SEO Tutorial

搜索引擎优化是影响在线可见性的过程。

Search engine optimization is the process of affecting the online visibility of a website or a web page in a web search engine's unpaid results—often referred to as "natural", "organic", or "earned" results. In general, the earlier, and more frequently a website appears in the search results list, the more visitors it will receive from the search engine's users; these visitors can then be converted into customers. SEO may target different kinds of search, including image search, video search, academic search, news search,

and industry-specific vertical search engines. SEO differs from local search engine optimization in that the latter is focused on optimizing a business' online presence so that its web pages will be displayed by search engines when a user enters a local search for its products or services. The former instead is more focused on national or international searches.As an Internet marketing strategy, SEO considers how search engines work, the computer programmed algorithmswhich dictate search engine behavior, what people search for, the actual search terms or keywords typed into search engines, and which search engines are preferred by their targeted audience. Optimizing a website may

involve editing its content, adding content, doing HTML, and associated coding to both increase its relevance

to specific keywords and to remove barriers to the indexing activities of search engines. Promoting a site to

increase the number of backlinks, or inbound links, is another SEO tactic. By May 2015, mobile search had surpassed

desktop search. In 2015, it was reported that Google is developing and promoting mobile search as a key feature

within future products. In response, many brands are beginning to take a different approach to their Internet

marketing strategies.
