Objective
The main goal was to scale sales through Google Ads with a focus on profitability and advertising system manageability.
We faced the following objectives:
- consistent growth in order volume
- maintaining a high ROAS in a competitive technical niche
- effective management of a large and diverse product range
- building a PPC system that works for both B2C and B2B clients
What We Did
Challenges
The security systems niche presents a number of specific challenges:
- a large product feed with hundreds of SKUs
- varying margins and conversion rates across categories
- a mix of impulse and expert-driven demand
- a longer decision-making cycle for certain products
- risk of budget waste with improper scaling
The key challenge was to scale without losing profitability.
Strategy
A combined PPC strategy was implemented, with Performance Max as the primary scaling tool.
Key strategic decisions:
- Performance Max as the main sales driver
- segmentation of PMax campaigns by product categories (surveillance, alarms, power supplies, accessories, etc.)
- separation of branded and non-branded search
- campaign optimization based on conversion value rather than volume
- budget reallocation between categories based on performance
Execution
During the process, we:
- built a structured system of Performance Max campaigns
- optimized shopping and search campaigns for different demand types
- tested various scaling scenarios
- disabled underperforming combinations and campaigns
- concentrated budget on the highest-performing categories
All decisions were driven by analytics and actual data.
Results
Key performance metrics:
- achieved a stable ROAS of approximately 17–18
- Performance Max became the primary source of conversions
- search campaigns effectively captured high-intent demand
- scaling was achieved without loss of efficiency
Analytics and confirmation of results
