屏蔽Semrush、Ahrefs等恶意垃圾蜘蛛爬虫加速网站访问

admin   ·   发表于 4个月前   ·   SEO优化

对于SEMrush蜘蛛来说,我们感觉目前没多大用处,另考虑到占用服务器资源,我们决定屏蔽掉。另外还有几个蜘蛛根据情况来屏蔽:

1、MJ12Bot

MJ12Bot 是英国著名SEO公司Majestic的网络爬虫,其抓取网页给需要做SEO的人用,不会给网站带来流量。

2、AhrefsBot

AhrefsBot 是知名SEO公司Ahrefs的网页爬虫。其同样抓取网页给SEO专业人士用,不会给网站带来流量。

3、SEMrushBot

SEMrushBot 也是SEO、营销公司的网络爬虫。

4、DotBot

DotBot 是 Moz.com 的网页爬虫,抓取数据用来支持 Moz tools 等工具。

5、MauiBot

MauiBot 不同于其他爬虫,这个爬虫连网站都没有,UA只显示一个邮箱:”MauiBot ([email protected] ail.com)“。神奇的是这个看起来是个人爬虫,竟然遵循robots协议,算得上垃圾爬虫的一股清流。

6、MegaIndex.ru

这是一个提供反向链接查询的网站的蜘蛛,因此它爬网站主要是分析链接,并没有什么作用。遵循robots协议。

7、BLEXBot

这个是webmeup下面的蜘蛛,作用是收集网站上面的链接,对我们来说并没有用处。遵循robots协议。


首先因为这个蜘蛛爬行并不会给网站带来流量,只会占用服务器资源,其次是这是已经数据分析公司的爬虫,它爬的数据会成为你竞争对手的分析利器。

1、通过robots.txt禁止

User-agent: SemrushBot

Disallow: /

User-agent: Semrushbot-SA

Disallow: /

User-agent: Semrushbot-SI

Disallow: /

User-agent: AhrefsBot

Disallow: /

User-agent: DotBot

Disallow: /

User-agent: MegaIndex.ru

Disallow: /

User-agent: MauiBot

Disallow: /

User-agent: MJ12bot

Disallow: /

User-agent: BLEXBot

Disallow: /


2、web层面通过UA禁止

对于不遵循robots协议的爬虫,可以在web软件层面通过UA屏蔽。下面以 Nginx 为例介绍,操作为:在网站配置的server段内,新增类似如下指令:

server {

   ... 一些网站配置

   # 屏蔽curl/httpclient抓取

   if ($http_user_agent ~* curl|httpclient) {

     return 403;

   }

   # 屏蔽MauiBot等爬虫

   if ($http_user_agent ~* MauiBot|AhrefsBot|DotBot) {

     return 403;

   }

   ... 其他配置


至于一共有哪些搜索引擎爬虫或者蜘蛛,国外也进行了收集,如下
