网站优化这两个概念模糊不清，混为一谈。“SEO是狭义的网站优化”才是较为正确的方法。
Website optimization of the two ambiguous concept, be confused. "SEO is the site optimization" in the narrow sense is the method correctly.

“网站优化也叫SEO”的说法其实一直都极具误导性，导致如今上百万的网络中人对网站优化和SEO
"The website optimization is also called SEO" argument is always very misleading, led to hundreds of millions of Internet of website optimization and SEO

SEO是依存于搜索引擎的出现，是网络时代发展的产物；网站优化则偏重于“网站建设”的概念，本质是对网站进行完善，改良，让浏览者满意。网站优化是可以独立于搜索引擎而生存的，它最初不对网络直接负责，更不是以追求搜索引擎排名为终极目标，而是客户满意度，即现在的客户体验。
SEO is dependent on the search engine, is the network time product development; conceptual web site optimization is focused on "site construction", nature is perfect, the site improvement, let visitors satisfaction. Website optimization is independent of the search engine and survival, it initially not directly responsible for the network, but not in the pursuit of search engine ranking as the ultimate goal, but the customer satisfaction, which is now the customer experience.

事实上，没有搜索引擎，就没有SEO；但没有搜索引擎，甚至是没有互联网，网站优化也依然存在。在搜索引擎出现之前，网站优化是完全独立的，它的核心是建设优质的站点，并伴随着互联网的发展和网站自身的拓展而不断加深优化。直至搜索引擎出现后，网站优化才逐渐向搜索引擎的方向发展，并伴随着搜索引擎日渐成为人们浏览互联网信息的重要工具时，网站优化才渐渐成为网站推广乃至网络营销的基础，并直接对SEO负责。因此，与其说SEO是伴随搜索引擎而出现的技术，不如说SEO是由网站优化衍生出来的一门新技术。
In fact, no search engine, no SEO; but no search engine, even without the Internet, website optimization is also still exists. Before the search engine, website optimization is completely independent, which is the core of the construction of high quality site, and accompanied by the expansion of the development of the Internet and the web itself and deepening the optimization. Until the search engine appears, website optimization only gradually to the search engine's development direction, and accompanied by the search engine has become an important tool for people to browse the Internet information, website optimization website promotion and gradually become the basis of network marketing, and directly responsible for SEO. Therefore, it is accompanied by SEO search engine technology appearing, as SEO is a new technology derived from the website optimization.

一个事物的真正面目被越来越多的人所误解所模糊，那么人们还能看到它真正的面目吗? 不能!故SEO需要创新，必须首先要推翻之前的“陈规陋习”，附上时代赋予SEO的独特性征，并在理论上不断趋向完善。
The true face of a thing by more and more people misunderstand the fuzzy, so people can see its true colors? No! So SEO needs to innovate, must overturn "outdated customs and bad habits", with unique characteristics of SEO times, and in theory perfected.

因此，SEO不是网站优化，网站优化更不是SEO！
Therefore, SEO is not the website optimization, website optimization more than SEO!
