What is seo code optimization

Source: Shangpin China | Type: website encyclopedia | Date: June 21, 2012
The execution efficiency of JS is also far lower than that of HTML, so try to use less JS and encapsulate all JS code into external call files. This will not occupy an important position on the page. JS optimization is to prevent JS code from occupying an important position and space on the page. Search engines do not parse JS content. It can also simplify a lot of code and speed up page display.

Search engine has become one of the important ways to promote websites. According to statistics, with the development of Internet technology. 80% - 90% or more of the traffic of small and medium-sized websites comes from search engines. However, in general Website construction Due to the lack of professional marketing knowledge and ideas, the company only set out to build the website from the technical perspective, ignoring the inclusion and retrieval rules of the search engine, thus failing to achieve the purpose of website promotion. Therefore, if the enterprise website wants to succeed in website promotion, code optimization at the website design stage is an essential work.

1. Introduction to code optimization

Make necessary adjustments to the HTML source code in the web page to improve the friendliness of the page. Code optimization is an important part of search engine optimization (SEO), so as to improve the efficiency of spider crawling the web page. After code optimization of the page, on the one hand, it can clear or simplify the redundant code in the page, reduce the size of the page, and speed up the download of the page, thus improving the user experience of the page and the friendliness of the search engine; On the other hand, it is conducive to highlighting the theme of the page and improving the relevance of the page.

2. Code optimization strategy

The strategy of code optimization mainly includes: head optimization strategy, code reduction strategy, weight tag strategy, and image and Flash optimization strategy.

2.1 Head optimization strategy

Including the optimization of page title (title page MA TA tag). Head optimization is the most important content of website search engine optimization.

2.1.1 Title

The HTML code format is that when optimizing the page title, the page title is the text that appears on the left side of the title bar of the browser window. The length of the title should be controlled within 40 characters, with 2030 Chinese characters as the best; The layout of keywords should highlight the theme of the page, and the more important keywords are placed in the front position; The word frequency of the primary key should be arranged reasonably, so that the primary key appears no more than 3 times, and each secondary key appears only once.

2.1.2 MA TA label

MA TA tag optimization is mainly aimed at Keyword tag and Description tag.

Keywords used to express web pages. When designing a Keyword tag, the Keyword tag is a hidden tag. It is necessary to carefully select several core keywords and their combinations (preferably 3-5, preferably not more than 15). Different keywords should be separated by half commas, but try to prevent all pages from using the same Keyword

It can be described with a few simple natural sentences. The Description tag is a summary of the content of the web page. When designing the Description tag. However, the description content should be highly relevant to the page title and the main content. The number of words should be controlled within 200 characters. The keywords can be repeated three or four times, but try to prevent all pages from using the same Description

2.2 Code reduction strategy

The simplification of page code includes: garbage code cleaning, CSS optimization, JS optimization and table optimization.

Rare examples include spaces, default attributes, comment statements, and empty statements. For the space characters at the beginning and end of each line * *, garbage codes are generally generated by the page creation software. You can use Dreamweaveor EditPluand other software to clean up, and about 70% of the garbage code can be deleted. For default attribute codes, such as left aligned attributes, you can use the Dreamweavereplace function to clean them. For comment statements, you can delete the comment statements that do not affect the readability of the web page source code. For empty statements in the code, you can use the specific functions provided by the web page creation software, such as Dreamweaver's HTML/XHTML cleaning function. In addition, writing HTML code manually can prevent the occurrence of garbage code.

CSS technology can effectively control the page accurately. But at present, search engines do not parse CSS content, which is called cascading style sheets. So try not to scatter CSS in HTML tags, but encapsulate it into external call files. This can effectively reduce the amount of page code, do not occupy an important position at the top of the page, and is conducive to the search engine to capture the relatively important content of the page. In addition, try to use P+CSS to layout the page. P+CSS can not only make the page code concise and easy to revise, but also be very friendly to users and search engines.
