Changes in crawl error reporting for redirects

我们发现,在
网站站长工具
中,重定向网页
抓取错误
的显示方式有时会让网站站长颇感困惑。现在是时候改进这种方式来使相关错误数据更清晰、更易于诊断问题了!尽管以前我们都是针对初始网址(重定向网址)报告错误,但从现在起,我们将改为针对最终网址(实际返回错误代码的网址)显示错误。
网址A重定向到网址B,然后网址B返回了错误。请忽略此处的重定向类型和错误类型,我们只是举例而已。
这一变动可能还会体现在部分网站的错误总数中。例如,当您的网站移至新网址时,您将只会看到新网址返回的抓取错误(假定旧网址可以正确地重定向),这就可能导致这些网站的错误总数发生明显变化。
请注意:这一变动仅会影响这类抓取错误在网站站长工具中的显示方式。此外,我们还想提醒您,如果应返回错误(例如:网址不存在)的网址发生抓取错误,那么系统显示抓取错误
并不会对该网站其他部分的编入索引和排名产生任何不利影响
(另请参阅
Google+上的相关讨论
)。
我们希望这一改动可让您更轻松地跟踪抓取错误,并清除您从未察觉到的意外错误!如有任何疑问,您可以随时在此发布问题;也可以通过访问

Previously, errors were reported on the original redirecting URL. Now, errors are reported on the final URL that actually returns the error code. This change, effective from January 22, 2014, aims to simplify error diagnosis. While total error counts may fluctuate, the change only affects display, not website indexing or ranking. External tools like cURL can be used to verify errors on the final URL.\n"],null,["# Changes in crawl error reporting for redirects\n\nWednesday, January 22, 2014\n\n\nIn the past, we have seen occasional confusion by webmasters regarding how\n[crawl errors](https://support.google.com/webmasters/answer/35120)\non redirecting pages were shown in\n[Webmaster Tools](https://search.google.com/search-console).\nIt's time to make this a bit clearer and easier to diagnose! While it used to be that we would\nreport the error on the original---redirecting---URL, we'll now show the error on the\nfinal URL---the one that actually returns the error code.\n\nLet's look at an example:\n\n\nURL A redirects to URL B, which in turn returns an error. The type of redirect, and type of error\nis unimportant here.\n\n\nIn the past, we would have reported the error observed at the end under URL A. Now, we'll instead\nreport it as URL B. This makes it much easier to diagnose the crawl errors as they're shown in\nWebmaster Tools. Using tools like\n[cURL](https://www.google.com/search?q=curl) or your favorite\n[online server header checker](https://www.google.com/search?q=http+header+viewer),\nyou can now easily confirm that this error is actually taking place on URL B.\n\n\nThis change may also be visible in the total error counts for some websites. For example, if your\nsite is moving to a new domain, you'll only see these errors for the new domain (assuming the old\ndomain redirects correctly), which might result in noticeable changes in the total error counts\nfor those sites.\n\n\nNote that this change only affects how these crawl errors are shown in Webmaster Tools. Also,\nremember that having crawl errors for URLs that should be returning errors (for example, they\ndon't exist)\n[does not negatively affect the rest of the website's indexing or ranking](/search/blog/2011/05/do-404s-hurt-my-site)\n(also as [discussed on Google+](https://plus.google.com/+JohnMueller/posts/RMjFPCSs5fm)).\n\n\nWe hope this change makes it a bit easier to track down crawl errors, and to clean up the\naccidental ones that you weren't aware of!
