ByteDanceTraining crawler

Bytespider

Bytespider is a ByteDance crawler associated with training and powering AI products. This record has no current ByteDance source, so treat a matching request as unverified.

Training only. It does not decide whether you appear in answers.

Should you block Bytespider?

You can, but it may not listen. ByteDance has not documented Bytespider, so treat any rule as a request. Blocking it is a training-data policy choice, but ByteDance compliance has been reported as inconsistent by crawler trackers.

About robots.txtCrawler registries and Trakkr’s seed registry flag inconsistent robots.txt compliance.

robots.txt
User-agent: Bytespider
Disallow: /

Asks Bytespider not to crawl any page. Add it to the robots.txt file at the root of your site, above any wider rules.

Ignored robots.txt?

Bytespider collects pages for model training. Training inclusion is not the same as being cited, so measure where AI answers actually cite your site before drawing conclusions from crawl logs.

Spot it in your logs.

Match the name, then check where the request came from. Anyone can copy a user-agent. Search your own logs for Bytespider.

  1. 1

    Match the name

    Search your server or CDN log for Bytespider, case-insensitive. A match is a clue, not proof.

  2. 2

    Check the source

    ByteDance publishes no IP ranges, reverse DNS or signatures for Bytespider in the sources here, so it cannot be verified. Treat matches as unconfirmed.

Serve the content in HTML

The cited operator material does not verify JavaScript rendering. Serve useful HTML before client-side JavaScript where possible.

How this is measured

Finalized daily crawler summaries from sites connected to Trakkr, grouped by the crawler named in each request. Trakkr’s own site is excluded. A site counts as reached in a week when it logged at least one request from Bytespider. The typical figure is the median weekly requests among the sites it reached.

  • This is a sample of connected sites, not the whole web.
  • A matching user-agent does not prove the named operator sent the request.
  • Requests are not unique pages, training use or citations.
  • Crawlers seen on fewer than 10 sites are not shown. Classic search crawlers such as Googlebot are not collected on every site, so they are left out.
