Background
An established player in the automotive sector struggled to gain traction on Amazon in a fiercely competitive category. Despite quality products and the exclusive rights to trade in Australia, they needed a way to quickly scale revenue and stand out against seasoned rivals.
Challenges
Urgent need to accelerate revenue and expand market share
Low brand visibility and poor positioning against top competitors
Difficulty in identifying high-converting customer search behaviours
Limited efficiency in ad spend and overall account structure
The Unmaze Solution
Comprehensive Keyword Research: Deep-dived into the automotive category and product catalog to uncover and map over 150 high-intent, product-relevant keywords. This ensured campaigns aligned with live customer search behaviour, maximising ad relevancy and improving performance from the outset.
Bidding Strategy Optimisation (Dynamic Bids - Down Only): Developed a custom bidding strategy that dynamically lowers bids in real-time for low-converting traffic, maximising ROAS and minimising wasted spend. This approach was key for new accounts and budget-conscious campaigns, ensuring efficiency without compromising on competitiveness.
Full-Funnel Advertising Architecture: Constructed a unified funnel across campaign types:
Auto Campaigns: Deployed for discovery and keyword harvesting, driving new keyword insights from real shopper queries.
Manual Campaigns: Focused on proven, high-conversion keywords for tight budget control.
Sponsored Brand Campaigns: Increased mid-funnel awareness by targeting relevant branded search terms, driving traffic to detailed brand store pages.
Sponsored Display: Built upper-funnel presence with remarketing, targeting users who already viewed or purchased within the category.
Competitor Targeting: Ran offensive campaigns to capture market share from rival brands and defensive campaigns for brand protection.
Scalable Account Structure: Designed separate campaigns by intent, product line, and targeting type. This modular structure allowed clear allocation of spend, efficient scaling, and real-time adjustments as performance data accrued.
Low Total Advertising Cost of Sale (TACoS): Managed and benchmarked across all campaigns, ensuring advertising directly drove incremental gross sales and supported ongoing account health and scalability.
