在Apache、IIS6、IIS7独立IP主机上屏蔽拦截蜘蛛抓取的方法如下： 1. Apache服务器：在httpd.conf文件中添加以下代码： ``` SetEnvIfNoCase User-Agent "^Mozilla/5.0\s\(compatible;\sGooglebot/2.1" bad_bot SetEnvIfNoCase User-Agent "^Mediapartners-Google" bad_bot SetEnvIfNoCase User-Agent "^Everflux" bad_bot Order Allow,Deny Allow from all Deny from env=bad_bot ``` 2. IIS6服务器：使用ISAPI_Rewrite插件，创建一个规则，如下： ``` RewriteCond %{HTTP_USER_AGENT} (Googlebot|bingbot|Yahoo! Slurp) [NC] RewriteRule .* - [F,L] ``` 该规则将针对Googlebot、Bingbot和Yahoo! Slurp等蜘蛛用户代理，将其拒绝访问。 3. IIS7服务器：在web.config文件中添加以下代码： ``` ``` 该规则将对Googlebot和Bingbot等蜘蛛用户代理进行拦截，并返回403状态码，拒绝访问。

如果快照显示网页不完整，是不是说明BaiduSpider没有完整收录网页？

不一定，BaiduSpider 可能没有完整收录网页，也可能完整收录但快照却不完整。例如，某个网页上的脚本可能没有加载完成，这样就可能造成快照显示不完整，又或者，BaiduSpider完整把网页收录了，但是Baidu在生成快照时，出现了问题，导致快照不完整。

网站抓取了一些不存在的目录跟页面?

1. 重新编辑robots.txt文件，将网站中不需要抓取的页面和目录添加进去； 2. 如果抓取的网站带有反爬虫功能，建议可以设置User-Agent，以区分人为访问和爬虫程序进行访问； 3. 设置深度抓取，让程序对某个网页进行抓取时，只抓取它指定难度及深度的URL； 4. 不定时发起网站扫描任务，用来检查异常的URL，以及分析抓取URL的情况，同时将发现的问题处理掉； 5. 合理设置

搜索引擎蜘蛛劫持是什么？怎么判断是否被劫持

威海Spider 威海Spider
2495

搜索引擎蜘蛛劫持是seo黑帽中常用的一种手法,需要一定的技术支持getshell,然后上传恶意的代码到网站根目录下面或者修改网站的一些文件，搜索引擎蜘蛛劫持的原理就是判断来访网站的是用户还是蜘蛛,如果是蜘蛛就推送一个事先准备的恶意网站,如果是用户就推送一个正常的网页1：蜘蛛判断判断访问的是用户还是蜘蛛,如果是用户就推送一个正常网页,如果是蜘蛛就推送一个恶意网页，判断方式有两种,一种是判断蜘蛛的UA
