About ConvermaxBot

Convermax Site Search Indexer

Feed fetchers poll RSS and Atom feeds for readers, aggregators and podcast apps. They usually request feeds only, so they are cheap to allow. Watch for fetchers that pull full pages at high rates.

ConvermaxBot user agent

ConvermaxBot identifies itself with this user agent string:

  • Convermax/1.0 (+https://docs.convermax.com/indexer)

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 ConvermaxBot in robots.txt

We have not confirmed whether ConvermaxBot 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.

Block ConvermaxBot from the whole site

User-agent: Convermax
Disallow: /

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: Convermax group, ConvermaxBot ignores your User-agent: * rules, so repeat any that should still apply.
  • The user agent name is not case sensitive. We take Convermax from ConvermaxBot's user agent; check Convermax Corp.'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. ConvermaxBot may not follow the rule. robots.txt is a request that nothing enforces, and we have not confirmed that ConvermaxBot 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 ConvermaxBot's user agent, and a scraper using it is not bound by Convermax Corp.'s robots.txt policy. Only checking the source network tells a real ConvermaxBot from a fake one.

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