Web Crawler for Compliance Auditing
Project Summary
This is a custom-built web crawling and auditing tool designed to identify websites from Germany that directly load Google Fonts from external servers instead of hosting them locally — a practice that may violate regional GDPR and privacy compliance regulations. The system systematically crawls and audits websites, extracting this specific data and compiles the findings into a structured CSV report for review and enforcement.
Challenges
The client needed an automated, reliable, and scalable solution to:
Our Solution
Leveraging our expertise in web scraping, automation frameworks, and asynchronous task management, we designed a robust, high-performance solution tailored to this compliance use case.
Technology Stack
- Backend: Python, Django
- Web Crawling & Parsing: Selenium, BeautifulSoup, Requests
- Task Management: Django Celery, Redis
- Data Export: CSV writer utilities
Business Impact
● Enabled fast and reliable audits of websites within Germany for external Google Font dependencies
● Reduced manual auditing effort by over 90% through automation
● Ensured alignment with GDPR compliance guidelines, helping clients identify and
rectify privacy risks
● Delivered an easily consumable CSV report for regulatory and legal teams
Key Functional Features Developed:
-
Automated Web Crawler:Custom-built using Selenium, BeautifulSoup, and Requests libraries to scan website source codes and detect external Google Font calls.
-
Task Scheduling & Management:Integrated Django Celery and Redis for efficient, asynchronous background task handling and distributed crawling operations.
-
GDPR-Compliant Crawling Strategy:Implemented crawl delay, user-agent rotation, and IP management techniques to maintain ethical scraping standards and avoid detection.
-
Dynamic Data Parsing & Filtering:Extracted specific font loading URLs and verified external dependencies against the criteria.
-
CSV Report Generation:Automated compilation of identified websites and their Google Font usage status into a structured CSV file for easy reporting.
Deliverables
