About GoogleScholar

Google Scholar uses a bot to crawl and index scholarly literature from academic publishers, repositories, and university websites. This populates its academic search engine.

Search engine crawlers index your pages so they can appear in search results. Keep the genuine ones allowed and verify them, because fake search crawlers are one of the most common disguises for scrapers.

GoogleScholar user agent

GoogleScholar identifies itself with this user agent string:

  • Googlebot-IA/2.1

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 GoogleScholar in robots.txt

We have not confirmed whether GoogleScholar 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 GoogleScholar from the whole site

User-agent: Googlebot-IA
Disallow: /

Block GoogleScholar from some folders

User-agent: Googlebot-IA
Disallow: /private/
Disallow: /search

Allow GoogleScholar only on some folders

User-agent: Googlebot-IA
Allow: /blog/
Disallow: /

Allow GoogleScholar and block other crawlers

User-agent: Googlebot-IA
Allow: /

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

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

Who should care about GoogleScholar

Publishers

GoogleScholar brings search traffic, so keep the real one allowed. Fake GoogleScholar requests are a common cover for scrapers, so verify it by network rather than by name.

Media buyers and advertisers

Search crawlers fetch landing pages to check them. Keep GoogleScholar allowed, but out of campaign and conversion data.

Does GoogleScholar respect robots.txt?

We have not confirmed whether GoogleScholar 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 GoogleScholar?

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

Is robots.txt enough to block GoogleScholar?

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