Turning Underperforming TikTok Ads Into 5X ROAS for a Fashion E-commerce Brand
A growing fashion e-commerce brand came to us with a familiar split. Their Meta campaigns delivered moderate, reliable returns. Their TikTok ads did not. Spend went up, engagement stayed flat, and conversions trickled in. We took over the TikTok account, rebuilt it around how the platform actually works, and kept it aligned with Meta so the brand read as one company everywhere shoppers found it.
Channels: TikTok Ads, with Meta alignment · Industry: Fashion E-commerce
The Problem
TikTok was the weak link. The brand was already running paid social on Meta with steady results, but its TikTok ads carried high costs, low engagement, and few conversions. Return on ad spend sat at 2X and would not move.
The core issue was creative. The team had been repurposing Instagram assets straight onto TikTok. Polished, static, and built for a different feed, those creatives did not match the pace or tone TikTok users expect, so people scrolled past.
Targeting was broad and untested. Audiences were loosely defined, and there was no structured testing to show which segments or hooks actually drove sales.
Messaging drifted between platforms. What a shopper saw on TikTok did not line up with what they saw on Meta, which weakened the brand and made every touchpoint work harder than it should have.
What We Built
TikTok-native creative
We stopped recycling Instagram assets and produced creative made for TikTok. That meant working with the platform's trending formats, native pacing, and sound-on viewing instead of forcing a static feed ad into a video slot. The goal was ads that felt like content rather than interruptions.
Sharper audience targeting
We rebuilt the audience strategy from broad guesses into refined demographic and interest segments. Narrowing who saw each ad meant spend went toward the people most likely to buy, which brought costs down and raised relevance.
A/B testing discipline
Every assumption went into a test. We ran structured A/B tests across hooks, formats, and audiences so decisions were driven by what converted, not by opinion. Winners scaled, losers were cut, and the account kept improving on evidence.
One message across TikTok and Meta
We aligned creative and messaging across TikTok and Meta so the two channels reinforced each other. A shopper who met the brand on TikTok and later saw it on Meta got a consistent identity, which built trust and made the whole funnel more efficient.
The Results
The rebuild changed the numbers that mattered. TikTok went from the account we were propping up to one that carried its weight.
ROAS climbed from 2X to 5X
Return on ad spend more than doubled, rising from 2X to 5X. Creative that matched the platform, paired with tighter targeting, turned the same budget into far more revenue.
Acquisition costs came down
Better targeting and stronger creative meant fewer wasted impressions. Customer acquisition costs dropped as spend concentrated on audiences that actually converted.
Conversion rate improved
The higher conversion rate was the engine behind the ROAS gain. Ads that spoke to the right people in TikTok's own language turned more clicks into purchases.
Brand identity unified across channels
With messaging aligned across TikTok and Meta, the brand stopped sending mixed signals. One consistent identity across both platforms strengthened recognition and reinforced every campaign.
Key Takeaway
Underperforming TikTok ads are rarely a platform problem. They are usually a creative and consistency problem. By building for how TikTok works and keeping the brand aligned with Meta, we moved this fashion e-commerce brand from a 2X account to a 5X one, cut acquisition costs, and gave shoppers one brand to recognize wherever they found it. If your TikTok spend is not returning what Meta does, the fix usually starts with the creative.
