Why it matters
It can manage crawler traffic and explicitly allow or disallow supported agents, but it is not an access-control or confidentiality mechanism.
How to use it
Keep public CSS, JavaScript, images, and canonical content crawlable; use the correct user-agent names; test the file; use noindex or authentication for different goals.
Limits and interpretation
Respect depends on the crawler. A disallowed URL can still be indexed without content if linked elsewhere, and private data must never rely on robots.txt protection.
Common mistakes
Blocking rendering assets; using robots.txt to hide secrets; inventing crawler names; blocking search discovery while expecting citations.
