WordPress 5.3将改变它如何阻止索引

WordPress宣布了一个重要的变化,它将阻止搜索引擎从索引网站。这种变化放弃了传统的Robots.txt解决方案,转而采用机器人元标记方法。此更改符合阻止Google的常见意图。这是为了防止被阻止的网页显示在Google的搜索结果中。

这是WordPress将使用的机器人元标记:

阻止Google从索引编制

长期以来,使用Robots.txt来阻止网站的“索引”是一种标准做法。

“索引”一词意味着GoogleBot会抓取该网站。通过使用Robots.txt阻止功能,您可以阻止Google下载指定的网页,并且假设Google无法在搜索结果中显示您的网页。

但robots.txt指令仅阻止Google抓取该网页。如果Google能够发现该网址,Google仍然可以将其添加到索引中。

因此,为了阻止网站出现在索引中,发布商会阻止Google对网页进行“索引”。这不是一贯有效的。

WordPress 5.3将真正防止索引

WordPress采用了Robots.txt方法。但是版本5.3中的情况正在发生变化。

当发布商目前选择“阻止搜索引擎索引此网站”时,它会向该网站的robots.txt添加一个禁止Google抓取网站的条目。

从WordPress 5.3开始,WordPress将采用更可靠的机器人元标记方法来阻止网站的索引。

此更改将影响“阻止搜索引擎索引此站点”设置。

这种变化是一种改进。 WordPress发布商可以更安全地知道被阻止的网页不会显示在Google的搜索结果中。

WordPress 5.3公告的屏幕截图,文本如下:“在WordPress 5.3中,用于阻止索引的方法将在允许选项”阻止搜索引擎索引此站点“的站点上更改WordPress仪表板中的这些更改。这些更改是作为票证的一部分进行的#43590。这些更改旨在更好地阻止搜索引擎列出网站,而不是仅阻止他们抓取网站。“'width =”600“height =”483“sizes =”(max-width:600px)100vw, 600px“data-srcset =”https://cdn.searchenginejournal.com/wp-content/uploads/2019/09/wordpress-5.3-announcement.png 600w,https://cdn.searchenginejournal.com/wp-content/ uploads / 2019/09 / wordpress-5.3-announcement-480x386.png 480w“data-src =”https://cdn.searchenginejournal.com/wp-content/uploads/2019/09/wordpress-5.3-announcement.png">WordPress 5.3变更公告的屏幕截图。为什么WordPress使用Robots.txt? </p>
<p>WordPress依靠Robots.txt来阻止网站的索引,因为每个人都不会在Google的搜索结果中显示网页。这是标准的做法。</p>
<p>然而,即使每个人都这样做,正如已经解释过的那样,这是一种不可靠的方法。</p>
<p>“索引”一词有两个含义:</p>
<ol>
<li>索引意味着抓取,就像Googlebot访问和下载网页时一样。</li>
<li>索引还可以意味着将网页添加到Google的网页数据库(称为索引)。</li>
</ol>
<p>阻止谷歌“索引”网页将使其无法看到网页,但谷歌仍然可以将网页编入索引并将其添加到谷歌的索引中。合理?</p>
<p> Robots.txt与机器人元标记 </p>
<p>将网页保留在Google索引之外并不是Robots.txt解决方案的目的。这样做是机器人元标记的工作。</p>
<p>因此,很高兴看到WordPress将机器人元标记作为阻止网页在搜索引擎中显示的解决方案。</p>
<p>WordPress 5.3计划于2019年11月发布。</p>
