How does Google decide between Allow and Disallow?

Google uses the most specific matching rule, which is the one with the longest path pattern. If an Allow and a Disallow rule are equally long, the less restrictive Allow rule wins.

Which group applies to my crawler?

The crawler follows the group whose user-agent matches its name exactly (case-insensitive). If several groups name it, their rules are combined. If none do, the * group applies.

What do * and $ mean?

* matches any sequence of characters, and $ at the end of a pattern means the URL must end there. For example, Disallow: /*.pdf$ blocks every URL ending in .pdf.

Why can't the tool fetch robots.txt from my site?

Browsers block web pages from reading files on other domains unless that site allows it (CORS). Paste the file content instead — nothing is uploaded.

Does blocking a URL in robots.txt remove it from Google?

No. robots.txt controls crawling, not indexing. A blocked URL can still appear in results if other pages link to it. Use a noindex meta tag on a crawlable page to keep it out of the index.

Does Google support crawl-delay?

No, Googlebot ignores crawl-delay. Some other crawlers, such as Bingbot, do support it.
