A marketing agency managing dozens of competitor analysis projects simultaneously
WebPromo is a digital marketing agency specializing in competitive market analysis and SEO strategy for e-commerce and B2B clients. With a growing portfolio of projects, the team needed real-time competitor data to build insights and reports for their clients. As data demands scaled, third-party analytics platforms became both costly and limiting, creating bottlenecks in their workflow.
Challenge
Trapped by expensive subscriptions and closed platforms
WebPromo's growth hit a wall with third-party analytics platforms. While these services provided valuable competitor data, they came with serious constraints that made scaling impossible.
Core problems
High subscription costs: Multiple analytics tools eating into margins, with pricing increasing as data needs grew
Limited data access: Platforms restricted the depth and breadth of available data, forcing compromises on analysis quality
No API integration: The most valuable data source lacked API access, making it impossible to connect with internal CRM and reporting systems
Manual data export: Analysts spent hours copying data between platforms to create client reports
No scalability: Adding more clients or competitors meant proportionally higher costs with no efficiency gains
The goal
Build an independent data collection system that could gather competitor intelligence automatically, integrate with existing tools, and scale without proportional cost increases.
Custom Parser & Data Pipeline
The core solution
We engineered a sophisticated parser that navigates a leading SEO analytics platform (which lacks public API) to extract competitor data systematically and reliably.
Automated data collection:
- Retrieves SEO metrics for specified competitor domains
- Gathers keyword rankings, backlink profiles, and traffic estimates
- Collects data without overloading source systems (respectful scraping practices)
- Runs on scheduled intervals to keep data fresh
Smart data structuring:
- Custom database schema optimized for competitive analysis
- Normalized data from multiple sources into unified format
- Data validation and quality checks
- Historical tracking for trend analysis
Scalable architecture:
- Modular design allows easy expansion to new data sources
- Intelligent scraping that mimics human behavior
- Rate limiting and retry logic for reliability
Database & Infrastructure
- Supabase with optimized indexing for fast queries
- Automated backup and recovery systems
- Scheduled updates keep data current
- Error monitoring and automated alerts
Integration capabilities
- Export pipelines for Metabase
- Real-time data sync
- Flexible query system for ad-hoc analysis
Technical breakthrough
- System collects data without impacting source platform performance
- Automatic scheduling with intelligent retry mechanisms
- Modular codebase — easy to scale for other data sources
- Complete independence from third-party APIs
