Secondly, the ranking of keywords is also related to the opening speed of web pages (reference: important factors affecting keyword ranking), which mainly reflects that the search engine has a good user experience, and the ranking is better than other websites. therefore, I think it is necessary for us to improve the opening speed of web pages, which does not require too much cost investment, just need to pay more attention to some tips! Here are some tips for your reference:

1. Optimize css. We know that the emergence of css separates the expression of content and elements. Users open web pages designed with css. Css is generally downloaded to the user's local computer, unlike the html element performance tag. Every web page of the site has to be called once, using css, just once! In addition, css can replace pictures in some places, which is why div+css is advocated now! However, there is also some extra css code to write css using dw. If Css is too bloated, it will also affect the speed of the web page. Here is a tool cleancss for you to try. It is an online tool. In addition, it is really difficult for beginners to simplify the code by hand. however, it will be helpful to read more articles that simplify css skills. If you read more, you will know that the code can be streamlined.

two。 Optimize the picture. There is no skill in this, and it can be done through software. I like to use ps, select the format used to store web in ps, and then select options such as the quality of the picture. The picture looks clear and the size is right to save it.

3. There is a problem with picture format. It is very important to choose the correct picture format. Jpg is generally used for photos or true color pictures, gif for flat color pictures, generally used for buttons or logo pictures, png and gif are very similar, but support more colors!

4. The problem of marking the length and width of the picture. This problem can generally be seen in html, and some people often forget to write about the length and width of the picture. These marks tell the browser the size before opening the picture, and the browser retains an area when it loads the page, speeding up the display of the entire page.

5. Learn to use "/" in url. When a user opens a similar url and there is no "/", the server needs to determine what type of file or web page, then you add a "/" to the URL, and the server knows that it is a directory page, reducing the loading time.

6. Reduce the number of responses to the web page. For the opening of web pages, it is actually a very complicated process. From the application to open the web page, to the web server response, compilation and other actions, and then send it back to the browser to display the text and pictures in front of us, multimedia files and so on. So I want to reduce the number of responses as much as possible, and now ajax is doing well in this area. Of course, a static page is an exception, static pages pay more attention to picture size and web design on the line.
