What is Bytespider?

Bytespider is an AI crawler. Bytespider is ByteDance's web crawler used to gather training data for their AI large language models. It's primarily used to scrape web content to train TikTok's AI features and other ByteDance AI products.

Bytespider matters for AI visibility because the pages it collects can shape what large language models learn about your brand, products, and expertise. Allowing it can strengthen how accurately AI systems describe and recommend you, while disallowing it keeps your content out of training data. Either way, knowing Bytespider visits is the first step to managing how your brand shows up in AI search.

Tracking which AI crawlers and agents reach your site, and what they do once there, is the foundation of generative engine optimization. See our guides to AI crawlers and robots.txt to control automated access and protect your AI search visibility.

How to handle Bytespider

If you do not want Bytespider using your content for AI training, disallow it in robots.txt. If you are comfortable contributing to AI systems, leave it allowed.

To control Bytespider, add a rule for its user agent to your robots.txt:

User-agent: Bytespider
Disallow: /

Bytespider generally honors robots.txt directives.

Examples

  • A publisher reviews server logs, sees Bytespider requesting long-form articles, and decides whether to allow or disallow it in robots.txt.
  • A site owner adds a Disallow rule for Bytespider to keep premium guides out of AI training datasets.
