甚麽是SEO marketing?

SEO = search engine optimization

搜尋引擎最佳化(Search Engine Optimization，簡稱SEO)是一種利用搜索引擎的搜索規則來提高目的網站在有關搜索引擎內的提名的方式。由於不少研究發現，搜索引擎的用戶往往只會留意搜索結果最開首的幾項條目，所以不少商業網站都希望透過各種形式來干擾搜索引擊的排序。當中尤以各種依靠廣告維生的網站為甚。

所謂“針對搜尋引擎作最佳化的處理”， 是指為了要讓網站更容易被搜尋引擎接受。 搜尋引擎會將網站彼此間的內容做一些相關性的資料比對。 然後再由瀏覽器將這些內容以最快速且接近最完整的方式，呈現給搜尋者。

搜索引擎优化对于任何一家网站来说，要想在网站推广中取得成功，搜索引擎优化都是至为关键的一项任务。同时，随着搜索引擎不断变换它们的排名算法规则，每次算法上的改变都会让一些排名很好的网站在一夜之间名落孙山，而失去排名的直接后果就是失去了网站固有的可观访问量。所以每次搜索引擎算法的改变都会在网站之中引起不小的骚动和焦虑。我们可以说，搜索引擎优化也成了一个愈来愈复杂的任务。


Search engine optimization (SEO), a subset of search engine marketing, is the process of improving the volume and quality of traffic to a web site from search engines via "natural" ("organic" or "algorithmic") search results. SEO can also target specialized searches such as image search, local search, and industry-specific vertical search engines.


A typical Search Engine Results Page (SERP)As a marketing strategy, SEO considers how search algorithms work and what people search for in order to increase a site's relevancy. SEO efforts may involve a site's coding, presentation, and structure, as well as fixing problems that could prevent search engine indexing programs from fully spidering a site. Other, more noticeable efforts may include adding unique content to a site, and making sure that the content is easily indexed by search engines and also appeals to human visitors.

The term SEO can also refer to "search engine optimizers," a term adopted by an industry of consultants who carry out optimization projects on behalf of clients, and by employees who perform SEO services in-house. Search engine optimizers may offer SEO as a stand-alone service or as a part of a broader marketing campaign. Because effective SEO depends upon the source code of a site, SEO tactics may be incorporated into web site development and design. The term "search engine friendly" describes designs, menus, content management systems and shopping carts that are easy to optimize.
