网站排名与网站访问速度有什么关系或者联系吗

网站排名与网站访问速度有什么关系或者联系吗

前言:网站打开的快慢,在一定程度上影响着用户的流失率。据不完全统计网站打开时间超过3s,就有将近40%的用户会选择关闭。

因此,加载速度也成为了,搜索引擎排序中的一项因素。让我们一起看看有哪些优化点是我们值得关注的!为了更加直观的看到效果,我们来看一个案例: 
23989d1bc7a6e2d7ed84d96a9862bcd5.png


PS:这里load是指资源完全加载时间,不是指跟用户首屏交互时间

在上图数据可以发现: 从用户点击网站,到给用户呈现画面的过程,整体花了5.91s。其实这是非常糟蹋的加载速度了!那么有什么方法可以优化呢,让网站更快打开呢?

其实想要优化网站的打开速度,就应该从网站慢的原因入手。那就基本得了解从输入url到用户看到网页这个过程都发生了什么?大概流程如下:1、用户输入url 

2、浏览器对域名进行dns解析,获取到服务器ip地址。

3、客户端(浏览器)与服务器建立tcp连接,三次握手

4、握手成功后,发送请求,服务器处理相关逻辑,并把对应的数据返回给客户端(浏览器)

5、浏览器接受到数据,开始解析数据(HTML)

6、DOM树构建、CSS解析 Style Rules(CSS树)在这过程中,从上往下一直解析。如果碰到css样式(link、style)和 js脚本,会解析对应的样式或者脚本。此时会阻塞DOM元素构建

7、DOM树与CSS树生成呈现树,然后绘制页面,呈现给用户。(当然这里还有许多细节,暂时省略... 有兴趣朋友可自行了解)可能有人还是会问:就算我看懂了这个流程,可是我还是不知道怎么优化啊?到底要怎么操作呢?别着急,在爱收集资源认为,网站优化可以分为以下几部分:

一、网络优化

1、打开谷歌的debug调试工具 (F12)会弹出一个类似这样的窗口:

然后找到waterfall选项,有个进度条的东西。然后鼠标放上去,你就会看到如下图,例如:

ef696454f61ebceb0f1e2a70cd46f08b.png




由于上图有些参数,可能大家不知道,我来给大家讲解下:1、DNS Lookup DNS查询时间 [深绿色]2、Initial connection TCP连接消耗时间 [橙色]3、SSL SSL/TLS完成握手时间 [紫色]4、TTFB 是网络请求被发起到服务器返回第一个字节所花费的时间 [绿色]5、Content Download 文档下载时间 [蓝色]那么知道上述几个参数有什么含义呢? 比如:如果你发现网站资源加载非常多,拖慢了网站加载时间,怎么解决呢?

1、可以合并资源,减少http请求。 比如:js、css合并,小图片合成雪碧图... 
2、分域名加载资源,突破浏览器限制(因为在同源资源加载的情况下,浏览器最多允许同时6个请求加载)或者利用HTTP2.0多路复用
3、减少DNS lookup时间,提前解析DNS 比如:
html head中添加link标签: 

二、 前端优化

1、如果追求首屏优化,比如:电商这种行业。可以把首屏css样式写入head头中,减少http请求次数,让首屏更快的渲染。淘宝为例:



2、静态资源压缩打包走cdn,减少主服务器的压力,然资源加载的更换。(因为cdn公司的服务器节点比你服务器更加靠近用户)3、根据具体情况,把js设置异步延迟加载,减少阻止dom渲染时间。比如

具体细节优化,可以看这篇文章 你了解过前端怎么优化吗?

 三、服务端优化


1、开启服务端缓存,减少服务器压力。

2、开启gzip压缩,减少资源大小,传输更快。

3、数据做好缓存和优化,减少服务端IO操作

写在最后:当然网站的优化有很多方面,但这篇文章只是从技术的角度去谈,并未结合SEO和营销的角度去讲解。往往我们很多时候,只是看到事物的表面,对于底层和细节而被忽略。出了问题,一定得要从根源入手,才能解决根本问题。

Cool website!

My name’s Eric, and I just found your site - luluzyw.com - while surfing the net. You showed up at the top of the search results, so I checked you out. Looks like what you’re doing is pretty cool.

But if you don’t mind me asking – after someone like me stumbles across luluzyw.com, what usually happens?

Is your site generating leads for your business?

I’m guessing some, but I also bet you’d like more… studies show that 7 out 10 who land on a site wind up leaving without a trace.

Not good.

Here’s a thought – what if there was an easy way for every visitor to “raise their hand” to get a phone call from you INSTANTLY… the second they hit your site and said, “call me now.”

You can –
  
Talk With Web Visitor is a software widget that’s works on your site, ready to capture any visitor’s Name, Email address and Phone Number.  It lets you know IMMEDIATELY – so that you can talk to that lead while they’re literally looking over your site.

CLICK HERE https://talkwithwebvisitors.com to try out a Live Demo with Talk With Web Visitor now to see exactly how it works.

Time is money when it comes to connecting with leads – the difference between contacting someone within 5 minutes versus 30 minutes later can be huge – like 100 times better!

That’s why we built out our new SMS Text With Lead feature… because once you’ve captured the visitor’s phone number, you can automatically start a text message (SMS) conversation.
  
Think about the possibilities – even if you don’t close a deal then and there, you can follow up with text messages for new offers, content links, even just “how you doing?” notes to build a relationship.

Wouldn’t that be cool?
