[seo外链]网站无效、空白等页面对seo的危害及处理

小鱼seo 959 0

  首先,我们需要了解什么是无效页面?无效页面是指对搜索引擎而言没有索引价值,或对用户来说没有任何价值、无用户需求的页面。这些页面包括注册页、无内容页面、登录页等等,用户不需要的或重复的页面,也包括广告太多的页面。

  网站在建设和维护过程中,会产生哪些可能的无效页面?这些无效页面对老站和新站来说,受到的影响分别是什么呢?空页面及无内容的页面针对新站,会直接影响其权重、收录和排名。如果新站的这些无内容页面被百度收录,在1-2周内没有解决掉,搜索引擎很可能会判断该站为劣质网站。

  对老站的影响虽然没有这么严重,但也是不容忽视的,不仅会影响到整站的内容质量,更重要的是会降低用户体验。如果老站出现大量的无内容页面,轻者会被百度扣分,严重的会被降权处理。此时只有把这些无效页面,采用搜索引擎认可的方法,予以有效的处理或屏蔽,才能使搜索引擎恢复对网站的信誉。

  对于网站优化无效页面处理的法则,简小白针对不同的类别,总结出了四种处理无效页面的方法。

  第一种方法也是最简单的方法,就是人工处理的方法,即对无内容页面添加一些内容。如有些产品类网站按用户需求来定位,根据不同的地区或不同的类型,做了很详细同时也很繁杂的分类,而很多分类里面暂时没有产品,就会导致很多无内容空白页面的产生。此时最好的处理方法是,不要给予这些页面入口,等到后期这些页面的产品上架后,再给予入口。

  第二种方法是针对用户需要,但对搜索引擎没有索引价值的页面。这些页面包括咨询页面、注册页面、登录页等,这些信不需要被搜索引擎抓取,也对排名没有任何贡献值。这些页面虽然是被用户或网站本身业务所需要,但用户的信息是不能被抓取的,而且索引价值也非常低。最好的方法是用robots.txt文件进行屏蔽,屏蔽代码为Disallow:/member.php。

  第三种是对相对性无效页面的处理。这里所说的相对性无效页面,包括商品购物车购物页、个人的信息资料页面、博客的留言评论等。特别是博客的留言评论页面,虽然是有用户需求的页面,但如果不采取措施,难以避免的会出现推广人员制造的,或用户无意制造的大量垃圾导出链接,这些链接不仅会导致权重的流失,而且大部分是不被信任的链接,此时可以针对这些页面采用rel=”nofollow”处理。

  第四种是对大量重复页面的处理。对产品站而言这些重复页面,包括同产品多型号公用页面,或产品不同内容是一样的重复内容页面。这些页面的存在相当于是,网站在不停的制造重复内容,是极不利于搜索引擎优化的行为。对这些页面的处理法则是做canonical处理,即在
