Project 1: Fast Fashion New York, NY

Scaling Dynamic Product Ads

The Challenge

The brand was running static image ads for a massive 2,000+ SKU catalog. Ad fatigue was high, and Customer Acquisition Cost (CAC) was creeping over $65.

The Strategy

Integrated their Shopify feed with Meta for Advantage+ Shopping Campaigns (DPA). Used broad audience targeting to let the algorithm match specific SKUs to highly intent-driven buyers.

★★★★★
Verified Client Feedback

"Advantage+ and DPA completely automated our ad creation. We went from manually updating out-of-stock ads to a system that scales our bestsellers automatically."

Monthly Orders +415%
ROAS 580%
Project 2: Clean Skincare Miami, FL

Exploding on TikTok Shop

The Challenge

The brand had viral moments on TikTok organically, but users were dropping off when forced to leave the app to check out on their website.

The Strategy

We fully integrated TikTok Shop to allow seamless in-app checkout. We then deployed Spark Ads using existing top-performing creator content to push traffic directly to the Shop tab.

★★★★★
Verified Client Feedback

"Removing the friction of a website checkout was the missing puzzle piece. Our conversion rates from social media literally quadrupled overnight."

Before: Conversion Rate 1.2%
After: TikTok Shop CVR 5.8%
Monthly Revenue $185k
Creator ROI 9.2x
Project 3: Home Decor Austin, TX

Mastering Google Performance Max

The Challenge

Standard Google Shopping campaigns were cannibalizing brand search. The client had high-quality lifestyle imagery but no way to properly utilize it within standard shopping feeds.

The Strategy

Upgraded to Google Performance Max (PMax). Created robust "Asset Groups" pairing their lifestyle images and video tours directly with specific product catalogs, targeting "Home Renovation" audiences.

★★★★★
Verified Client Feedback

"Seeing our products pop up on YouTube, Display, and Search all from one campaign was incredible. The visual asset groups drove our best quarter ever."

Project 4: Electronics Seattle, WA

Recovering 75% Cart Abandonment

The Challenge

Driving traffic wasn't the issue. The store was experiencing a massive 75% cart abandonment rate on high-ticket consumer electronics.

The Strategy

Built an aggressive, multi-channel retention strategy. Implemented a 3-step Klaviyo email sequence paired with an SMS text reminder offering a time-sensitive 10% discount on abandoned carts.

★★★★★
Verified Client Feedback

"The SMS integration was a goldmine. People were ignoring the emails but immediately clicking the text link to finish their purchase."

Campaign Performance

Before: Cart Recovery Rate 4.5%
After: Cart Recovery Rate 22.8%
SMS ROI 32x
Recovered Rev/mo +$65k
Project 5: Custom Jewelry Dallas, TX

Visual Discovery via Pinterest Ads

The Challenge

Search intent was too highly contested. CPCs on Google for "custom engagement rings" were pushing $15-$20, wiping out margins.

The Strategy

Moved to an upper-funnel visual discovery strategy using Pinterest Shopping Ads. Targeted users actively building "Wedding Board" pins with highly aesthetic catalog uploads.

★★★★★
Verified Client Feedback

"Pinterest brought us a completely different type of buyer—one who was early in their planning stage but highly motivated. The ROI is fantastic."

Campaign Performance

Before: Search CPC $18.50
After: Pinterest CPC $0.85
Catalog Reach 1.8M
Attributed Sales +210%
Project 6: Subscription Box Denver, CO

Skyrocketing Customer LTV

The Challenge

Customer Acquisition Cost was acceptable, but churn was massive after the first box. LTV (Lifetime Value) wasn't supporting the ad spend.

The Strategy

Built a 6-week post-purchase email and SMS retention funnel. Offered tiered rewards and easy "skip a month" options rather than outright cancellations to retain users.

★★★★★
Verified Client Feedback

"Fixing our leaky bucket changed the entire math of our business. Our subscribers are staying on an average of 4 months longer now."

Campaign Performance

Before: Churn Rate 42%
After: Churn Rate 14%

MRR Growth +220%
Project 7: Fitness Equip. Los Angeles, CA

YouTube Video Action Campaigns

The Challenge

It was impossible to demonstrate the quality and unique mechanics of their home-gym equipment using static imagery. Conversion rates were stalling.

The Strategy

Launched YouTube Video Action Campaigns targeting users actively searching for "home workout routines". Added product feeds directly beneath the video ad to allow instant checkout.

★★★★★
Verified Client Feedback

"Allowing users to click and buy right from a YouTube video showcasing the product in action bypassed our entire educational hurdle."

Project 8: Pet Supplies Chicago, IL

VIP Loyalty & Replenishment

The Challenge

High volume of one-off purchases for dog treats and supplements. Without repeat buyers, scaling ad spend on Meta was becoming unprofitable.

The Strategy

Integrated Smile.io for a points-based VIP program. Set up predictive Klaviyo replenishment flows triggered exactly 30 days after a consumable purchase to drive automatic re-orders.

★★★★★
Verified Client Feedback

"Our repeat customer rate exploded. The automated emails basically act as a silent sales team generating recurring revenue."

LT

Laura T.

Owner, Pet Store

Campaign Performance

Before: Repeat Rate 12%
After: Repeat Rate 45%
LTV +$65
Email Rev Share 32%
Project 9: Supplements Atlanta, GA

Amazon PPC Domination

The Challenge

Lost in the noise of Amazon's massive supplement market. Their organic listings were buried, and automatic PPC campaigns were wasting spend on irrelevant search terms.

The Strategy

Built a full Amazon Brand Store. Transitioned from Auto to Manual exact match campaigns, utilizing Sponsored Brands Video to stand out in the search feed.

★★★★★
Verified Client Feedback

"The video ads on Amazon completely separated us from the generic white-label brands. Our Best Seller Rank skyrocketed."

Project 10: Luxury Watches San Francisco, CA

Omnichannel Sequential Retargeting

The Challenge

Selling a $4,000 product online means a very long consideration phase (14-30 days). Single-touch ad campaigns were failing to close the deal.

The Strategy

Created a 30-day sequential retargeting loop. Day 1-7: Lifestyle video on Meta. Day 8-14: Trust-building unboxing on YouTube. Day 15-30: Direct offer/financing ad on Google Display.

★★★★★
Verified Client Feedback

"Following our customers across the web with a targeted story rather than spamming the same image closed a massive gap in our sales funnel."

Campaign Performance

Before: Conversion Rate 0.4%
After: 30-Day CVR 2.1%
