I estimate that to do web design and SEO to the study of science and engineering in the majority, but the real search engine optimization requested by the more liberal arts foundation, such as marketing, advertising, psychology, writing, and so on.    Of course, it also requires some technical basis, such as HTML, PHP, server infrastructure and knowledge.    However, the technical content of these requirements is not high.    Procedures for the preparation of a senior member does not mean to become a good search engine optimization staff. 

  Search engine optimization tools used Jizhi.    On a web site you need to make an overall consideration and planning.    Different marketing techniques, different SEO practices, in order to obtain a balanced.    There should not be any one of the factors is very prominent, or very weak. 

  Of course, these two aspects are and easy to say, difficult to do. 

  Many people feel that SEO is very simple, after reading some of the information into the experts.    In fact some minor local needs you accumulated a lot of experience, and search engine and search engine optimization have a profound understanding. 

  Take a natural search engine optimization of examples.    We all know that the Web site to log into the website classification directory access reverse link is a good way.    Although the importance of reverse link now controversial, but undeniable quality Categories reverse link has a certain impact on the ranking. 

  Many station will be completed in the web site design, he knew all the important categories to submit, which is also recommended by many experts.    However, in practical work, I was not recommended at the same time submit to those directories. 

  Search engine from the point of view of a web site if a sudden in one day or a certain time, in the all-important site in a directory, you think this natural?    Obviously, the only think of the minds of the people will do SEO.    General businessmen will think about this?    The vast majority would not. 

  Of course, do not say that you will definitely lead to problems.    But if this SEO marks too much, on the problem.    You need a little from each of the local attention. 

  As another example of the balance.    Generally speaking, the best is to optimize your site in many Key words rankings enhance, and not only a particular concern you the most words into the first, but other less popular keywords and other related Web are the very back row.    In other words, you should not have an All-Star website (it is generally Home) in the industry's most popular search you when Keywords ranked first, and other related keywords can not find your site. 

  This also applies to PageRank, some high PR site's home page, but inside the content of the whole page PR is zero.    Or a part of the website PR good, but most bad. 

  You should link through the appropriate internal structure, so that all your web PR has been raised so that you can page PR uniform distributed to individual pages.    There are several pages that you would like to focus on, but this should not be allowed to several important Web pages and other minor disparity too.
