<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">从上上周<span style="color: black;">起始</span>,<span style="color: black;">制品</span>团队每周都会请一位小伙伴给<span style="color: black;">大众</span>做分享,主题不限,以自己<span style="color: black;">善于</span>或感兴趣的方向为出发点,旨在<span style="color: black;">熬炼</span><span style="color: black;">大众</span>的总结表达能力,并拓展自己负责<span style="color: black;">制品</span>工作外的视野。<span style="color: black;">例如</span>之前给<span style="color: black;">大众</span>介绍的这篇:<a style="color: black;">基于内容<span style="color: black;">类似</span>度的<span style="color: black;">举荐</span>算法简介</a>,来自团队实习生小姐姐,上周是我分享的《谷歌<span style="color: black;">办法</span>》导读,<strong style="color: blue;">这周则<span style="color: black;">是由于</span><span style="color: black;">咱们</span>负责36氪Web主站的<span style="color: black;">制品</span>大哥,给<span style="color: black;">大众</span>普及SEO的<span style="color: black;">有些</span><span style="color: black;">基本</span>知识</strong>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">咱们</span>这位Web主站负责人对SEO还是<span style="color: black;">特别有</span>发言权的,他有着10年的运营经验,曾在中搜干了6年,专门负责搜索<span style="color: black;">关联</span>的运营工作,36氪当下的SEO工作<span style="color: black;">亦</span>是他来负责。虽然我<span style="color: black;">亦</span>有<span style="color: black;">有些</span>零碎的搜索知识,但这次分享着实让我开了眼界,接下来就挑<span style="color: black;">有些</span>重要知识点和你聊聊。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">SEO,是搜索引擎优化的简<span style="color: black;">叫作</span>,做SEO的目的,<strong style="color: blue;">一是为了让<span style="color: black;">更加多</span>人<span style="color: black;">发掘</span>自己的网站,二是要<span style="color: black;">协同</span>SEM做互联网营销推广,三则是为了从竞争对手那里掠夺用户。</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">评定</span>一家网站SEO水平<span style="color: black;">怎样</span>,<strong style="color: blue;">PR值(PageRank)</strong>是比较重要的指标,PR越高搜索出结果的权重排序越靠前。其理论公式如下:</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">PR(A) =(PR(B) /L(B)+PR(C) /L(C)+PR(D)/L(D)+...+PR(N)/L(N))q+1-q</p>PR(B)、PR(C)...PR(N)<span style="color: black;">暗示</span>链接到⽹页A的N个⽹⻚的PR等级。N是链接的总数,这个链接<span style="color: black;">能够</span>是来自任何网站的导入链接(反向链接)L(N)<span style="color: black;">暗示</span>网页N导出向其他网站链接的数量q是阻尼系数,介于0-1之间,Google设为0.85<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">亦</span><span style="color: black;">便是</span>说,导向你网站的链接越多,导出链接越少,你的PR就越高。国际上做SEO都以Google的PR计算规则为参考,<strong style="color: blue;">但在我国则要重点关注度娘</strong>。百度的PR规则相比Google更<span style="color: black;">繁杂</span>,<span style="color: black;">况且</span>每年都会变个几次,很难精确估算,但<span style="color: black;">亦</span>有<span style="color: black;">有些</span>公开标准可参考,<span style="color: black;">通常</span>来讲影响百度权重的<span style="color: black;">原因</span>有这么几个:</p>网站外链的推广度、数量和质量网站的内链够强⼤网站的原创质量网站的年龄时间网站的更新频率网站的流量,流量越高网站权重越高网站的关键词排名:关键词排名越靠前,网站的权重越⾼网站的收录数量:网站百度收录数量越多,百度权重越⾼网站或⽹⻚的浏览量及深度:即⽤户体验越好,百度权重越⾼。关键词的数量:关键词的数量越多,<span style="color: black;">累积</span>的权重<span style="color: black;">亦</span>会越高,<span style="color: black;">不外</span>,这还要看关键词的流量,<span style="color: black;">倘若</span>关键词的流量⾮常低,即便排名很靠前,权重<span style="color: black;">亦</span>不会<span style="color: black;">累积</span>到<span style="color: black;">非常多</span>,<span style="color: black;">不外</span><span style="color: black;">能够</span>积少成多。