1, standardization of some codes of magnetic head.
The header code is the entry part for search engines to crawl websites. At present, the header codes of many websites are quite uniform, and the stereotype effect is obvious. This kind of website code is not as popular with spiders as template framework. What we need to do is to standardize the code of the website, establish the unique header of the website, and make the search engine fresh, thus attracting spiders to crawl.
2. Layout the web page with DIV+CSS.
Although div+css is very mature now, considering the compatibility of web pages and the simplicity of layout, many web designers may still use the old-fashioned table layout. Although table layout is convenient, its disadvantage is obvious, that is, it will greatly increase the size of the web page, especially the nesting of multi-layer tables. This layout will not only improve the volume, but also affect the crawling of search engines and the inclusion of sites if there are too many nests.
3.CSS optimization
CSS is a very important part of page effect presentation, including color, size, background and font. Writing CSS is easy, but there are still many skills to write refined CSS code.
(1), CSS position
Css shows that if it appears behind the website, the page needs to be re-rendered, and the opening speed will be affected. All CSS definition codes should be placed in front of the website.
(2) csssprite technology
Some pictures on the website can be merged by csssprite technology, which reduces the number of loading requests and improves the loading speed of web pages.
(3) CSS code optimization
By shortening css code attributes, removing redundant structures, resetting and a series of methods and technologies, css codes are simplified and the size of css files is reduced.
(4) Try not to use embedded CSS.
There are two kinds of embedded CSS, one is the common embedded CSS in the head area; The second is the embedded CSS that appears in the tag. No matter how CSS is embedded, the page size will increase. In this regard, we can try to use external CSS to reduce the size of website pages.
This is only part of the function of the code in the website, and there may be more other factors that affect the website. SEO optimization of website page code can not only improve the opening speed of web pages, but also improve the user's access experience. At the same time, from the perspective of SEO, it can also improve the access speed of spiders and help search engines index websites.
Code is the core of website construction, and the code itself has many internal components. How to build a website that is easier to optimize and better displayed is the core issue of enterprise website construction.
