How to Improve Website Loading Speed

I. General Methods for Improving Website Loading Speed

1. Avoid Redirection
   Redirection can be simply understood as the automatic jump of a webpage. The most typical situation is that the URL corresponding to the keyword submitted by the customer is not exactly the same as the URL finally opened when the potential customer clicks the keyword.
2. Simplify Web Page Elements and "Slim Down" the Web Page
   It is likely that Boda Xing Website Construction Company has thought about "slimming down" the web page since the beginning of website construction. We can use the webpage save - as function and browser plugin tools to check the web page size. Generally speaking, the smaller the space occupied by the web page itself, the faster it will load. Avoid using large - sized flash, images (and image friendship links), videos, audios, etc., or replacing these elements with text as much as possible to help reduce the web page size.
3. Delete Flash Pages
   Flash pages generally refer to pages composed of flash or javascript that do not display the web page content. Whether from the perspective of website loading speed or user experience, flash pages are not popular among users. If it is determined to use flash pages, it is recommended to place a prominent skip button in a prominent position on the page to provide a quick access channel for potential customers who are in a hurry.
4. Reasonably Place Statistical Code
   If the customer's website has enabled a counter to统计 the website's access traffic, it is recommended to place the statistical code directly at the bottom of the page code. In this way, if the counter fails and cannot be accessed normally, it will not delay the overall website loading speed.
5. Optimize Web Page Design
   Divide the web page content into reasonable blocks and use multiple tables. Try to use static HTML pages (rather than dynamic pages such as asp, php, jsp). Do not use overly complex web page background and navigation bar designs. If there is no special need, do not use overly complex CSS or javascript special effects, which will appropriately improve the web page loading speed.
6. Provide Progress Display
   If the web page loading speed is really slow, or if downloading files takes a long time, it is best to provide a progress display (loading) for potential customers to help them understand the progress status and guide them to establish a time prediction. This way, they won't mistakenly think that the page cannot be opened or that it takes too long and then close the web page.

II. Other Aspects to Consider

1. Standardize Website Program Coding
   Nowadays, many websites are developed based on dynamic interactive technologies, which greatly facilitate the maintenance and update of website content. However, dynamic data access technology will inevitably use many judgment, loop, and conditional statements. A slight carelessness can lead to forgetting to end judgment statements, forgetting to close loop statements, etc. Another typical oversight is forgetting to close the database after reading and writing data. All these can cause the website to run slowly or even fail to run normally. For example, sometimes, after causing a dead - loop, the website continuously consumes server resources after opening, eventually leading to the website being unable to run.
2. Ensure Good Server Line Configuration
   The slow loading speed of a website is largely caused by the unstable operation of the server. Nowadays, in every place, there are many enterprises engaged in server leasing and hosting. Due to differences in computer rooms, line resources, and server configurations, the prices vary greatly. Even for servers with the same configuration in the same computer room, the number of websites hosted on the host will also affect the operation quality and stability of the website. Compared with website construction and development, which can cost tens of thousands or even hundreds of thousands of yuan, the cost of a server (especially the virtual hosts used by most enterprises) can be negligible.
3. Choose the Appropriate Image Format
   Generally, there are three image formats used on web pages: jpg, png, and gif. The specific technical indicators of these three formats are not the focus of this article. We only need to know when to use which format to reduce the web page loading time.
   • JPG: It is generally used to display photographic works such as landscapes, portraits, and art photos. Sometimes it is also used for computer screenshots.
   • GIF: It provides fewer colors and can be used in places where the color requirements are not high, such as website logos, buttons, emojis, etc. Of course, an important application of gif is animated images.
   • PNG: The PNG format can provide a transparent background. It is an image format specially invented for web page display. It is generally used for web pages that require a transparent background display or have high requirements for image quality.
4. Reduce HTTP Requests
   When a visitor opens a web page, the browser will send many object requests (images, scripts, etc.). Depending on the network latency, each object loading will be delayed. If there are many objects on the web page, it may take a long time. Therefore, it is necessary to reduce the HTTP request burden. How to reduce the burden? 1. Remove some unnecessary objects. 2. Combine two adjacent images into one. 3. Merge CSS files. For example, if you need to load three CSS files, you can merge them into one to reduce HTTP requests.
5. Large and Bloated Databases Due to Excessive Content
   This reason is often overlooked, but it does exist. Since most enterprise websites now use the Aceess small - scale database, there are strict requirements for the number of data read - write exchanges. Generally speaking, a small - scale website can support reading and writing tens of thousands of pieces of data with Access, but when it exceeds 100,000 pieces or more, its efficiency will be greatly reduced. Moreover, when the database volume reaches more than 30M, the read - write and retrieval speed will drop significantly. Correspondingly, the website data loading speed and page opening speed will also drop significantly. Many websites, especially many small websites, can't find the reason for the slow running speed. Checking the database may suddenly make things clear.
6. Other Small Tips
   • Remove Unnecessary Loading Items: Get rid of any elements on the website that are not essential for its core functionality. These could be unnecessary scripts, plugins, or widgets that are slowing down the loading process.
   • Choose Fast Widgets: If you embed widgets from other websites on your web page, if you have a choice, always select the ones that load quickly. A slow - loading widget can significantly impact the overall loading speed of your site.
   • Use Images Instead of Flash: Whenever possible, use images instead of flash elements. Flash can be resource - intensive and may not be supported on all devices. Using images also has benefits for SEO.
   • Staticize Content When Possible: If some content on your website doesn't need to be dynamically generated, consider staticizing it. This reduces the server's processing load and can speed up the loading of that particular content.
