1、 Introduction to search engines
Recent studies and research have found that PR is also a very important factor for search engines to measure the quality of a website. Low PR websites, whether for exchange of friendship links or cooperation in other aspects, are a very important factor for search engines to measure the quality of a website. The most effective way to improve PR is to have websites with high PR. This kind of thing is the reason why many new stations seek external war connection, and it is also one of the low-cost strategies! For Baidu, the website with new snapshots and many daily updates usually has a high weight, especially some news portals. The information released will be included within half an hour. If you do link advertising on such websites, I believe it will improve your ranking. But the same update speed is also fast!
2、 Front and back office
1. Fluidic sense
When people read certain information, their vision always has a natural flowing habit: what they see first, what they see later, and what they see again. Research in psychology shows that the general browsing habit is from top to bottom, from left to right, on a flat surface, stable and depressing. Similarly, the plane is left loose and right stable. Therefore, the visual influence of the plane is stronger above than below, and the left side is stronger than the right side. In this way, the upper and middle upper parts of the plane are called the "best view", which is the most preferred place. In web design, some prominent or recommended information is usually placed in this position. Of course, this visual process is just a feeling, not a fixed formula. As long as it conforms to people's psychological and logical order, it can be used more flexibly. In web design, flexible and reasonable use directly affects the accuracy and effectiveness of information transmission.
2. Page Frame and Layout
Web page layout can be roughly divided into "country" type, corner type, "T" type, "L" type, comprehensive framework type, Flash type, and change type, which will not be discussed here. In fact, when we design, we don't think too much about the form. For example, when we see a round thing on a piece of paper, it is easy to associate it with the sun, while some people associate it with the moon, etc. This is a form metaphor. The most important thing is to grasp the needs of customers, grasp the positioning of the website and make a reasonable framework layout.
① . Resolution
The overall width of a web page can be set in three forms: percentage, pixel, and pixel+percentage. Pixel is usually the most commonly used form in website construction, and industry websites are also included. When we design web pages, we must take the resolution into consideration. With the development of technology, we usually use 1024 * 768 and 800 * 600 resolutions. Now, most of the web uses 778 pixels in width. Below the 800 resolution, the whole web page is often oppressed and feels airtight, In fact, this width refers to the widest width of a web page at a resolution of 800 * 600, which does not represent the best vision. Try 760~770 pixels, and you can achieve better visual effects at 1024 or 800 resolutions.
② At present, the advertisements of reasonable advertisements on some websites (pop-up advertisements, floating advertisements, big advertisements, banner advertisements, banner advertisements, etc.) make people feel very cumbersome and unwilling to see them. Sometimes even your website is not available, so the website is seriously affected and the advertisements fail to achieve the purpose of advertising. These problems are one of the contents that we need to consider and plan before designing the website. There are two kinds of floating advertisements. The first is advertisements that can float up and down in the spare places on both sides of the web page, and the second is advertisements that move randomly around the full screen. It is recommended to use the first type as far as possible when the first type can be used, and try to control at most one in quantity when the second type is unavoidable. If the number is too large, it will directly affect users' psychology and prevent users from browsing information, which is counterproductive. Home page advertising should not be too much moderate. For example, it is better not to appear too many other irrelevant content on the page of registration or a purchase step to distract users and avoid customer loss
③ . Rational use of space
A lot of web pages have a feature, which can be described in one word as "blocking". It puts all kinds of information, such as text, pictures, animations, on the page without considering how much information is crowded and how much information is not standardized. As a result, many inconvenience will be encountered when browsing. The main reason is that there is no distinction between the primary and secondary pages, the dominant page, or there is no focus, Without good classification, the whole is like a hodgepodge. It is difficult for people to find what they need. Some are out of balance in a blank space, which can also be described as "scattered". It is not necessary to fill the whole page without feeling empty, nor to make the whole page empty without feeling full. As long as reasonable arrangement and organic combination are made to make the page balanced, even if a large area of space is left on one side, it will not make people feel empty, on the contrary, it will leave a broad space for thinking, give people aftertaste and achieve visual effects.
