Blocking CCBot Impacts Training Data
daluoseo · x · 2026-07-12
Many websites block CCBot, the Common Crawl spider, in their robots.txt files.
The post explains Common Crawl's role: it continuously scrapes and archives massive amounts of web data, which is commonly used as foundational training data for various large language models. If you block CCBot, your website will likely be excluded from the Common Crawl index, making it much less likely to be included in LLM training data.
The core takeaway is that your robots.txt crawler policy directly impacts whether your site will appear in future AI training corpora.
