前2天,google官方blog发布1篇小文章,该文章指出将把 "网站的访问速度" 加入搜索排名算法中,说明以后网站越快,在google中的排名就越有可能靠前。
该文章地址:

因该blog好像在国内访问不了(不知道是否和谐了),所以把部分内容帖出来:
You may have heard that here at Google we're obsessed with speed, in our products and on the web. As part of that effort,
today we're including a new signal in our search ranking algorithms: site speed. Site speed reflects how quickly a website responds to web requests.
Speeding up websites is important — not just to site owners, but to all Internet users. Faster sites create happy users and we've seen in our internal studies that when a site responds slowly, visitors spend less time there. But faster sites don't just improve user experience; recent data shows that improving site speed also reduces operating costs. Like us, our users place a lot of value in speed — that's why we've decided to take site speed into account in our search rankings. We use a variety of sources to determine the speed of a site relative to other sites.
同时该blog还推荐几款免费的测试网站性能的工具:
1.
page speed : page speed 是1个开源的 firefox\firebug插件,用于评价你的网站的性能,并给出性能提升建议.
2.
yslow : yslow跟pge speed一样是基于 firefox\firebug的插件,功能与page speed类似,对各种影响网站性能的因素进行评分,yslow是yahoo的工具,本人也一直在使用,推荐一下。
3、
webpagetest : webpagetest 是1个在线进行性能测试的网站,在该网站输入你的url,就会生成1个url加载的时间瀑布图,对所有加载的资源(css,js,image等等)列出优化的清单,也是非常好用的工具。
4、最后推荐的当然是google自己的
webmasters tools : 登录webmasters 后,选择 Labs > Site Performance 就可以看到你网站的性能。
其实这样的工具有很多,而且不同的浏览器工具还不太一样,有时间把自己用过的工具都整理下推荐给大家。
PS: 该blog的最后还提到了,"网站速度" 是刚加入搜索引擎中的排名因子,所以开始占的比例不会很高,可能还不到1%。当说明现在网站的速度越来越被重视了。
