About SilktideBot

Website accessibility, SEO, and content quality scanner

Accessibility checkers scan pages for WCAG issues on behalf of site owners and auditors. Allow the checkers you run and keep them out of analytics.

SilktideBot user agent

SilktideBot identifies itself with this user agent string:

  • Mozilla/5.0 (compatible; SilktideBot/1.1; +https://help.silktide.com/en/articles/4606146-silktidebot-our-site-scanning-bot)

Anyone can copy a user agent string. Transfon Security also checks where each request comes from, so a request that claims to be a known crawler but comes from the wrong network is treated as a fake, not as the real crawler.

How to block SilktideBot in robots.txt

We have not confirmed whether SilktideBot follows robots.txt. Add a rule, then check your logs to see that it stopped. robots.txt is a plain text file at the root of your domain, such as https://example.com/robots.txt.

Things to know

  • Each host needs its own file. Rules on www.example.com do not apply to shop.example.com.
  • A crawler obeys only the most specific group that names it. Once you add a User-agent: Silktide group, SilktideBot ignores your User-agent: * rules, so repeat any that should still apply.
  • The user agent name is not case sensitive. We take Silktide from SilktideBot's user agent; check Silktide's own documentation if it publishes a different robots.txt name.
  • Crawlers cache robots.txt, so changes can take up to a day to apply. Disallow stops crawling but does not remove pages already collected or indexed.

Limits of robots.txt

  1. SilktideBot may not follow the rule. robots.txt is a request that nothing enforces, and we have not confirmed that SilktideBot follows it. Check your logs after adding a rule.
  2. The user agent could be fake. robots.txt matches the name a request claims. Anyone can send SilktideBot's user agent, and a scraper using it is not bound by Silktide's robots.txt policy. Only checking the source network tells a real SilktideBot from a fake one.

Treat robots.txt as a statement of your policy, and enforce it where requests arrive.

Does SilktideBot respect robots.txt?

We have not confirmed whether SilktideBot follows robots.txt. Add a robots.txt rule, then check your logs to see that it stopped, and block it by user agent if it did not.

How do I block SilktideBot?

Is robots.txt enough to block SilktideBot?

No. robots.txt is voluntary, so SilktideBot may not follow it, and anyone can send SilktideBot's user agent, so a fake SilktideBot ignores your rule. Enforce the rule where requests arrive, at your WAF, and check the source network.
