SEO Is the abbreviation of search engine optimization in English, which means search engine optimization in Chinese. The main work is to optimize the web pages by understanding how various search engines crawl Internet pages, index them, and determine their ranking of search results for a specific keyword, so that the whole web page is friendly to search engines, thus improving the natural ranking of search results for target keywords, allowing potential users to find themselves, and thereby improving Website production Visits. Usually, users' usage habits only click on the search results on the first few pages. Relevant research shows that the difference between the top 3 pages and the top 4-10 pages is about 100 times.
1. Implementation of SEO plan 1.1 Theoretical analysis When a user searches for information by keywords through a search engine, the search engine will search in the database. If it finds a website that meets the user's requirements, it will use a special algorithm - usually calculate the relevance and ranking of each page according to the matching degree of keywords in the page, the location/frequency of occurrence, link quality, etc, In order The order returns these web page links to the user. The search engine includes four parts: web crawler, index module, information retrieval and user interface. The web crawler function can determine which pages the search engine will crawl first, or only crawl which pages, and not crawl which pages. Link analysis is the core of a crawler. PageRank algorithm is a famous link analysis algorithm. The algorithm formula is as follows: PR（i）＝（1－d）＋d Σ j［PR（j） ／ N（j）］（1） Where i and j refer to web pages, and PR refers to the importance of web pages. The value range is 0-10. The more important a web page is, the higher its PR value is. Function N refers to the number of exported links of the web page, j refers to the web page linked to i, and d refers to the damping coefficient, which is usually 0.85. Obviously, web page keywords are closely related to web page authority, and the export links, internal link structure, and site topology of web pages will also have an impact on ranking.
1.2 Specific implementation steps Specifically, when implementing website optimization, it can be carried out through website static transformation, keyword optimization, link construction, content development, website map and other methods:
1.2.1 Static transformation The website built with dynamic technology is easy to maintain and update information throughout the site, but it is not conducive to search engine inclusion. When optimizing, you need to use dynamic server technology to generate static HTML. Static websites reside in memory. On the one hand, it can reduce the burden of their servers, especially database servers. On the other hand, because they generate HTML static pages, static pages are highly friendly to search engines, which are easy to be retrieved by crawlers, and their websites are more likely to be searched by search engines.
1.2.2 Keyword optimization Key words need to be mentioned frequently in articles. Keyword technical analysis and selection is one of the most important tasks of SEO. Search engines search based on keywords, and keyword optimization is mainly reflected in the density and distribution of keywords [3]. First, determine the core keywords of the website, and then generate key phrases or short sentences around the core keywords. The places where keywords are placed in a webpage include Title, Meta tag, webpage body, ALT tag, etc. The keyword density should preferably be between 2% and 8%. For example, the code for placing keywords on the homepage of Jiaozuo University website is: <title>Welcome to Jiaozuo University - Jiaozuo University</title> <meta name="keywords" content="Jiaozuo University Enrollment Specialist"> <meta name="description" content="Jiaozuo University"> It can be seen that the density of the keywords "university" and "Jiaozuo" is relatively high. Therefore, when searching for "university" in Google, Jiaozuo University's website has achieved a good ranking (the data on December 8, 2009 was in the top ten). During optimization, keywords, __description and title tags should be added to each static page, and ALT attribute should be added to all image tags to increase the density of keywords and balance the distribution of keywords.
1.2.3 Link construction Link is an important element of the Internet and a link between web pages. It organically combines information scattered in various physical regions, so that people can travel on the Internet conveniently and freely to obtain the information they need. All web pages are linked together through links to form a crisscross and complex network, that is, the Internet. Link optimization is mainly to increase the quantity and quality of imported links Quantity. Import links are the most important factors affecting search engine ranking besides page titles and topics. The links that can most improve the ranking are home page links from websites with high PR values, and links from authoritative pages in the theme community [4]. In addition, externally connected descriptive text plays a very important role. This text should be related to the target page title keyword and topic keyword. The code for adding a link is:<a href="link URL" title="link title">link text</a>. Through the continuous scoring of the above internal and external links, with the gradual enrichment of the website content, the overall weight of the website will show a healthy upward trend, and gradually enhance the "status" of the website in the Internet.
1.2.4 Content customization The appropriateness of content customization will also affect the ranking of the website. You can skillfully add keywords to the page. For example, add keywords in the company profile. The added keywords can be blacked and skewed in format, or add some hyperlinks appropriately. This can be better retrieved by search engines. However, it should be noted that too many keywords should not be added, otherwise it may cause bad effects and reduce the system's evaluation of the website.
1.2.5 Establish and submit website map Site maps have many advantages. With the help of site maps, search engines can see the internal structure of website construction more clearly. Once the website has any changes, the site map will notify the search engine at the first time. These updated pages will be included faster than those without a site map [5].
