My site has heavy traffic because some bot. I checked access_log, some bot Baiduspider go to my site 10-20 times per minute. I do not need Chinese traffic. I have searched and read http://www.baidu.com/search/robots_english.html

I added rule into the robots.txt then restarted Aache, but it doesn't work. Baiduspider still crawls my site.

User-agent: Baiduspider
Disallow: /

User-agent: *
Disallow: /feed/
Disallow: /trackback/
Disallow: /wp-admin/
Disallow: /wp-includes/
Disallow: /xmlrpc.php

I found their feedback page http://zhanzhang.baidu.com/feedback/index I can translate the page to my language, but I cannot translate and insert captcha.

Then I have searched and find some article: http://www.askapache.com/htaccess/blocking-bad-bots-and-scrapers-with-htaccess.html But when I add it into .htaccess, I cannot access my site,(you do not have permission to access this site) Am i inserted in a wrong position? need a help.

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /

RewriteCond %{HTTP_USER_AGENT} ^Baiduspider.* [NC,OR]
RewriteRule ^.* - [F,L]

#some custom rewrite rule
RewriteRule ^article/([^/\.]+)/?$ /article/$1.php [L,QSA]

RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

BTW, my server is CentOS7 apache 2.4.6. I also tried "httpd.conf", but I never find any article about apache 2.4.6 <IfModule setenvif_module>, all the articles are <IfModule mod_setenvif_c>... apache 2.4.6 do cancel order allow,deny rule, I have no idea how to modify and add into my httpd.conf.

Anyway, I just want to refuse Baiduspider Thanks.

  • Baidu is often fairly well behaved. It is possible that since Baidu is a Japanese/Chinese search engine mostly from China, that some scrapers are using the agent name and going rogue. This may be what you are seeing. Otherwise, this is something I need to look into further. – closetnoc Jan 7 '15 at 16:37

You can try blocking specific IP addresses in your .htaccess file. You can find the ranges here.

In robots.txt you can also add the following

User-agent: Baiduspider
User-agent: baiduspider
User-agent: Baiduspider+ 
User-agent: Baiduspider-video
User-agent: Baiduspider-image
Disallow: /

Also, if you use caching plugins or CDN, make sure to clear all your cache.

    Only the first User-agent: Baiduspider should be necessary to block all Baidu spiders ("a case insensitive substring match" according to the "standard" and Baidu reportedly supports the "standard"). And this is stated in the Baidu help docs. However, it can take some days for the spider to pick up the change to robots.txt – MrWhite Dec 8 '16 at 17:17

I think the problem with your rewrite rule is the OR flag. That flag usually means that there is a second rewrite condition coming. You only have one condition.

Here is a site that provides a similar rule for blocking BaiduSpider with slightly different syntax:

RewriteEngine On
RewriteCond %{HTTP_USER_AGENT} ^Baiduspider.* [NC]
RewriteRule .* - [F]
