CSS is one of the most useful ways to separate the expression of code from the actual content, and it is also a way to optimize the search engine, usually a set of CSS style standards are created in the site design, which are stored in a separate file with the extension CSS. Then use HTML tags to design the Web page, you will use the content of the CSS file. Three simple but effective design techniques to guide you in using CSS to improve the design of your site so that your site can rank in most search engines.
First, using CSS technology to build files
First of all, consider the operation of the search engine. Search engine robots Enter the site, browsing the content on the site, because these tools do not waste too much time to find, so the content of the site is easier to search the better. In view of this problem, some of the structure of the Web page is not necessary, this time to be removed. In a separate CSS file, these structures are easier to store. This means that a small number of HTML tags will be used instead of those that do not have any relation, since CSS rules can be used to better arrange HTML tags. After removing a large number of superfluous marks, only the content of reasonable arrangement is left. This makes it easier for search engines to find sites and index sites.
Second, using CSS to create images
The traditional way of using images to switch between links is to use some of the relatively complex switching functions in JS. JS encoding is not the real content of the Web page to render, just some irrelevant language, it is very unfriendly to the search engine, so if in the Web page too much use of this technology to deal with content, will affect the site in the search engine rankings. Using CSS to design a Web page is a better approach. Use 2 kinds of graphics to create text links in Web pages and use CSS to design layouts. In HTML, the link content is displayed, the length and width are designed, and then 2 images are defined as two different backgrounds, one image is rendered when the mouse leaves, and the other appears when the mouse clicks.
Third, the use of CSS design title tags
We know that search engines will focus on searching the site to find the title, for example, Heading 1, Heading 2, Heading 3, and so on. When designing the title tag, many inexperienced designers have a headache: The browser is presented with a lot of hard-to-read black information. This time to use CSS, it can make the title design pattern more reasonable, text content can attract search engines to search. And such a perfect article is more attractive to the eyes of the visitors.
