Hyphen and Underscore for SEO Redux字號，並強調對搜索引擎優化Redux

This is an important update to a post that appeared on September 12, 2007.這是一個重要的更新後出現在9月12日， 2007年。

It seems that Google still doesn’t like underscores, as the big G’s spam czar Matt Cutts said in a post on his blog:看來，谷歌仍然沒有想強調，作為大G的垃圾郵件沙皇馬特卡茨說，在後在他的博客：

People thought that underscores are the same as dashes to Google now, and I didn’t quite say that in the talk. 人們認為，底線是一樣的破折號，以谷歌現在，我並沒有完全說，在交談。 I said that we had someone looking at that now. 我說，我們已有人看，現在。 So I wouldn’t consider it a completely done deal at this point. 所以，我不會認為這是一種完全木已成舟在這一點上。 But note that I also said if you’d already made your site with underscores, it probably wasn’t worth trying to migrate all your urls over to dashes. 但是注意，我也說，如果您想您已經取得了突出的網站，它可能是不值得嘗試遷移所有的網址給破折號。 If you’re starting fresh, I’d still pick dashes. 如果你已經開始新鮮，我還是選擇破折號。

I write a regular column for a major publisher.我寫常柱的一個主要出版商。 The system utilizes a fantastic CMS (content management system) but one thing about it that has always bugged me since I was first shown the ins and outs is that image and other filenames have to have underscores rather than hyphens.該系統採用了美妙不育系（內容管理系統） ，但有一件事它一直竊聽我，因為我是第一次表明，里里外外的是，圖像和其他文件名必須有底線，而不是連字號。 Eg file_name.jpg not file-name.jpg.如不file_name.jpg文件name.jpg 。 Of course, I always use a descriptive tag with the file_name but that doesn’t help in terms of SEO if the file_name itself is rendered as a single nonsensical entity in Google’s eyes, rather than being separated into two meaningful words and hence a useful keyphrase - file-name - by the hyphen.當然，我總是使用一個描述標記的文件名，但無助於從搜索引擎優化，如果文件名本身就是提供作為一個單一的荒謬實體谷歌的眼睛，而不是分成有意義的詞，並因此有用keyphrase -文件名-由連字號。

What would be ideal would be if Matt were to tell us that the Google algorithm now treats the _underscore_ as a word separator equivalent to the -hyphen-, but unfortunately, it seems, it does not.什麼是理想的，如果將馬特是告訴我們，現在谷歌算法對待_underscore_作為一個詞分離相當於，字號， ，但不幸的是，似乎沒有。 This means that all those file_names will be seen as file-names or more explicitly “file names” and will not gain the relevance of that keyphrase, which is still lost on Google.這意味著所有這些file_names將被視為文件名稱或更明確地“檔案名稱” ，並不會得到相關的keyphrase ，它仍然失去了對谷歌。 This is bad news for the Sciencebase site, which has a lot of legacy pages that used underscores in the html page names.這是個壞消息的Sciencebase的網站，其中有很多傳統的網頁上突出使用在HTML的網頁名稱。

Nevertheless, in that same talk, Matt recommended various optimization techniques for Wordpress bloggers (which apply equally to every website, to be frank):然而，在相同的交談，就提出了各種優化技術的WordPress的博客（這同樣適用於每一個網站，坦率地） ：

He recommended using a plugin or hack that swaps the name of the blog title with the name of the individual post title, this has always been the case for Sciencetext.他建議用插件或黑客工具，用來換名稱的博客標題的個人姓名，職稱，這一直是如此Sciencetext 。

He said everyone should use the “Alt” attribute while blogging and with photos.他說，每個人都應該使用“備選”屬性，而博客和照片。 This is important not only for SEO but for vision-compromised readers.這一點是重要的不僅是搜索引擎優化，但對視覺的影響讀者。

Interestingly, Google does not care about the number of slashes in a URL (blog/title/date/#), so bloggers needn’t worry about the permalinks and sub-folders unless they’re concerned with Yahoo ranking, apparently Yahoo still does care about slashes.有趣的是，谷歌並不關心一些斜線的網址（博客/標題/日期/ ＃ ） ，所以博客不必擔心的永久性和子文件夾，除非他們擔心雅虎排名，顯然還沒有雅虎關心斜線。

Another interesting point that emerged is that Google essentially ignores file extensions in a URL in terms of ranking (.php, .html, .htm, .asp, .aspx, .jsp are all seen as equivalent. But, don’t use .exe, that’sa special case and dangerous for SEO.另一個有趣的一點，出現的是，谷歌基本上忽略文件擴展名的網址中的排名（ 。 PHP中， 。 html文件， 。熱媒， 。動態。如需， 。 JSP的都被視為等同。但是，請不要使用。程序，這是一個特殊情況和危險的搜索引擎優化。

One final point, if you are hoping to get your blog into Google News you must have multiple authors, but everyone knows that don’t they?最後一點，如果你希望得到您的博客到谷歌新聞您必須擁有多個作者，但大家都知道，這樣做不是嗎？
