在海外的論壇行逛的時刻，有個老兄問了句：What is blackhat? （啥子是黑帽）

接下來引來了一堆詮釋，我們可以來看看海外的SEO們是怎麼對待黑帽的吧

（1）Think in terms of American cowboys.
The good guys wear white hats.

The bad guys wear black hats.

Whitehat good; blackhat bad. Simple as that.

There is also greyhat/grayhat which means that it’s in a grey area between the two.

想想看一群美國牛仔吧，好男孩就帶白帽，壞男孩就帶黑帽，白帽好，黑帽壞，事物就是這樣簡單（幽默。。。）

（2）In relation to SEO, it refers to those who use techniques which are underhand or break the rules of search engines. Things like hidden links and doorway pages are blackhat techniques which were used in the past. In general, the best blackhat techniques are not often made public.

對於搜索引擎網站而言，它是指的一點毀傷搜索引擎網站規律的人的統稱，像一點諸如掩飾鏈接和門頁是原來的黑帽常用手法，如今而言，最好的黑帽技術普通不被大眾站長曉得

（3）Blackhat refers to SEO techniques that go against search engine guidelines. Using blackhat techniques can get your site banned if the search engines catch up with you.

黑帽技術實際上是調試搜索引擎網站的規則，一朝被搜索引擎網站發覺，你的站會被ban

(4)Black hat is…
hidden links, hidden text, tiny text, white on white links, keyword stuffing, cloaking, misleading redirects, arbitrage, scraping, synonymizing, doorway pages, link farms, browser hijacking, hot-linking, email harvesting, and especially SPAM in all its forms:
email spam, search engine spam, social book馬克ing spam, comment spam, forum spam, domain spam, blog spam, etcetera.

黑帽是：掩飾鏈接，掩飾文本，小文本，白的顏色環境上的白的顏色鏈接，網站關鍵詞堆砌，不正確指導的從新定向，鏈接工廠，垃圾郵件群發（還有點專業專門用語我也不太明白），還有一點特別的作弊也歸屬它的方式：

電子郵件作弊，搜索引擎網站作弊，社會形態書簽作弊，述評作弊，論壇作弊，域名作弊（？），博客作弊等等

以上是幾個商議比較典型性的，我挑出來供大家看看，呵呵，期望能對大家有一絲幫忙
