According to Yahoo's official explanation, if we want to ban 6184.html "> Yahoo search site content, place a robots.txt file in our server's root directory, add the following:

User: *

Disallow:/

Since these are the standard protocols that most 11510.html "> Web search programs will follow, after joining these protocols, not only will Yahoo search not crawl the content of the site, but other search programs won't crawl our web servers or directories."

So the network wisdom to recommend you, should be careful to choose, we can write this:

User-agent:googlebot

Disallow:

User: *

Disallow:/

It is written that only a reptile named Googlebot can catch all the content of the site, and Yahoo Search and other search engine crawlers cannot crawl all the content of the site.

Or

User-agent:slurp

Disallow:/

Only to ban Yahoo's "slurp" search engine spiders crawl.