④ . Text layout
In web page design, the handling of fonts is as critical as the handling of other design elements such as color, layout, and graphics. 4.1 Graphical text Graphical text is the expression of words in the form of pictures. This form is most commonly used in the sub columns of the page because it is prominent, while beautifying the page, making the page more humanized and enhancing the visual effect. It is beyond the reach of words. The disadvantage of universal websites is that they are not very extensible. 4.2 Emphasize that if individual words are the focus of the page's appeal, you can consciously strengthen the visual effect of the words by means of bold, underlined, enlarged font, indicative symbols, slanted font, and changing font color to make them stand out and stand out in the overall page. These methods actually use the law of contrast. If the update frequency is low, you can also use text visualization.
3. Tutorial Introduction
It is difficult to say the network background technology is complex, but it is absolutely essential to have a good textbook. In the face of various books in the market, which one should I choose? A little red in the green. That is the three background solution books in the website construction complete manual series recently published by the "Rain Man" website construction team: Website ASP Background Solution, Website JSP Background Solution, and Website PHP Background Solution.

3、 Prospects of website production
In recent years, the website production business has been rising rapidly, and the industry market is growing. The market demand should be large, and the business popularization work is also in place. Many industries have formed a situation of competing to build enterprise websites, make web design, and carry out network marketing.
The application of new technologies will make the construction and production of enterprise websites more attractive. With the integration and development of technology, many popular technologies in other industries, such as video, 3D animation, virtual reality and other technologies, have been transplanted to the Internet. In the near future, they will appear in the production of enterprise customer websites; The new network programming language (. net technology) and server CDN (content publishing network) technology will also make the website production structure more compact, access more smooth, and better adapt to new requirements.
Of course, website optimization services will be integrated with website production to provide integrated services. Enterprise customers are no longer satisfied with making a website, and then carry out their own online marketing activities. Internet companies also need to develop targeted online marketing strategies for enterprise customers and implement them, so that enterprise website construction can really play a role and bring tangible results to customers. This puts forward higher requirements for network companies, and website production practitioners must strengthen self-learning and improvement to meet this requirement.
Personalized personal website design, personal theme website production and other forms of personal website production services have begun to appear, and personal website production and design services will become a new business growth point.
4、 Website development technology
1. Framework knowledge
Architecture is an important part of large-scale website development. Developers have benefited from website architecture tools provided by Rails, Django and other companies, because architecture tools can help complete repetitive tasks that require some programming knowledge. If you have leading architecture technology (such as Rails, Django, CakePHP, Symfony, etc.), your career choice will be very broad.
2. Widget Development
Widgets are mini applications embedded in web pages, which can also be downloaded to Windows or Mac desktop to run. It makes data more portable and interactive. Well known ones like Yahoo Widgets and AOL Music Widgets. In addition to mastering the language knowledge required for network application development, the development of form widgets also requires proficiency in Javascript and Flash.
3. Custom CMS themes
Nowadays, more and more people begin to use CMS (content management systems, such as Wordpress and Drupal) to build their websites. It is conceivable that it is impossible for everyone to use the default theme provided by CMS. In order to make their own CMS website unique in appearance design, we need some technicians dedicated to CMS theme development.
4. CMS Customizations and plugin development
Similarly, with the popularity of CMS, the demand for CMS function customization and plug-in development is growing.
5. PSD to XHTML services
In the process of building a website, many companies first use Photoshop to design the original appearance of the website, and then convert it to XHTML. This requires a strong knowledge of CSS/HTML.
6. Javascript Plugin creation
Javascript Framework is very popular because it makes code development of Javascript easy. For example, if you develop excellent plug-ins based on the popular Javascript Framework - jQuery, your plug-ins will become popular.
7. Facebook/MySpace applications
Facebook/MySpace, the two major social networking sites, have become popular in the United States. Developing applications for them is, needless to say, quite popular.
8. iPhone applications (iPhone application development)
Similarly, developing applications for iPhone can always be downloaded in large quantities, so it is also a very profitable job.
9. E-commerce integration
Nowadays, the cooperation between e-commerce websites (such as eBay and Amazon) and online banking service systems (such as Paypal and Google Checkout) is getting closer and closer, so the development of e-commerce trading platforms is also very promising.
10. Flash and Actionscript Knowledge
More and more companies use Flash to create their own websites and display their products, because beautiful animations are always easy to attract people's attention. Therefore, Flash animation technology is bound to develop rapidly.

According to my recent understanding (website construction), good websites are not necessarily ranked according to their age. Good websites are highly useful and popular with network users. In addition, since the website applied for the domain name, it is necessary to manage and maintain the website in the later period. This is the fundamental way for the website to stand in the current world.
