ready With Me” videos helped fashion sales referrals rise by 50% in 2024. Users are looking to creators for style ideas.

For ecommerce brands, TikTok provides a great chance to reach Gen Z and Millennials. These groups spend most of the money in these areas.

At Rally, we’ve helped beauty, fashion, and wellness brands harness TikTok’s potential to create scroll-stopping ads that convert. By understanding the nuances of TikTok’s culture, we’ve crafted campaigns that balance creativity and data-driven strategies. Here are the steps we recommend for brands looking to maximize conversion rates and ROAS on TikTok in 2025.

1. Leverage TikTok’s Native Features

‍

TikTok’s ad formats—from Spark Ads to Branded Effects—are designed to integrate seamlessly into the platform’s user experience. Here’s how to use them effectively:

• Spark Ads: These allow brands to boost organic content, like creator videos featuring your products. For example, we helped a beauty client achieve a 4x ROAS by amplifying a creator’s “how-to” skincare video that felt authentic and engaging.
• Shoppertainment: TikTok’s live shopping feature is a game-changer for wellness brands. By partnering with influencers who align with your brand values, you can drive direct conversions during live product demos.
• Branded Effects: For fashion brands, consider creating AR filters or stickers that let users virtually “try on” products. This interactive experience boosts engagement and purchase intent, driving revenue generated through TikTok campaigns.

2. Prioritize Short-Form Video Content

‍

TikTok thrives on short, engaging videos. To stand out, focus on:

• Hooks in the First 3 Seconds: Start your videos with a bold statement or eye-catching visuals to capture attention immediately. At Rally, we often test multiple hooks using tools like Motion App to identify what resonates best with your target audience.
• UGC (User-Generated Content): Authenticity reigns on TikTok. Collaborate with micro-influencers to produce relatable content, like unboxing videos or tutorials. For a wellness client, we saw a 20% lift in engagement by featuring creators demonstrating how to use their product in daily routines.
• Trending Sounds: Incorporate popular audio clips or music to align with TikTok’s dynamic trends. Be sure to adapt quickly; trends shift fast on the platform.

‍

3. Invest in Data-Driven Creative Testing

‍

Creative testing is at the core of any successful TikTok ad campaign. Here’s how we approach it:

• A/B Testing: Test variations of your ads—different captions, formats, and calls-to-action—to determine what drives the best performance.
• Dynamic Creative Optimization (DCO): By leveraging DCO, you can automatically deliver the best-performing combinations of headlines, visuals, and CTAs to maximize cost per click (CPC) efficiency.
• Real-Time Analytics: Using Motion App, we track performance metrics daily, allowing us to make rapid adjustments and double down on what works.

4. Focus on Community Building

‍

TikTok isn’t just a platform for ads—it’s a community. Brands that build relationships with their audience see higher engagement and loyalty.

• Engage in Comments: Respond to user comments on your ads to build rapport and increase the likelihood of conversions.
• Collaborate with Niche Creators: Partner with creators who have dedicated followings in your industry. For example, a fitness influencer promoting your wellness product will feel more authentic than a generic ad.

‍

5. Stay Agile with Trends

‍

TikTok trends are fleeting but powerful. Staying agile ensures your brand remains relevant:

• Trend Spotting: Dedicate time to identifying emerging trends on TikTok’s Discover page and tailoring your campaigns accordingly.
• Rapid Content Creation: At Rally, we’ve streamlined our process to produce TikTok-specific content within 48 hours, ensuring our clients never miss out on trending opportunities.
