How a TikTok Marketing Agency Scaled Our Sales 5X in 90 Days

In hyper-competitive online store markets with escalating cost of acquiring customers and declining attention spans among consumers, it seemed as if our brand was perpetually within the pattern of Slow Growth. With world-class product and brand equity, we were nevertheless incapable of figuring out the mystery of performance marketing. We went radical—we brought on a TikTok marketing agency.
In 90 days, sales grew 5X, three times greater engagement rate, and cost-per-acquisition reduced by more than anywhere else. Here’s our genuine, unapologetic account: issues that we encountered, how our TikTok ads agency resolved them, and what solutions led to performance—all the way down through TikTok Shop influencer marketing, Spark Ads, and conversion-driven creatives.

Our Scaling Experience with eCommerce using TikTok Marketing Agency

• We had become accustomed to thinking of TikTok as an entertainment platform of Gen Z. Viral dances and lip-syncs never quite made sense organically with our high-quality, mid-priced home essentials brand.
• Even with all of L’Oréal brandsmile-makers, of Youthforia and of faceless Amazon zealots, seemingly going viral at once on TikTok, we couldn’t help but question the question of whether TikTok can be an effective growth generator for us.
• We did not have TikTok presence. We did not have UGC. We did not have strategic influencer use. And we certainly were not using Spark Ads nor listing on TikTok Shop.

And what we did have were:

• A physical product with realizable, demonstrable use case
• Good word of mouth and good retainage
• A stagnant yet expanding Shopify DTC store

So I accompanied an ad agency on TikTok that handled representation of rising eCommerce start-ups. And that’s where things flipped.

The Beginning Point

Fast Steep Ad Costs and Growth Rate

• Before TikTok, all of our ad spending went through Instagram and Facebook. Although they had previously successfully generated ROI, recent ads were underperforming. Our cost-per-click had shot up 34% in 6 months, and return on ad spend was less than 1.5x. Google ads had reach but did not have scale. We were pouring capital down the drain attempting to compete within cannibalized feeds.
• Our organic strategy only very subtly attracted traffic. With daily regular calendar of Instagram and plenty of article-rich blogs each month, conversions were sluggish. We were thinking long-term with SEO—but we need results yesterday.

New TikTok Account

When we brought in the agency, we had:

• Sorry, no TikTok video
• Registration of no business
• No TikTok pixel installed
• Zero experience with managing creators and ads on the platform

We were arriving with no experience, and that was good. The agency never had bad habits it had to shed off—the sheet was pure white, and they were able to correctly set out the TikTok funnel on the very first day.

What the Agency Did

Our TikTok ad agency arrived with end-to-end strategy and execution play fine-tuned on TikTok’s commerce platform. Virality was not on the table whatsoever—their sole obsession being profitable conversions. All the diff it made.
That is what happened with 90-sprint.

1. Affiliate TikTok Shop Campaign through Affiliate Links

Top of those were benefiting from TikTok Shop influencer marketing.
Since it would be expensive using macro influencers with high commissions, the agency made use of micro and mid-tier influencers with high reach already affiliated on TikTok Shop’s affiliate campaign.

They controlled everything:

• Source and validate creators on TikTok Creator Marketplace and outside websites
• Negotiating affiliate commissions (10–25%)
• Scripting and creative briefing such that creatives noted key selling points
• Seeding of product and video timeline sync

These creators made organic-like of all of their contents with product links of TikTok Shop attached with in-app-click-to-purchase within TikTok app.
Up until the first 3 weeks, 15 creators had uploaded 37 videos. A home decor creator with 20K followers made 4 days of 2,500 sales with an excellent “TikTok made me buy it” hook and powerful CTA.

2. Pay-per-Click Spark Ads Scaling Out of Organic

After identifying high-performing creator content, TikTok ads agency introduced Spark Ads—the Spark Ad format of using creator videos as ads with original post integrity and reach.
The company launched Spark Ads with accuracy:

• Targeted custom audiences: Those users whose visit on TikTok Shop page did not result in any buy
• Lookalike Audiences: Reaching former buyers and high-potential web visitors
• Broad targeting: Home ordering, lifestyle, and green lifestyle interests

There was always a direct URL of our TikTok Shop listing on every Spark Ad with clear concise CTA like “Shop Now” or “Tap to Try This Hack.”
Responses were real-time. CTRs were 2.5 times greater than the earlier Facebook ads. CPMs were 40% lesser. Spark Ads provided creators with the best of all worlds: cred of creators + reach of ads.

