Common Crawl: Non-Profit Web Crawling Data
Common Crawl is a non-profit organization that crawls the web and makes web crawl data available to the public for free, supporting research, development, and entrepreneurship.
What is Common Crawl?
Common Crawl is a non-profit organization with the goal of building and maintaining an open repository of web crawl data that is accessible and useful to the public.
They crawl the web on a regular basis and process the crawled data to extract structured information and metadata. This data is then made available for download at no cost through Amazon Web Services public datasets.
The structured crawl data from Common Crawl can be used by a variety of stakeholders including researchers, developers, data scientists, and entrepreneurs. For example, the data can be analyzed to gain insights into web page content, conduct search engine research, train machine learning models, build browser extensions, develop web accessibility tools, and more.
Some key benefits of using Common Crawl data include the sheer scale of the repository (petabytes of data), regular fresh crawls, simplified access through AWS, extracted metadata, and a very permissive license allowing free use. Overall, Common Crawl enables innovation by lowering barriers to access web crawl data.
