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.
