谷歌机器人 rel=“nofollow”停止关注多久

发布于 2024-09-16 14:25:42 字数 113 浏览 6 评论 0原文

我刚刚在一些链接中添加了 rel="nofollow" 。

有人知道在链接中添加“nofollow”后谷歌需要多长时间才能停止关注吗? 我一小时前添加,但仍然看到他们爬行“nofollow”链接。

I just added rel="nofollow" to some links.

Anyone know how long it takes for google to stop following after "nofollow" is added to a link?
I added an hour ago and still see them crawling the "nofollow" links.

它可能不会停止关注您的 rel="nofollow" 链接。 根据维基百科

Google 表示,他们的引擎按字面意思理解“nofollow”,根本不“跟随”该链接。然而,SEO 进行的实验显示出相互矛盾的结果。这些研究表明,Google 确实会跟踪该链接,但不会将链接到的页面编入索引,除非该页面已因其他原因(例如指向该页面的其他非 nofollow 链接)而位于 Google 的索引中。

It might be the case that it won't stop following your rel="nofollow" links. According to Wikipedia:

Google states that their engine takes "nofollow" literally and does not "follow" the link at all. However, experiments conducted by SEOs show conflicting results. These studies reveal that Google does follow the link, but does not index the linked-to page, unless it was in Google's index already for other reasons (such as other, non-nofollow links that point to the page).

使用 Google 网站站长工具,您可以查看上次抓取您的网站的时间网站,如果链接仍然显示在搜索中,则根据 @Bears 帖子,它们可能存在冲突。

From Google's Webmaster Central:

Google's spiders regularly crawl the
web to rebuild our index. Crawls are
based on many factors such as
PageRank, links to a page, and
crawling constraints such as the
number of parameters in a URL. Any
number of factors can affect the crawl
frequency of individual sites.

Our crawl process is algorithmic;
computer programs determine which
sites to crawl, how often, and how
many pages to fetch from each site. We
don't accept payment to crawl a site
more frequently. For tips on
maintaining a crawler-friendly
website, please visit our webmaster

Using Google Webmaster Tools, you can see the last time it crawled your website and if the links are still showing in the searches, they may be conflicting as per @Bears post.

这取决于很多事情。 Google 的数据库分布广泛,因此更改可能需要一段时间才能传播。此外,爬虫可能需要一些时间才能重新访问您添加了 nofollows 的页面 - 同样,这是由某些封闭的 Google 算法计算的。在最坏的情况下,我已经看到数十天没有更新索引;最好的情况是几分钟。方式将是几天。要有耐心,年轻的绝地武士;)

That depends on many things. Google's databases are massively distributed, so it may take a while for the change to propagate. Also, it may take the crawler some time to revisit the page where you added the nofollows - again, this is computed by some closed Google algorithm. In the worst cases, I've seen tens of days without the indexes getting updated; best case, few minutes. The modus would be a few days. Be patient, young Jedi ;)

我正在跟踪大约 7000 个页面,了解谷歌如何访问它们。是的,即使我放置了 nofollow ,它也会继续关注页面,但会持续一段时间。在最终删除同一页面之前,它会抓取同一页面几次。所以这需要时间。

I am keeping track of around 7000 pages on how google visits them. Yes it keeps following the pages even if I put the nofollow thing but for a while. It will crawl the same page a couple of times before it finally removes it. So it'll take time.
