About AudD

On-demand music recognition API operated by AudD

Bots that do not fit the other categories. Review their purpose and allow only what you need.

AudD user agent

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 AudD in robots.txt

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

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

Who should care about AudD

Publishers

Allow AudD if it is a service you use, and keep its visits out of page views and ad requests either way.

Media buyers and advertisers

AudD is not a person. Exclude it from campaign and conversion data so reports reflect real visitors.

Transfon Security for advertisers

E-commerce

Allow AudD only if it works for your store, and keep it away from cart and checkout.

If AudD is a service you use, allow it on the endpoints it needs and block it elsewhere.

Frequently asked questions

What is AudD?

AudD is a bot in the other bots category, operated by AudD, LLC. On-demand music recognition API operated by AudD

Does AudD respect robots.txt?

We have not confirmed whether AudD 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 AudD?

Add "User-agent: AudD" followed by "Disallow: /" to the robots.txt file at the root of your site. To enforce it, block requests whose user agent contains "AudD" at your WAF. In Transfon Security that is one User Agent block rule.

Is robots.txt enough to block AudD?

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

Should I block AudD?
