Challenge
An ecommerce brand was struggling to scale Meta Ads profitably. Rising CPMs and ad fatigue were driving down return on ad spend, while audience targeting had become too broad. The objective was to stabilise performance and improve revenue efficiency without increasing monthly ad spend.
Solution
We refreshed creative with product-led static and video assets, restructured campaigns around clear funnel stages, and tightened audience segmentation. Retargeting was rebuilt to prioritise high-intent users, supported by ongoing creative testing and performance optimisation.
Result
Return on ad spend increased by 58%, while revenue from Meta Ads grew by 41% over the campaign period. CPA reduced consistently as creative performance improved, delivering sustainable growth without increasing media spend.
Since our inception in 2018, we've empowered businesses to find their voice, make decisive choices, and seize opportunities in an ever-evolving industry.

Challenge
The client had only gotten cars from offline methods and were not satisfied with their current # of new cars per month. Their offline methods included referrals from other automotive businesses and local car events to attract customers. This offline effort resulted in a high cost per customer, due to labor efforts for each method, and time to convert new customers. They knew they needed online to scale, but knew little about advertising.
Solution
We identified the gaps in the customers online buying experience. The website had poor CRO and SEO, holding it back from free organic customers. It lacked key selling information to prime the customer to purchase. What makes the shop different, why should the customer do a wrap? We analyzed why customers bought, and updated their website to match intent. We then launched a full scale campaign on Google Ads and Meta Ads (facebook/instagram). Optimized keywords, ad copy, and retargeting.
Result
We added 638 cars over 12 months. Cost per customer was only $235 for a $4k average wrap shop. First couples months took time to collect data, but on average over 12 months delivered 50 new cars per month. Resulting in $2.52M revenue to the business.
We are the digital growth experts. As an award-winning provider of digital marketing and websites to leading brands, we’ve worked for more than a decade with one key goal in mind - to get businesses more customers online.

A UAE-based B2B fresh produce supplier was running Google Ads with monthly spend of AED 8K–9K but struggled to scale profitably. ROAS was stuck below 3x, revenue remained underwhelming, and lack of proper eCommerce tracking limited optimization. Campaign structure lacked product-level clarity, making it difficult to identify high-performing SKUs and improve conversion efficiency.
Solution
We implemented a hybrid strategy combining Smart Shopping and Search campaigns to capture both demand and intent. Advanced eCommerce tracking with purchase-level attribution was deployed for accurate data. Campaigns were restructured with SKU-level segmentation, supported by ROAS-based bidding and custom B2B remarketing audiences to re-engage high-value buyers and improve conversion quality.
Result
Revenue scaled from $48K to $105K within 60 days, delivering more than 2x growth. ROAS improved from 2.89x to 4.83x, significantly increasing campaign profitability. Purchase conversions grew by 81%, driven by better targeting, structured campaigns, and accurate tracking. The result was a scalable and highly efficient B2B eCommerce growth engine.

Challenge
A premium beauty brand faced the challenge of launching a new fragrance line in a competitive e-commerce market. They needed to ensure a strong market entry, maximize online sales, and maintain a low CPA to achieve a high ROAS. The brand sought our expertise to manage a pilot campaign, with the goal of testing the e-commerce waters while ensuring cost efficiency and a successful product launch within the first 90 days.
Solution
We implemented a comprehensive multi-channel marketing strategy, including targeted keyword search campaigns, advanced retargeting, and geofencing around luxury retail locations. To optimize cost efficiency, we meticulously managed CPA through real-time bid adjustments and strategic budget allocation. Data-driven approaches like A/B testing and real-time analytics allowed us to refine our strategy, ensuring that we captured significant market share and drove substantial e-commerce conversions.
Result
The campaign generated 30.4M impressions and achieved 9,973 online sales within 90 days, driving over $523,575 in e-commerce revenue. We secured an exceptionally low CPA of $3.40, far below industry averages, and delivered a 4.1x ROAS. The success of the pilot led to our agency being entrusted with the full display and programmatic advertising budget, further optimizing the campaign and setting a new benchmark for e-commerce launches.
