<h1 style="color: black; text-align: left; margin-bottom: 10px;">PR劫持,购买外链时最怕遇到的骗局,<span style="color: black;">咱们</span>应该<span style="color: black;">怎样</span>去规避呢?</h1>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">众所周知,一个网站的权重<span style="color: black;">针对</span>网站排名的影响是非常大的,<span style="color: black;">因此</span>基本上<span style="color: black;">每一个</span>网站优化者都会去寻找<span style="color: black;">有些</span><span style="color: black;">优秀</span>的外链来<span style="color: black;">加强</span>自己网站的权重,虽然百度多次声明<span style="color: black;">再也不</span>看重外链,但这些搜索引擎<span style="color: black;">机构</span>发出来的说辞,<span style="color: black;">咱们</span>应该相信吗?据笔者几个月来的经验判定,百度依然非常注重外链,并且,<span style="color: black;">针对</span>网站权重,任何搜索引擎大概<span style="color: black;">日前</span>还<span style="color: black;">无</span>找到比外链更加<span style="color: black;">靠谱</span>的证明办法。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">为了节省时间,<span style="color: black;">非常多</span>外链获取者采取直接购买<span style="color: black;">优秀</span>外链的方式来<span style="color: black;">加强</span>网站权重,<span style="color: black;">所说</span>的<span style="color: black;">优秀</span>外链<span style="color: black;">便是</span>与自己的网站<span style="color: black;">关联</span>性高并且权重高的网站,PR值是公认最<span style="color: black;">靠谱</span>的网站权重表现,<span style="color: black;">因此</span>,<span style="color: black;">咱们</span>在寻找外链时非常看重网站的PR值,但PR值<span style="color: black;">亦</span>有假的,你<span style="color: black;">晓得</span>吗?这<span style="color: black;">便是</span>PR劫持技术。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">咱们</span>在讨论这个问题时,以google为例子讲PR劫持,至于其它搜索引擎权重,道理上是一模<span style="color: black;">同样</span>的。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">PR劫持</strong>(PR Hijacking),<span style="color: black;">运用</span><span style="color: black;">诈骗</span>手段<span style="color: black;">得到</span>工具条上比较高的PR值<span style="color: black;">表示</span>.<span style="color: black;">办法</span>是利用<span style="color: black;">转</span>,<span style="color: black;">通常</span>搜索引擎在处理301和302 转向时,是把<span style="color: black;">目的</span>URL当做实际应该收录的 URL. 当然<span style="color: black;">亦</span>有特例,<span style="color: black;">不外</span>在大部分<span style="color: black;">状况</span>下是<span style="color: black;">这般</span>处理的。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">因此</span><span style="color: black;">倘若</span>作<span style="color: black;">坏处</span>者从域名A做301或302<span style="color: black;">转</span>到城名B,而域名B的PR值比较高,域名A在PR值更新后,就会<span style="color: black;">表示</span>域名B的PR值.有人就利用这一点,把自己的域名PR值刻意<span style="color: black;">加强</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">最简单的<span style="color: black;">便是</span>域名A先做301或302<span style="color: black;">转</span>到高PR的域名B,等工具条PR值更新过后,立刻取消转向,放上自己的内容。用户<span style="color: black;">拜访</span>这个网站A,看到的是一个高PR值,却不<span style="color: black;">晓得</span>PR值是<span style="color: black;">经过</span>转向劫持得到的,不是这个网站的真实PR值,而是<span style="color: black;">另一</span>一个网站的。劫持的PR<span style="color: black;">表示</span>值<span style="color: black;">最少</span>维持到下一次工具条PR更新,<span style="color: black;">通常</span>有两三个月时间!有些<span style="color: black;">违法</span>的外链售卖者就会利用这种办法,将自己的网站的PR值<span style="color: black;">短期</span>内变得很高而进行出售牟利。</p>

</div>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">更隐晦一点的办法是,<span style="color: black;">经过</span>程序检测到Google蜘蛛,返回301或302转向,对聋通<span style="color: black;">拜访</span>者和其他蜘蛛都返回正常内容。<span style="color: black;">这般</span>,用户看到的是普通网站,<span style="color: black;">仅有</span>Google 会看到转向.</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">PR劫持的作<span style="color: black;">坏处</span>者的目的<span style="color: black;">亦</span>很<span style="color: black;">显著</span>,<span style="color: black;">便是</span>为了卖链接,<span style="color: black;">倘若</span><span style="color: black;">重点</span>诉求或<span style="color: black;">独一</span>诉求<span style="color: black;">便是</span>高PR值,这无疑<span style="color: black;">便是</span><span style="color: black;">诈骗</span>,这种网站上的链接对购买者的网站PR值<span style="color: black;">无</span>任何贡献。在寻找和买链接的时候,<span style="color: black;">倘若</span>对方炫耀的<span style="color: black;">便是</span>高PR值,都要非常小心。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">怎么样</span>鉴别<strong style="color: blue;">PR劫持</strong>呢?最简单的方式 <span style="color: black;">便是</span>查看此网站的收录<span style="color: black;">状况</span>,一个高PR值的网站不可能只收录少量的网页,<span style="color: black;">倘若</span><span style="color: black;">咱们</span>看到一个网站PR值很高,但收录量<span style="color: black;">仅有</span>几条几十条,<span style="color: black;">那样</span>,它的PR值是劫持来的无疑,这种外链<span style="color: black;">导致</span>不要购买。第二种方式<span style="color: black;">便是</span>看Google的网页快照,<span style="color: black;">倘若</span>你看到的网页是一个样,Google快照<span style="color: black;">表示</span>的却是<span style="color: black;">另一</span>一个样子,网站标题和logo都是另一个网站,这很可能<span style="color: black;">便是</span>PR劫持了.</p>
