谈了这么多SEO，有可能让人误解搜索引擎优化在网站运营中占很大一部分，其实搜索引擎优化只是网站运营食物链中比较低层的一个位置。

So much talk about SEO, a search engine optimization may be misleading on the website represent a large part of the operation, in fact, search engine optimization web site operators in the food chain is a relatively low-level position.

我觉得从总体上来说，网站运营和SEO是这样层层包括的关系：

网站运营－网络营销－网站推广－SEM－SEO

网站运营是一个总体概念，包括了设计，编程，客户服务，公司管理等。网络营销是网站运营的一部分。

I think that overall, the site operator and SEO is the relationship between such layers include:
Web site operators - Internet Marketing - Website Promotion-SEM-SEO
Web site operator is a general concept, including design, programming, customer service, the company management. Network marketing is a part of site operations.

网络营销又包含很多内容，并不局限于网站本身的推广。网络营销还包含比如blog营销，市场定位，价格策略，销售流程的设计和优化，产品策略，电子邮件营销等。网站推广是网络营销的一部分，

网站推广又包括很多方法，比如联署计划，论坛的参与，免费礼物以吸引用户，发布新闻稿等。SEM（搜索引擎营销）是网站推广的其中一种手段。

SEM主要包括SEO（搜索引擎优化）和PPC竞价广告。

SEO只是网站推广和网络营销的一小部分内容，当然我个人觉得SEO是网站推广最有效的手法。

专门招聘SEO人员的公司和网站似乎不是很多，所以做SEO的人应该把自己的知识往食物链的上层扩展，多了解网站推广和网络营销的总体知识，对职业的发展有好处，而且对SEO本身的深度和广度也有很大好处。有很多SEO技巧不能只从技术层面看，而要考虑到这些技术对网站整体营销的影响。

Internet marketing also contains many elements, not limited to the promotion of the site itself. Internet marketing also includes such as blog marketing, market positioning, pricing strategies, sales process design and optimization, product strategy, e-mail marketing. Website promotion is part of network marketing,
Website promotion also includes many methods such as joint programs, forums, free gifts to attract customers, press releases and so on. SEM (search engine marketing) is a website to promote one of the means.
SEM includes SEO (search engine optimization) and PPC advertising auction.
SEO is website promotion and internet marketing a small part, of course, I personally think that SEO is a web site to promote the most effective way.
Recruitment of staff specialized SEO company and website does not seem a lot, so people should be doing SEO for their own knowledge to the food chain and expand and learn more about website promotion and internet marketing in general knowledge, professional development is good, but SEO Ben Shen The depth and breadth of great benefit. There are many SEO techniques not only from a technical level, these technologies have to take into account the overall marketing of the site.
