什麼是黑帽SEO
國外的論壇行逛的時候，有個老兄問了句：What is blackhat? （什麼是黑帽）
接下來引來了一堆解釋，我們可以來看看國外的SEO們是怎麼看待黑帽的吧
（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，事情就是這麼簡單（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.
對於搜索引擎而言，它是指的一些破壞搜索引擎規律的人的統稱，像一些諸如隱藏鏈接和門頁是原來的黑帽常用手法，現在而言，最好的黑帽技術一般不被大眾站長知道
（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.
黑帽技術其實是調整搜索引擎的規則，一旦被搜索引擎發現，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 bookmarking spam, comment spam, forum spam, domain spam, blog spam, etcetera.
黑帽是：隱藏鏈接，隱藏文本，小文本，白色背景上的白色鏈接，關鍵詞堆砌，錯誤引導的重新定向，鏈接工廠，垃圾郵件群發（還有些專業術語我也不太清楚），還有一些特殊的作弊也屬於它的形式：
電子郵件作弊，搜索引擎作弊，社會書籤作弊，評論作弊，論壇作弊，域名作弊（？），博客作弊等等。
