上一篇文章里面给大家简单说明什么是百度索引量,以及影响百度索引量下降原因有三点,具体的内容:【导致百度索引量下降的常见原因(1)】。影响百度索引量下降还有三种原因。

导致百度索引量下降的常见原因(2)

四、内容数据与所在的网址URL规范不统一

网站上多个域名都以200状态正常访问网页内容,而在单个域名下出现多种URL形式可以访问相同内容,比如:大小写URL、URL规则变更等。

建议确定网站的主域名,将其他域名下的URL设置301重定向到主域名上。

五、入库的URL对蜘蛛不友好

1)robots禁止蜘蛛抓取

可以通过百度站长工具查看robots抓取情况。

2)URL规则发生变动,原本的URL无法访问

URL规则发生变动可能会出现大小写URL。URL必须设置301重定向,在站长工具上提交改版需求。

3)显示错误页面

一个网站呈现的页面有过多的死链接,搜索引擎认为影响用户的访问体验和点击率,影响网站其他正常页面的抓取和索引。可以通过百度站长平台死链工具。

4)网站被黑

防止URL对蜘蛛进行非法跳转操作,URL对应的网页内容对蜘蛛出现违法乱纪的内容。

六、DNS和服务器

1)网站可访性差

百度搜索引擎通常从三大方面来判断网页可访问性,分别为:正常访问的网页、有权限限制的网页、已经失效的网页。

2)屏蔽百度UA和IP

使用百度站长工具,定期查看百度抓取页面的情况。
