Olifant Digital
5
(12 reviews)
Profitable Amazon and DTC growth, run by senior specialists daily.
Olifant Digital is a full-service Amazon agency and Amazon PPC agency managing $100M+ in annual Amazon client revenue across 50+ accounts. Founded in 2018, the agency works with established brands across the US, UK, and EU, providing Amazon PPC management, SEO, listing optimization, A+ content, catalog operations, and product launches as one integrated system. All accounts are managed exclusively by senior Amazon specialists with 7+ years of experience, with no junior account managers involved. This senior-only model is a key differentiator in the Amazon agency space. Olifant Digital uses a TACoS-first PPC methodology focused on total Amazon profitability rather than ad-attributed ROAS alone. Its 1-1-1-1 campaign structure (one campaign per ASIN, match type, ad type, and targeting group) enables precise SKU-level control and removes data blending. PPC is fully integrated with conversion and operational optimization. Listing SEO, A/B-tested creative, A+ content, profitability tracking, inventory oversight, and account health monitoring all run alongside campaign management to ensure scalable performance. The agency also operates Olifant AI, a proprietary Amazon PPC and account management platform that tracks keyword rankings, indexation, listing quality signals, and SEO performance daily, enabling fast optimization before issues impact revenue. Olifant Digital has 30+ published case studies with verified results, including: • Ekster — $688,406 added annual profitability • WedgeGuys — +$305,771 monthly revenue, 17% lower ACoS • Elite Jumps — +124% monthly revenue in 3 months • MatchaBar — +$114,305 monthly revenue increase • Balanced Tiger — +171% monthly revenue, 50% lower ACoS Every engagement includes a 60-day money-back guarantee if results do not improve. Combined with a 98% client retention rate, Olifant Digital is built for established Amazon brands seeking hands-on PPC scaling with strong margin control.

UAATEAM Corp.

eCommerce growth partner. We stabilise ROAS first, then scale – Google Premier & Meta Partner
Highly recommended
Top awarded
Google Premier Partner and Meta Partner since 2017, rated 4.99/5 by 38 clients. UAATEAM is a profit-driven growth partner helping eCommerce brands scale predictably – stable ROAS, protected margins, no wasted budget. Rather than simply driving traffic, we build structured performance models designed to handle scale. Many eCommerce brands can launch ads – the real challenge is maintaining consistent ROAS, protecting margins, and scaling without volatility. We work with businesses that are already investing in paid media but lack predictability in their results. Our approach is simple: stabilize first, then scale. Before increasing budgets, we ensure that ROAS is consistent over time, acquisition aligns with real margins, analytics and attribution are properly structured, and retention supports paid traffic. Scaling should be a calculated decision, not a reaction to short-term spikes. Our expertise includes Google Ads, Meta Ads, email marketing and lifecycle automation, SEO for sustainable acquisition, and full-funnel analytics. We expand channels step by step, validating performance before accelerating investment. We partner with founders who value long-term strategy, disciplined execution, and profitable growth. If you’re looking for predictable performance and structured scaling – we’re ready to collaborate.
