Unblocking resources with Webmaster Tools

網站管理員通常會在網頁中使用連結圖片、CSS 和 JavaScript 檔案，讓網頁不但美觀，更具備豐富的實用功能。但如果這些資源遭到封鎖，無法由搜尋引擎進行檢索，Googlebot 在轉譯這些網頁以供搜尋時，就無法使用這些資源。Google 網站管理員工具現在可提供
「封鎖的資源」報告
，協助您找出並解決這類問題。
這份報告會先列出一份主機清單，指出您的網站目前使用的遭封鎖資源 (例如 JavaScript、CSS 和圖片) 是由哪些主機所提供。點選各列即可查看遭到封鎖的資源詳細清單以及嵌入這些資源的網頁。這份報告隨後會導引您逐步診斷並解決問題，讓我們得以檢索網頁內容並建立索引。
擷取並轉譯
的更新內容也說明了這些遭封鎖資源的重要性。現在當您要求截取並轉譯網址時，會顯示以 Googlebot 角度和一般使用者角度所轉譯的螢幕擷取畫面。如此一來，您就可以更容易發現問題癥結，找出 Googlebot 看到的網頁內容有所差異的原因。
網站管理員工具僅會顯示您可能能夠處理的主機，因此目前我們不會顯示各個不同網站 (例如熱門的分析服務) 所使用的主機。由於要更新所有 robots.txt 檔案相當耗時 (原因通常不是技術問題！)，建議您先從受到封鎖時會造成重大視覺效果差異的資源著手。如要進一步瞭解相關步驟，請參閱我們的

If these resources are blocked from crawling, then Googlebot can't use them when it\nrenders those pages for Search. Google Webmaster Tools now includes a\n[Blocked Resources Report](https://support.google.com/webmasters/answer/6153277)\nto help you find and resolve these kinds of issues.\n\n\nThis report starts with the names of the hosts from which your site is using blocked resources\nsuch as JavaScript, CSS, and images. Clicking on the rows gives you the list of blocked resources\nand then the pages that embed them, guiding you through the steps to diagnose and resolve how\nwe're able to crawl and index the page's content.\n\n\nAn update to\n[Fetch and Render](https://support.google.com/webmasters/answer/6066467)\nshows how these blocked resources matter. When you request a URL be fetched and rendered, it now\nshows screenshots rendered both as Googlebot and as a typical user. This makes it easier to\nrecognize the issues that significantly influence why your pages are seen differently by\nGooglebot.\n\n\nWebmaster Tools attempts to show you only the hosts that you might have influence over, so at the\nmoment, we won't show hosts that are used by many different sites (such as popular analytics\nservices). Because it can be time-consuming (usually not for technical reasons!) to update all\nrobots.txt files, we recommend starting with the resources that make the most important visual\ndifference when blocked. Our\n[Help Center article](https://support.google.com/webmasters/answer/6153277)\nhas more information on the steps involved.\n\n\nWe hope this new feature makes it easier for you to spot and then unblock resources used by your\nwebsite! Should you have any questions, you can drop by our\n[webmaster help forums](https://support.google.com/webmasters/go/community).\n\n\nPosted by\n[John Mueller](https://twitter.com/johnmu?rel=arthur), Webmaster\nTrends Analyst, Google Switzerland"]]
