《速贝SEO实战培训》吧，不用找其它教程了，覆盖面很强，在优化思想，优化方法，优化策略，优化工具，优化案例等多方面都讲得非常细，值得一学！我现在已经在通过速贝SEO策略实施优化了，虽然刚开始不久，但是已经有所成效！

以下内容来自于百度百科seo的内容全称：Search Engine Optimization，即搜索引擎优化，为了说明什么是网站对搜索引擎优化，站长不妨看看对搜索引擎不优化的网站有哪些特征：1、网页中大量采用图片或者Flash等富媒体(Rich Media)形式，没有可以检索的文本信息，而SEO-Answer最基本的就是文章SEO和图片SEO;2、网页没有标题，或者标题中没有包含有效的关键词;3、网页正文中有效关键词比较少(最好自然而重点分布，不需要特别的堆砌关键词);4、网站导航系统让搜索引擎“看不懂”;5、大量动态网页影响搜索引擎检索;6、没有被其他已经被搜索引擎收录的网站提供的链接;7、网站中充斥大量欺骗搜索引擎的垃圾信息，如“过渡页”、“桥页”、颜色与背景色相同的文字;8、网站中缺少原创的内容，完全照搬硬抄别人的内容等。关于SEO-Answer严谨的定义如下：SEO-Answer是指在了解搜索引擎自然排名机制的基础上，对网站进行内部及外部的调整优化，改进网站在搜索引擎中关键词的自然排名，获得更多流量，吸引更多目标客户，从而达到网络营销及品牌建设的目标。搜索引擎检索原则是不断更改的，检索原则的更改会直接导致网站关键字在搜索引擎上排名的变化，所以搜索引擎优化并非一劳永逸。在意识层面站长对SEO可以形象理解为: 当用户进入搜索引擎，就好像进入了一个偌大的图书馆。那么在这个图书馆里面有非常多的分类,分类分成大分类(可以理解为书架)小分类(可以理解为书架上面的格子)以及具体到最小的分类(书的内容)——长尾关键词。在图书馆里面每天都在增加新的内容，那么一个新的网站出现就等于一个分类里面的一本新书出现。那么书里面的书名以及顺序就相对应到网站的TITLE以及Description。可是如果“别人”(可以指搜索引擎)进入图书馆去泡馆的时候发现这本书，虽然是这个分类或者一个系列里的书，但是这本书的书名跟之前的一些书的书名完全一样，那么肯定会让读者误会站长们是在抄袭别人的书，所以原创将影响到站长们的排名。那么虽然站长们的网站是新的，但是其实在刚开始站长们就不可能有一个好的排名了。这严重影响到日后的优化。网站优化()能够帮助站长们提高网页的综合指数，如果站长们的链接已经得到提升，继续保持高质量反向链接数的增加和内容的维护，站长们的左侧排名会继续保持或提高。除非后期应用了作弊的方式而受到惩罚或停止后期的维护。而竞价广告如果停止了，网站链接也就会即刻消失。超过95%的搜索引擎使用者会优先考虑搜索引擎给出的常规结果，这其中绝大部分人只有在左侧无法得到满意结果时才会去浏览右侧的广告。
