What should I do if the website visit is slow? Detailed explanation of common reasons and optimization methods

in the Internet traffic competition is becoming increasingly fierce, the efficiency of website access is directly related to user retention and business transformation. Once the problem of slow website access occurs, it will not only make visitors lose patience and leave directly, but also affect the weight rating of the website by search engines. Many webmasters often have no way to start when encountering such problems, and do not know whether it is a problem with the server, code or resource allocation. This article will comprehensively dismantle the common incentives for slow website access, and combine practical optimization methods to help webmasters accurately locate and solve problems to improve the website access experience in an all-round way.

, the site access slow core server incentives?

server is the basic carrier that supports the operation of the website. Most of the problems of slow website access can find the root cause from the server level, which is also the primary direction of webmaster investigation.

1, insufficient server configuration

many small and medium-sized websites in the early stage in order to control costs, will choose low-end servers, when the site visits surge or run large programs, CPU memory and other resources will be quickly occupied, resulting in a significant decline in data processing speed, and ultimately lead to slow website access problems. For example, during the promotion of e-commerce websites, if the server configuration can not keep up with concurrent visits, there will be a situation where the page load card cannot even be opened.

2, server line problems

server's line nodes and bandwidth limitations will also affect the speed of website access, if the server uses a single line, cross-regional access needs to go through multiple transit nodes, data transmission delay will increase significantly; and insufficient bandwidth will lead to a large number of visitors at the same time When visiting, data transmission channel congestion, thereby slowing down the efficiency of website access.

Second, the website access slow code and resource problems?

in addition to server factors, the quality of the code and resource allocation of the website itself are also common internal reasons for slow website access.

1, Redundant Code and Unoptimized

part of the website development will leave a lot of redundant code, undeleted test scripts, or use unopened open source programs, which will increase the burden of server analysis, prolong page loading time, and directly cause slow website access. For example, some websites built with CMS systems have a large number of idle plug-ins installed, and the redundant code of the plug-in will slow down the overall operation speed.

2, static resources uncompressed and optimized

static resources such as pictures, videos, CSS and JS files in the website, if they are not compressed, the file volume is too large, which will greatly increase the data transmission time. For example, a few megabytes of high-definition original image is placed directly on the page, and visitors need to load pictures for a long time when opening the page. The intuitive feeling is that the website is slow to visit, and it will also consume more server bandwidth resources.

3. External factors affecting slow website access?

sometimes the slow access of the website is not the problem of the website itself, but caused by external environmental factors, such problems need to be investigated in combination with user scenarios.

1, guest network environment differences

visitors' own internet bandwidth, operator lines will also affect the speed of website access, such as users using mobile data networks, when accessing websites in areas with weak signals, the data transmission rate is limited, and website access will be slow; network interoperability between different operators Delay will also lead to loading cards when accessing across networks.

2, third-party plugins and scripts drag

many websites will embed third-party statistical codes, advertising plug-ins or social sharing plug-ins, these plug-ins need to load resources from external servers, if the third-party server responds slowly, it will block the overall loading process of the page, resulting in slow website access illusion, this situation is particularly common in information websites with more advertising plug-ins.

four, website access slow targeted optimization methods?

find the incentives for slow website access, we can take corresponding optimization measures in combination with the actual situation to improve the efficiency of website access from the root.

1, server and bandwidth optimization

according to website visits and business needs, upgrade server configuration, select multi-core CPU and sufficient memory models, and match multi-line BGP bandwidth to ensure that visitors from different regions and operators can quickly access the website; conditional webmasters can also configure CDN acceleration nodes, cache static resources to the nearest node server, greatly shorten the data transmission distance, and improve the website access speed.

2, code and resource compression optimization

regularly clean up the redundant code and idle plug-ins of the website, carry out lightweight transformation of the CMS program, delete unnecessary functional modules; use professional tools to compress pictures, CSS and JS files, such as compressing high definition pictures into WebP format, greatly reduce the file size without affecting the image quality, and open the browser cache function, so that visitors can directly load local cache resources when visiting the website again, reducing repeated requests.

To sum up, the problem of slow website access involves multiple dimensions such as servers, codes, resources, and external environments. Webmasters need to start with server configuration investigation, and then gradually optimize code and static resources, while taking into account the influence of external factors. Through targeted optimization measures, not only can we quickly solve the problem of slow website access, but also improve user experience and search engine ratings, laying a solid foundation for the long-term operation of the website.
