用DIV+CSS的网页布局对SEO的好处_html/css_WEB-ITnose

DIV+CSS是网站标准(或称“WEB标准”)中常用术语之一,通常为了说明与HTML网页设计语言中的表格(table)定位方式的区别,因为XHTML网站设计标准中,不再使用表格定位技术,而是采用DIV+CSS的方式实现各种定位。

SEO是指搜索引擎优化,主要就是通过对网站的结构、标签、排版,关键字等各方面的优化,使搜索引擎更容易抓取网站的内容,并且让网站的各个网页在等搜索引擎中获得较高的评分,从而获得较好的排名。DIV+CSS网页布局对SEO有很重要的影响。具体来看到底有什么好处呢?


    DIV+CSS的网页布局对SEO的好处一、不存在表格的嵌套问题

很多“网站如何推广”的文章中称,搜索引擎一般不抓取三层以上的表格嵌套,这一点一直没有得到搜索引擎相关的官方证实。我的几项实验结果没有完全出来,但 根据目前掌握的情况来看,Spider爬行Table布局的页面,遇到多层表格嵌套时,会跳过嵌套的内容或直接放弃整个页面。

使用Table布局,为了达到一定的视觉效果,不得不套用多个表格。如果嵌套的表格中是核心内容,蜘蛛(Spider)爬行时跳过了这一段没有抓取到页面的核心,这个页面就成了相似页面。网站中过多的相似页面会影响排名及域名信任度。

DIV+CSS的网页布局对SEO的好处二、精简的代码

使用DIVCSS布局,页面代码精简,这一点相信对XHTML有所了解的都知道。观看更多的HTML教程内容。

代码精简所带来的直接好处有两点:一是提高蜘蛛(Spider)爬行效率,能在最短的时间内爬完整个页面,这样对收录质量有一定好处;二是由于能高效的爬行,就会受到蜘蛛(Spider)欢迎,这样对收录数量有很大好处。


而DIV+CSS布局基本上不会存在这样的问题,从技术角度来说,XHTML在控制样式时也不需要过多的嵌套。

这虽然没有得到确认,但还是建议使用Table布局的朋友们,在设计时尽可能的不要使用多层表格嵌套,SEOer(seo工作者们)们在文章中说明了这一点,相信他们也不是没有依据。

    DIV+CSS的网页布局对SEO的好处三、对搜索引擎的排名

基于XTHML标准的DIV+CSS布局,一般在设计完成后会尽可能的完善到能通过W3C验证。截止目前没有搜索引擎表示排名规则会倾向于符合W3C标准的网站或页面,但事实证明使用XTHML架构的网站排名状况一般都不错。

DIV+CSS的网页布局对SEO的好处四、提高网页的访问速度

DIV+CSS布局较Table布局减少了页面代码,加载速度得到很大的提高,这在蜘蛛(Spider)爬行时是非常有利的。过多的页面代码可能造成爬行超时,蜘蛛(Spider)就会认为这个页面无法访问,影响收录及权重。

   真正的SEOer(seo工作者们)不只是为了追求收录、排名,快速的响应速度是提高用户体验度的基础,这对整个搜索引擎优化及营销都是非常有利的。

换一个角度抛开DIV+CSS对SEO的有利影响.单独来讲这种div+css布局也是很有益的,可以说是实下是最流行的网页布局方式.可是加快我们网站的速度,便于管理与修改.当然div+css布局也有不完善的方面,比如说,他的css样式表与各种浏览器之间的不兼容问题.当然如果你是div+css高手的话相信这个不难吧!

SEO是由英文Search Engine Optimization缩写而来, 中文意译为“搜索引擎优化”。SEO是指通过对网站内部调整优化及站外优化,使网站满足搜索引擎收录排名需求,在搜索引擎中提高关键词排名,从而把精准用户带到网站,获得免费流量,产生直接销售或品牌推广。
