For online comparison engines, continuous access to accurate product and pricing data is mission-critical. Scraper failures can disrupt feeds, cause incorrect listings, and reduce customer trust.
This case study shows how a comparison engine partnered with Grepsr to:
- Maintain 99.9% data uptime
- Eliminate scraper failures and interruptions
- Ensure reliable, structured, real-time product and pricing data
- Reduce engineering overhead while improving operational stability
By treating web data as a managed, resilient service, the comparison engine ensured uninterrupted feeds, accurate pricing, and improved customer experience.
The Challenge: Unreliable Scraping Impacted Business
The comparison engine faced several critical challenges:
- Frequent scraper failures due to website changes and anti-bot measures
- Delayed or missing data affected pricing accuracy and product listings
- Engineers spent significant time fixing and maintaining scrapers
- Data interruptions impacted customer experience and trust
“Even a few hours of downtime could lead to inaccurate pricing and frustrated users,” said the CTO.
“We needed a reliable way to ensure consistent data availability,” added the Head of Operations.
The company required a robust, automated solution capable of maintaining continuous data feeds across multiple sources.
Why Traditional Approaches Were Insufficient
Internal scripts and basic scraping tools presented multiple drawbacks:
- High maintenance overhead for constantly breaking scrapers
- Limited ability to handle website layout changes automatically
- Inconsistent data delivery and frequent downtime
- Engineers diverted from higher-value projects to firefight scraper issues
“We realized that relying on in-house scraping would continue to be unstable and costly,” said the VP of Engineering.
