In a word, even slow website opening will lead to user loss. The website opening speed and page response time are often seldom noticed by SEOer, but this can increase the loss of website users, because in the eyes of some users, if your webmaster cannot be opened for a long time or has a long response time, your website image will be compromised in the user's mind or your website is not a regular website, because in their eyes, the speed of opening regular websites should be fast, and only those websites that do not enter the stream can open at such a slow speed, so, generally, companies that are interested in the image will take this optimization measure to speed up website opening. In fact, there are many factors that will affect the website opening speed, and each item does not have a great impact on the website opening speed. However, over time, there are more and more factors that affect the website opening speed, as a result, the website speed slows down and the user experience is reduced. Therefore, website optimization does not work in one breath, but requires daily patient maintenance. Today, I will show you the reasons for slow website access.

1. unstable space

In general, space instability is a direct factor affecting the speed of opening a website. many new users are afraid of website troubles, saving the domain name record filing process, in addition, domain names that do not apply for ICP filing can only be used for foreign spaces, which leads to the use of foreign space for many new users to create websites. Although the overseas space can be used without record filing, accessing the overseas space in China will prolong the response time, and the overseas space is not stable in China. The Baidu Lee team said that Baidu would crack down on non-filed domain names, but Baidu has not implemented it yet because Baidu has already cracked down on junk content after so many algorithm updates, however, the amount of information on the Internet is small and it is difficult to meet the needs of some users. many websites that have not been filed have high value, so they are not implemented yet, when Baidu has enough information, your website may be in danger. Therefore, you must file records for your website for future stability.

2. flash

There are many websites. in order to make your website look more beautiful, add flash files to the website so that the core content of the website can be played by users in flash mode. In fact, if you access this page for the first time without the cache in your browser, you will find that the flash content needs to be loaded and the flash content is not very stable, if the user's network speed is not very good or your space is unstable, flash loading will fail, which will affect the user experience. From the perspective of optimization, the spider will not read the content in your flash, and of course, the spider will not capture the flash content in your website, so in the eyes of the spider, some of your websites will be blank. Therefore, adding flash content to your website will not only affect user experience, but also affect website optimization. If you want to make your website look more beautiful, you can learn the code and use the code to achieve flash playback. this will increase the user experience and facilitate optimization.

3. dead links

The dead link is a page that does not exist in the residual website after the website is upgraded and upgraded. that is to say, the page before your website is changed is deleted after modification, however, the search results have already included this page, and such a page is called a dead link. after a user accesses a dead link page indexed by Baidu, the page may be blank or cannot be opened, for such a link, we need to create a 404 File, write the dead link to the 404 file, and submit it to the Baidu webmaster platform. In fact, 404 serves as a jump. when a user accesses a dead link page, the page will be blank. However, after 404, when users access the dead link page, they will directly jump to the homepage of our website, but too many 404 pages will also affect the website opening speed. Therefore, we need to submit the 404 page to the Baidu webmaster platform, for example, Baidu applies to remove the dead link page, so that users will not access our Dead link page through the search engine.

4. image compression

If a website contains too many images, the website can be opened slowly. for example, for decoration or tourism websites, users have high Image requirements, for example, users in the decoration industry have high-definition image requirements, as well as a full set of images and small-sized apartment decoration images, which also include price requirements, from the analysis of these user needs, we can see that all user needs are based on images. Therefore, we must update a large number of HD images every day to meet user needs, this will greatly increase the opening time of the website. in this case, we should compress the images of the website to reduce the space occupied by the images, this greatly reduces the loading time when users access the website.

5. plug-ins

For plug-ins, the website installation plug-in is of course useful, so we will install this plug-in, but if a website has too many plug-ins, it will affect the website opening time, for example, some DZ forums have dynamic and beautiful plug-ins. after installing this plug-in, although it can make the forum look more beautiful, however, any operations we perform on the forum will increase the response time for the appearance of this plug-in. Therefore, we try to install some necessary plug-ins when installing the plug-in on the website, do not install useless plug-ins as much as possible. we can understand the plug-ins as that, for a website, you feel that the user's visual effect is important or the user's time cost is important, in this way, you can determine whether or not to install this plug-in.

6. high-load access

If your website is well-known or popular, and the website has a high access volume every day, then you need to consider whether you should change to a server with a relatively large memory. compared with the general space or server, the access volume is also limited. for example, when your website has one hundred online visitors, your website will be in a high load state. in a high load state, any operations on your website may cause the website to crash, if our website traffic is relatively high, we must replace a server with a large space.

7. program problems

Few people usually use SEO and programs at the same time, so many SEO websites will choose some free secondary development programs. of course, these programs do not follow their own ideas after all, so there will certainly be some unsatisfactory points, which requires us to adjust JS calls in the code of the program. when there are too many JS calls problems in the website, this will increase the response time of your page, because the response time of JS program calls is added when you access your website. Therefore, when selecting programs for secondary development, do not make too many modifications.

Conclusion: although the reason for slow website opening speed can be solved through optimization, as long as your website continues to operate, there will still be factors affecting the website opening speed every day, even if we have optimized our website, we need to maintain it for a long time so that our website remains healthy.
