Overcome website limitations – Many websites restrict access to data downloads, caches and APIs. Web scraping technology lets you bypass these limits to extract required information.
Lower costs of data acquisition – Manually compiling data costs enormous human effort and expenses. Automated scraping reduces data collection costs by 80% to 90%, as per Web Data Integration.
Drive strategic decisions – With web scraping, you can realize data-driven management based on market realities rather than intuitions. A study by MarketingSherpa found that data-driven organizations are 64% more likely to meet business goals.
In essence, web scraping should be a foundational Big Data technique for every modern, insights-driven organization.
Best Practices for Effective Web Scraping
Here are some tips and strategies to ensure your web scraping efforts are productive, ethical and keep you on the right side of the law:
Review robots.txt – The robots.txt file contains rules for web crawlers set by a website owner. Program your web scrapers to parse robots.txt and avoidbanned pages or scraping patterns.
Scrape judiciously – Aggressive scraping can overload target sites and disrupt services. Use throttling to limit crawl rates to a few requests per second.
Rotate proxies – Proxies hide the real IP addresses and locations of your web scrapers. Using proxy rotation makes your scraping appear non-suspicious.
Customize user-agents – Configuring scrapers with a customized browser user-agent string helps avoid detection as an unknown bot. But don‘t impersonate a real user.
Seek explicit consent – For large-scale scraping, it‘s wise to obtain a website‘s permission in advance to avoid legal concerns. Make sure you communicate the intended data use.
Respect opt-out signals – Many websites now use standards like humans.txt to indicate preferences over scraping. Honor any opt-out requests you come across.
Scrape ethically – Never scrape confidential user data, pricing from non-public sources, or data you do not plan to use. Build ethics into your web scraping governance.
Use legal scrapers – Choose web scraping software and services carefully to ensure they employ scraping techniques compliant with standards like GDPR and CCPA.
Consult experts – Partnering with experienced web scraping professionals will help you implement scraping best practices tailored to your needs while limiting compliance risk.
Following such prudent web scraping guidelines reduces the chances of failure due to getting blocked or banned while also keeping your brand safe and ethical.
Unlocking Business Value from Data Mining