1.2.6 Strengthen the daily management and monitoring of the website After the completion of website construction and basic optimization, the most important thing is the daily management and traffic monitoring of the website, and do a good job in anti-virus and anti attack. Submit websites to major search engines and open classified directories, add traffic statistics codes to the websites, and check and analyze the visits and visit details every day. When a search engine ranks websites, it not only depends on the information relevance of the web page, but also considers how high the click rate of the website and how many external links there are [6]. Therefore, keeping the information of the website updated in time, enriching the content of the website, and strengthening the content construction of the website become the core work in website maintenance. A high-quality website is bound to bring higher traffic and link exchange, thus improving the website search ranking.
1.3 Effect analysis The author takes a website as an example. Before the implementation of SEO, the core keywords of the website could not be seen in the natural rankings of Baidu and Google, with only a dozen pages included. Potential customers could not find the company's website through the search engine, which greatly affected the development of the company's business. After more than two months of continuous optimization, the website has achieved good rankings in major search engines, Some new technologies are proposed, such as dynamic interface selection, two-way download, intelligent node elastic overlay network and so on. Some people believe that in the future enterprise informatization applications, "all types of enterprise networks will eventually evolve into P2P networks". However, the author believes that the P2P structure is not perfect. The problems of bandwidth occupation, protocol standards, complicated maintenance and expansion due to different computer configurations and uses in the system, and security risks also need to be solved. In addition, the characteristics determine that this structure needs a certain number of users to give full play to its advantages, so it is difficult to apply and promote it in SMEs. Therefore, at present, although P2P architecture has made some achievements in the construction of new digital campus, it is still a long way from the popularization of enterprise informatization.
The progress of technology and the improvement of the software and hardware environment can make up for the original shortcomings and make the classic architecture glow with new vitality, while the emerging architecture may also lose its advantages and reliance. The specific system structure depends on the characteristics of the project and the nature of the end-user group. Compared with advanced technology, users are more concerned about reliability, speed and convenience. Therefore, when selecting an architecture for an enterprise, system developers should not only consider the needs of actual business applications, but also take a holistic and developmental perspective, adapt to the overall needs of enterprise informatization process and future scale expansion, and avoid repeated investment; We should not only avoid blindly chasing new and increasing risks, try to use mature technologies, but also keep pace with the times, dare to try and innovate, and adapt to the requirements of the development of the times. In the future, the construction of enterprise information system will inevitably move towards the goal of integration, high efficiency, low cost, easy use and maintenance. Although P2P technology requires less hardware environment, with the reduction of hardware cost, cloud computing technology is more likely to be accepted and adopted by future enterprise informatization construction.
2 Future trend -- application of cloud computing technology Cloud computing can be said to be the hottest topic in the current software industry, and IBM, Yahoo, Google and other companies have invested in this field. It is the development of distributed processing, parallel processing and grid computing, or the commercial realization of these computer science concepts. As a resource delivery and use mode, cloud computing refers to obtaining resources (hardware and software) required by applications through the network. The network providing resources is called "cloud". "Cloud" is a number of virtual computing resources that are self maintained and managed by software, usually some large server clusters, including computing servers, storage servers, broadband resources, etc. The reason why it is called "cloud" is that it has the characteristics of cloud in reality in some aspects: huge volume; The scale can be dynamically scaled; The boundary is fuzzy, the position is erratic but exists. The characteristics of cloud computing enable application service providers to get rid of cumbersome details and focus more on business requirements. Access to computers and storage systems based on these features is conducive to innovation and cost reduction. End users do not need to buy expensive software and hardware products, or even professional IT maintenance knowledge. They can use rich product resources as long as they use browsers to connect with the Internet. The software manufacturer providing the product only charges the corresponding service fee. Some people call this feature of cloud computing "using IT infrastructure like water and electricity". Enterprises, especially small and medium-sized enterprises, adopt cloud computing technology for informatization, which can ensure that technology advances with the times; Products effectively integrate information resources to overcome the drawbacks of repeated construction and low-level construction; Full function, fast response and good security; Personalized, easy to use. Of course, the biggest benefit of cloud computing for enterprise informatization is that it greatly reduces the cost of software and hardware development and maintenance, reduces the burden of enterprise managers, and provides a feasible informatization path for enterprises in the global economic crisis. Technical enterprise management software has not only attracted wide attention, but also performed well in the management practice of some enterprises. However, as a new thing, it is inevitable to face many questions and challenges. There are still disputes about how to change ideas as soon as possible and how to provide security standards for customers. Therefore, its practical application effect remains to be tested by time and market. This article was published by Beijing Website Construction Company Shangpin China //ihucc.com/
