前2天,google官方blog發(fā)布1篇小文章,該文章指出將把 "網(wǎng)站的訪問速度" 加入搜索排名算法中,說明以后網(wǎng)站越快,在google中的排名就越有可能靠前。
該文章地址:

因該blog好像在國內(nèi)訪問不了(不知道是否和諧了),所以把部分內(nèi)容帖出來:
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.
同時(shí)該blog還推薦幾款免費(fèi)的測(cè)試網(wǎng)站性能的工具:
1.
page speed : page speed 是1個(gè)開源的 firefox\firebug插件,用于評(píng)價(jià)你的網(wǎng)站的性能,并給出性能提升建議.
2.
yslow : yslow跟pge speed一樣是基于 firefox\firebug的插件,功能與page speed類似,對(duì)各種影響網(wǎng)站性能的因素進(jìn)行評(píng)分,yslow是yahoo的工具,本人也一直在使用,推薦一下。
3、
webpagetest : webpagetest 是1個(gè)在線進(jìn)行性能測(cè)試的網(wǎng)站,在該網(wǎng)站輸入你的url,就會(huì)生成1個(gè)url加載的時(shí)間瀑布圖,對(duì)所有加載的資源(css,js,image等等)列出優(yōu)化的清單,也是非常好用的工具。
4、最后推薦的當(dāng)然是google自己的
webmasters tools : 登錄webmasters 后,選擇 Labs > Site Performance 就可以看到你網(wǎng)站的性能。
其實(shí)這樣的工具有很多,而且不同的瀏覽器工具還不太一樣,有時(shí)間把自己用過的工具都整理下推薦給大家。
PS: 該blog的最后還提到了,"網(wǎng)站速度" 是剛加入搜索引擎中的排名因子,所以開始占的比例不會(huì)很高,可能還不到1%。當(dāng)說明現(xiàn)在網(wǎng)站的速度越來越被重視了。
