Understanding Robots.txt User-agent Directive

What does the User-agent: * directive in a robots.txt file mean?

SEO Fundamentals

User-agent: *
Disallow: /private/

A It disables the robots.txt file entirely.

B It blocks only the Googlebot from accessing the site.

C It allows only one specific crawler to access the site.

D It applies the rules to all web crawlers visiting the site.

💡 Hint

Think about what the asterisk (*) symbol usually means in general contexts.

The User-agent: * directive targets all web crawlers, meaning the rules below it apply to every crawler visiting the website.

Effect of Disallow Directive

What is the effect of the following robots.txt snippet?

User-agent: *
Disallow: /admin/
Disallow: /tmp/

SEO Fundamentals

User-agent: *
Disallow: /admin/
Disallow: /tmp/

A All crawlers are allowed to access /admin/ and /tmp/ folders.

B All crawlers are blocked from accessing /admin/ and /tmp/ folders.

C Only Googlebot is blocked from /admin/ and /tmp/ folders.

D The robots.txt file is ignored by all crawlers.

💡 Hint

Look at the User-agent directive and the paths listed under Disallow.

The Disallow directive tells all crawlers (because of User-agent: *) not to visit the specified folders.

Interpreting Conflicting Rules in Robots.txt

Given the following robots.txt content, which statement is true about crawler access to /images/?

User-agent: Googlebot
Disallow: /images/

User-agent: *
Allow: /images/

SEO Fundamentals

User-agent: Googlebot
Disallow: /images/

User-agent: *
Allow: /images/

A All crawlers are allowed to access /images/.

B All crawlers are blocked from /images/.

C Googlebot is blocked from /images/, but other crawlers can access it.

D Googlebot and all other crawlers are blocked from /images/.

💡 Hint

Specific user-agent rules override general ones.

The rule for Googlebot specifically disallows /images/, while the general rule allows it for all other crawlers.

Difference Between Disallow and Allow Directives

Which of the following best describes the difference between Disallow and Allow directives in robots.txt?

A <code>Disallow</code> blocks crawlers from accessing paths; <code>Allow</code> permits access even if a broader <code>Disallow</code> exists.

B They are interchangeable and have the same effect.

C Both directives block crawlers but in different ways.

D <code>Allow</code> blocks crawlers; <code>Disallow</code> permits access.

💡 Hint

Think about how specific rules can override general ones.

Disallow tells crawlers not to visit certain paths. Allow can be used to permit access to sub-paths even if a parent path is disallowed.

Predicting Crawler Behavior with Complex Robots.txt

Consider this robots.txt file:

User-agent: *
Disallow: /

User-agent: Bingbot
Allow: /public/
Disallow: /public/private/

Which statement correctly describes Bingbot's access?

SEO Fundamentals

User-agent: *
Disallow: /

User-agent: Bingbot
Allow: /public/
Disallow: /public/private/

A Bingbot can access /public/ but not /public/private/; all other crawlers are blocked everywhere.

B Bingbot is blocked from the entire site including /public/; other crawlers can access /public/.

C Bingbot can access the entire site without restrictions.

D All crawlers including Bingbot are blocked from the entire site.

💡 Hint

Specific user-agent rules override general ones; Allow and Disallow can be combined.

The general rule blocks all crawlers everywhere. Bingbot has a specific rule allowing /public/ but disallowing /public/private/. So Bingbot can access /public/ except the private subfolder.
