In today’s data-driven business world, web scraping offers an appealing opportunity to quickly and efficiently obtain valuable information. However, the gap between technical feasibility and legal permissibility is often complex and nuanced. This article examines the critical aspects of web scraping from legal and practical perspectives, focusing on the German market.
Web scraping operates within a differentiated legal framework in Germany. Its permissibility depends on various factors, including both the "how" and "what" of scraping. Key considerations include not only data protection laws but also competition and copyright regulations. A critical factor is whether the data is publicly accessible or protected content. A comprehensive legal assessment can help avoid problematic gray areas. Read more here.
Web scraping's legal status varies based on the type of data being collected. Publicly accessible factual data is generally legal to scrape as it isn't protected by copyright. However, scraping personal data often raises legal concerns due to GDPR compliance requirements, which mandate explicit consent or another legal basis for data processing. Scraping protected content constitutes copyright infringement and is illegal. For competition-relevant data, legality depends on specific terms of use and competition law, requiring case-by-case evaluation.
GDPR compliance remains a major challenge for many users since personal data processing requires either explicit consent or an alternative legal foundation. Learn more about GDPR compliance here.
Scraping Google services requires special attention. While Google Search is generally publicly accessible, its terms of use prohibit automated scraping. This is particularly relevant when considering whether scraping services like Google Maps or the search engine is worth pursuing, as alternatives like APIs are often legally safer and better documented.

In e-commerce, particularly on platforms like eBay, web scraping is a double-edged sword. While price comparisons are generally legal, aggressive scraping practices may violate terms of use and competition law. Companies engaging in these practices should always comply with platform guidelines to avoid legal consequences.
