<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><strong style="color: blue;">前言：</strong>这是白杨SEO公众号原创第<strong style="color: blue;"><span style="color: black;">179</span></strong>篇。在白杨SEO实战培训课里有一堂<span style="color: black;">基本</span>课，<span style="color: black;">部署</span>作业即认识<span style="color: black;">各样</span>搜索引擎蜘蛛与网站HTTP状态码，今天就来分享一下，给SEO新人看一看。</span></p><img src="https://mmbiz.qpic.cn/mmbiz_png/8hvibvgH0421tWESBoicCFVv8Hc1jqTonalmbHlwLNeJLj2ia11NPcpwoOYjlPO64meBd58QuEXqDDS1Nsd9AhIZg/640?wx_fmt=png&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;">
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">缘由：</span></strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">不知不觉，本公众号更新原创近200篇了。我的实战培训<span style="color: black;">亦</span>举行完三期了，第四期因个人<span style="color: black;">原由</span>有事暂停。关于SEO<span style="color: black;">基本</span><span style="color: black;">亦</span>写了几十篇公众号，一个<span style="color: black;">伴侣</span>介绍我<span style="color: black;">能够</span>把<span style="color: black;">基本</span>实战整理出书，在<span style="color: black;">思虑</span>中。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">关于SEO<span style="color: black;">基本</span><span style="color: black;">文案</span>，白杨SEO公众号菜单栏点【SEO入门教程】<span style="color: black;">就可</span>查看，今天再补一篇。正如前言所写，这是很<span style="color: black;">基本</span>的，但这个<span style="color: black;">基本</span>并不是人人都很清楚，<span style="color: black;">因此</span>写下哈。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">搜索引擎及搜索引擎蜘蛛是什么？</span></strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">我在实战培训<span style="color: black;">第1</span>课讲搜索引擎基本工作原理时，都会给新人讲搜索引擎是什么，<span style="color: black;">而后</span>再来讲，搜索引擎蜘蛛是什么。<span style="color: black;">那样</span>，在<span style="color: black;">这儿</span>再讲一下。<span style="color: black;">重点</span><span style="color: black;">归类</span>如下：</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">1、按国内与国外分</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">国内：</span><span style="color: black;">百度、搜狗、360、神马（UC）、头条等；</span><span style="color: black;">国外：</span><span style="color: black;">google、bing、yahoo、yandex(俄罗</span>斯<span style="color: black;">)等。</span></span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">2、按PC与移动端分</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">PC：google、bing、yahoo、百度、搜狗、360</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">移动：神马、头条</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">PC+移动都有：<span style="color: black;">google、bing、yahoo、百度、搜狗</span></span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">当然除了上面介绍的通用搜索引擎，其实还有<span style="color: black;">有些</span>垂直的搜索引擎。<span style="color: black;">例如</span>像搜文库的豆丁网，搜索工作的职友集等等。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;">各个搜索引擎蜘蛛是什么？</span></strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">这儿</span>的【蜘蛛】非生活现实中的蜘蛛，<span style="color: black;">咱们</span>只是把搜索引擎去爬取各网页内容那个代码<span style="color: black;">咱们</span>形象的<span style="color: black;">叫作</span>它为蜘蛛。各个搜索引擎蜘蛛写法如下：</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><img src="https://mmbiz.qpic.cn/mmbiz_png/8hvibvgH0421tWESBoicCFVv8Hc1jqTonaNdicpfum53AW0R4BWKscC9ibq1icBic535p79jwvhaUKFyJoYCo9SBibibJg/640?wx_fmt=png&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;"></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><img src="https://mmbiz.qpic.cn/mmbiz_png/8hvibvgH0421tWESBoicCFVv8Hc1jqTona82Nhq7IKUlDXveZQr81mIrSPLP0ia0WiaSib4ia595DN46ticYdBT9EV40Q/640?wx_fmt=png&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;"></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;"><span style="color: black;"><span style="color: black;">怎样</span>识别百度搜索引擎蜘蛛呢？</span></strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">其实，<span style="color: black;">非常多</span>新人SEO<span style="color: black;">朋友</span>很少接触到搜索引擎蜘蛛，即使百度蜘蛛<span style="color: black;">亦</span>未必能接触到。即使接触到了，<span style="color: black;">亦</span>不<span style="color: black;">晓得</span>它是不是。<span style="color: black;">为何</span>呢？<span style="color: black;">由于</span><span style="color: black;">非常多</span>SEO新人<span style="color: black;">无</span>分析网站日志，所以没看到。</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">倘若</span>你有分析过网站日志的话，就应该见过百度蜘蛛了（baiduspider）。</p>
<span style="color: black;"><span style="color: black;">日前</span>百度UA（useragent简<span style="color: black;">叫作</span>，即用户）分为移动、PC、和小程序三个应用场景来访，这三个<span style="color: black;">途径</span>UA分别如下：</span><strong style="color: blue;"><span style="color: black;">移动UA：</span></strong><span style="color: black;">Mozilla/5.0(Linux;u;Android4.2.2;zh-cn;)AppleWebKit/534.46 (KHTML,likeGecko)Version/5.1MobileSafari/10600.6.3</span><span style="color: black;">(compatible;Baiduspider/2.0;</span><span style="color: black;">+http://www.baidu.com/search/spider.html)</span><span style="color: black;">

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">例如</span>，<span style="color: black;">倘若</span>一个网站有<span style="color: black;">海量</span>的404页面的话，其实对搜索引擎<span style="color: black;">亦</span>不友好，<span style="color: black;">通常</span><span style="color: black;">意见</span>是制作成txt<span style="color: black;">或</span>xml提交到百度站长平台后台。</p><img src="https://mmbiz.qpic.cn/mmbiz_png/8hvibvgH0421tWESBoicCFVv8Hc1jqTonavwOm4EQ0dE6dCkq3dPZFtiaAic5MjsibPFriaVicia4zGBJNUfHHibvv5v9ag/640?wx_fmt=png&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;"><span style="color: black;">
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">再<span style="color: black;">例如</span>，打开网站<span style="color: black;">表示</span>502<span style="color: black;">或</span>503的话，就要赶紧联系你的技术了。<span style="color: black;">非常多</span>人以为网站偶尔打不开很正常，殊不知，这在做SEO里是大忌！</p>
</span><span style="color: black;">
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">真实案例，我以前前前<span style="color: black;">机构</span>一个同事来问我，说自己网站连续更新了两个月了，<span style="color: black;">为何</span>百度还没收录？我让他把网址发我看一看。我试了各个浏览器很久打不开，问他说那边服务器问题，让我<span style="color: black;">次日</span>再<span style="color: black;">瞧瞧</span>。</p>
</span><span style="color: black;">
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">其实做为SEO新人的你可能不<span style="color: black;">晓得</span>，但假想一下，你是那个潜在用户，去<span style="color: black;">拜访</span>一个网站打不开的话是不是马上就关掉走了呢。而百度从关键词<span style="color: black;">关联</span>到外链再到<span style="color: black;">此刻</span>用户体验为核心，<span style="color: black;">因此</span>懂了吧。</p>