<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">在百度算法中,判断<span style="color: black;">是不是</span>收录和判断给予多高权重是完全独立的两个算法。<strong style="color: blue;">典型错误思想是:收录快=权重高</strong>。百度的收录速度是<span style="color: black;">按照</span>你<strong style="color: blue;">⽹站的更新频率和内容<span style="color: black;">鲜嫩</span>度</strong>判断的。<span style="color: black;">一般</span><span style="color: black;">来讲</span>,<strong style="color: blue;"><span style="color: black;">仅有</span>新内容才会有时效性,而不是简单地对旧<span style="color: black;">文案</span>、旧资源的转载</strong>。⾼价值资源的判断标准<span style="color: black;">包含</span>:文本<span style="color: black;">拥有</span>可读性,或资源可正常<span style="color: black;">运用</span>。更进一步的<span style="color: black;">需求</span>是,文字内容排版<span style="color: black;">恰当</span>、便于阅读;或<span style="color: black;">宣传</span>少、视频清晰;或资源下载速度快。高价值的资源不仅对搜索引擎友好,更重要的是能带来⽤户体验的<span style="color: black;">提高</span>。<span style="color: black;">区别</span>百度权重会给网站带来的流量预估如下图:</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">除了网站内容和体验的健康外,<strong style="color: blue;">网站结构和页面本身的优化<span style="color: black;">亦</span>是<span style="color: black;">提高</span>PR权重的重要<span style="color: black;">原因</span></strong>。网站结构<span style="color: black;">能够</span>理解成页面和页面之间的层级关系,决定了搜索引擎爬虫<span style="color: black;">是不是</span>能找到对应网页,找到后能否抓取页面内容,以及抓取后能否提取<span style="color: black;">重点</span>信息。行业内<span style="color: black;">通常</span>有<strong style="color: blue;">扁平式和树形式</strong>两种结构。树形<span style="color: black;">指点</span>航层级较多的网站,<span style="color: black;">例如</span><span style="color: black;">外链</span>、网易这种传统门户,它们<span style="color: black;">一般</span>有类似下图<span style="color: black;">这般</span>的层级结构:</p>
<div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://p3-sign.toutiaoimg.com/pgc-image/0b4b0984570742b0b7e2793afa362b80~noop.image?_iz=58558&from=article.pc_detail&lk3s=953192f4&x-expires=1725596492&x-signature=bP9yVZ0sGR9Uqmd04bDg2ythxxY%3D" style="width: 50%; margin-bottom: 20px;"></div>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">树形结构适合大站</strong>,<span style="color: black;">规律</span>清晰,好<span style="color: black;">守护</span>,但索引成本高,爬虫抓取效率相对较低。<strong style="color: blue;">扁平式则是当下<span style="color: black;">非常多</span>网站、博客的主流结构</strong>,<span style="color: black;">一般</span>都<span style="color: black;">仅有</span>2层,以导航+信息流为主,<span style="color: black;">例如</span>36氪。<strong style="color: blue;">扁平式适合小站点</strong>,优点<span style="color: black;">便是</span>对搜索引擎友好,页面权重较高。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">另外</span>,还有<span style="color: black;">有些</span><span style="color: black;">原因</span>会对爬虫不友好,<span style="color: black;">例如</span>页面内嵌FLASH,<span style="color: black;">运用</span>动态URL,所有内容<span style="color: black;">需求</span>登录后<span style="color: black;">才可</span><span style="color: black;">拜访</span>,强制<span style="color: black;">运用</span>Cookies等等,需要<span style="color: black;">大众</span>在设计时<span style="color: black;">重视</span>。<span style="color: black;">意见</span>的优化方向如下图:</p>