3. Testing of Creative Hooks and CTA Optimization

A first-second TikTok hook is enough.
Our agency invested the first fourteen days of experimentation with more than 25 creative versions with descending/different openings:

• “this product did change my morning routine.”
• “You’ve had it all wrong since you were born.”
• “Believe all the reviews until you’ve tasted it…”
  
  

They tried creator and in-house UGC in the below formats:

• Before-and-after reveals
• Day-of-use integration
• Viral audio mashups
• Re-action-type voice

Each of the commercials were created in harsh TikTok-native format: 9–15 seconds at most, pay-off within a moment, native text onlays, product reveal within 3 seconds of watch, and harsh CTA.
Most effective CTA?
"Links in store—run before it’s sold!"
It broke.

4. Optimization of TikTok Shop Product Listing

Our ads and contents were made by the creative team, while the backend team made conversion-optimized product listing of our TikTok Shop. These were:

• Well-presenting product titles with keyword-searchable
• Phone-first product photography
• Bundle product options
• Countdown timers with time-limited offers
• Creating reviews and questions sections
• Marking with "Hot" and "Bestseller"

The company tried heatmaps as part of efforts at identifying higher-performing thumbnails and A/B tested on images, on prices, and on bundles.

Results at 90 Days

SpaceX 5X Revenue Multiples

• Our direct-to-client sales were $31K at month 1 and more than $158K at month 3.
• TikTok Shop alone generated 64% of all the freshly created order numbers of customers.
• Average order value increased 18% through the use of bundle offers and timely promotion.
• The affiliate producers made over $20K in commission collectively, promoting more and more productions.
• Good news? Our recently registered users were smaller, more active, and more likely donors on TikTok duets and commenting on behalf.
  
  

3X Higher Engagement across All Platforms

Even TikTok did not stay immune.
Since Spark Ads were employing creator handles, Our own profile grew exponentially. 90 days later:

• TikTok followers increased 0 to 23,000
• Instagram 41% higher reach (which is debatable because of cross-posting on TikTok)
• Signups were 2.4X greater as more registered after seeing us first on TikTok
• Our top 3 YouTube viral videos all exceeded 1M views and is still generating traffic.
  
  

Smaller CAC and Higher ROAS

• Reduced CAC from $27 to $9.60 with TikTok campaigns.
• Paid and organic blended combined ROAS was 6.2x.
• TikTok was 3 times cheaper than Facebook Ads.

Case Study: TikTok Agency Agreement of Youthforia

One of the original inspirations for work at the agency was Youthforia, the beauty company that 0–1M+ grew entirely on TikTok Shop influencer marketing.
Their TikTok advertising collaboration with an experienced TikTok advertising agency included:

• Strategical product seeding of 300+ micro
• UGC scaling with Spark Ads
• Seep integrations with TikTok Shop ads

Their recently viral color-shifting blush video racked up more than 4M views and attracted through thousands of brand-new customers—many through TikTok’s in-app buy pipeline.
And the bottom line is that you don’t need huge followers, only decent-enough content, decent-enough producers, and decent-enough agency execution.

Why An Ad Agency TikTok Partnership is A Game-Changer

If you're already considering TikTok as an experiment, you're already behind.
TikTok is the most token-ready physical product social platform at least as far as TikTok Shop as well as affiliate-commerce development is involved. But it’s not cocktail party.
That’s what our TikTok ads agency did that we would have never achieved by ourselves:

• Collaborations with creators generating real content at scale
• Extensive test suites for discovering high-performing hooks
• Pixel-wise data comparison and segmentation of audiences
• Up-to-date monitoring of TikTok populars and popular music
• Snappily integrated TikTok Shop support, từ đăng listing product đến fine-tune

We re-envisioned the entire marketing funnel in 90 days—the agency sustained momentum.

If you're either e-commerce business or direct-to-consumer brand and have not yet cracked TikTok with industry experts, it is high time.
