PR值是什么

PR值全称为PageRank,是谷歌对网页的评级,级别分别是0到10,是Google用于评测一个网页“重要性”的一种方法。

PR值Google排名运算法则(排名公式)的一部分,用来标识网页的等级/重要性。级别从0到10级,10级为满分。PR值越高说明该网页越受欢迎(越重要)。例如:一个PR值为1的网站表明这个网站不太具有流行度,而PR值为7到10则表明这个网站非常受欢迎(或者说极其重要)。

Pr值是谷歌对网页重要性的评估,其对谷歌的影响比其他搜索引擎重要。


我们还要知道的是,pr值受众多因素的影响,如收录数量、导入链接、导出链接、更新内容等等。

可以这样说:一个网站的外部链接数越多其PR值就越高;外部链接站点的级别越高,网站的PR值就越高。


例如:如果A网站上有一个B网站的外链资源,那为B 网站必须提供一些较好的网站内容,从而Google会把来自A的链接作为它对B网站投的一票。你可以下载和安装Google工具条来检查你的网站级别(PR值),或者利用工具也可以查询PR值。


然而,很多站长只看重了pr值的高低,甚至误认为pr值高的网站权重就一定高,因而在交换链接和发布链接诱饵时走入了盲目崇拜pr值的误区。

如何提高PR值

1、增加网站内容质量,不仅要保持原创性,而且要保证质量。良好的内容不仅有利于用户体验,而且有助于提升搜索引擎对网站友好度、内容的收录和网站权重。

2、登录搜索引擎和分类目录、友情链接,如果能获得来自PR值不低于4并与你的主题相关或互补的网站的友情链接,且很少导出链接,那样效果更好。

3、写一些高质量的软文,发布到大型网站,如果得到大家的认可,你的网址会被无数的网站转载,这种方法对于提高PR值效果最好、

4、搜索引擎收录一个网站的页面数量,如果收录的比例越高,对提高PR值越有利。

5、提供有价值的网站内容,并进行SEO优化,对提高PR值也非常的重要。

6、最好使网站被三大知名网络目录DMOZ,Yahoo和Looksmart收录,如果能被收录,对PR值的提高非常的迅速.

7、与高PR值网站链接,最好找同行业网站进行友情链接,其次要防止链接欺骗以及PR值劫持的网站。
