CaliberBot is a bot in the SEO crawlers category, operated by Conductor.
Caliperbot crawls Conductor clients' and prospects' websites for HTML feature extraction to power Content Analytics features within our Searchlight web application.
SEO crawlers map links, keywords and technical issues for SEO tools and backlink databases. They help the tool's customers, often your competitors, rather than you. Rate limit or block the ones you do not use.
CaliberBot identifies itself with this user agent string:
Caliperbot/1.0 (+http://www.conductor.com/caliperbot)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.
We have not confirmed whether CaliberBot 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.

User-agent: Caliperbot Disallow: /private/ Disallow: /search

CaliberBot works for an SEO tool's customers, often your competitors. It adds server load without readers, so rate limit or block it unless you use the tool.
Transfon Security for publishersSEO crawlers map landing pages and links for competitor research. Keep CaliberBot's visits out of campaign data.
Transfon Security for advertisersCaliberBot can map your catalogue, prices and site structure for competitors. Block it unless you use the tool yourself.
Transfon Security for e-commerceAllow CaliberBot only if your team uses the tool; otherwise rate limit it on docs and marketing pages.
Transfon Security for SaaS and APIsrobots.txt is a request, not an enforcement. Transfon Security shows CaliberBot by name in the Top Bots report, so you can see how often it visits and which pages it reads. Block or allow it with a User Agent rule, or slow it down with a rate limit decision rule.

CaliberBot is a bot in the SEO crawlers category, operated by Conductor. Caliperbot crawls Conductor clients' and prospects' websites for HTML feature extraction to power Content Analytics features within our Searchlight web application.
We have not confirmed whether CaliberBot 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.
Add "User-agent: Caliperbot" followed by "Disallow: /" to the robots.txt file at the root of your site. To enforce it, block requests whose user agent contains "Caliperbot/" at your WAF. In Transfon Security that is one User Agent block rule.
No. robots.txt is voluntary, so CaliberBot may not follow it, and anyone can send CaliberBot's user agent, so a fake CaliberBot ignores your rule. Enforce the rule where requests arrive, at your WAF, and check the source network.
