There are many ways to improve the performance of WordPress websites. Images and other media files are the biggest reason for long loading times. In other words, implementing image optimization methods will have a significant impact on site performance, and delayed loading is no exception. This paper introduces the working principle of delayed loading and its benefits to the website. Then, we’ll show you the most popular way to add deferred loading for various types of elements in word press. Finally, it describes the most common technical problems that this setting can cause.
let’s go! What is YouTube channel subscription lazy loading? Typically, when you visit a web site, all components try to load at once. The browser displays all media assets, text, links, and other elements on the page. If there are many media assets (such as images) on the page, the loading time may be greatly reduced. There are many ways to reduce the impact of images on page loading time. You can optimize images, enable browser caching, use CDN (content transfer network), and choose smaller file formats. Ideally, there is no website too fast, so more efforts need to be made to optimize as much as possible.
Deferred loading does not change the image file size or the time required to load for each user. Instead, this setting allows the browser viewport to delay loading each photo until it reaches the part of the page where the file is located. In fact, if there is already a reactive website loaded late, it has the least impact on the way users interact with the website. Most visitors don’t notice the image when scrolling the page. At the same time, users do not need to request and load all images at the same time, so they can enjoy the benefit of speeding up the initial load time.
What are the advantages of delayed loading in WordPress? Delayed loading may contribute to the initial loading time. If the loading time exceeds 3 seconds, this is necessary considering that 40% of users will leave the web page. Therefore, this setting can guide visitors to navigate content on the site. In addition, delayed loading can also reduce the burden of memory and storage. Therefore, you can choose a cheaper website hosting plan. By default, starting with WordPress 5.5, CMS (content management system) will delay loading images. However, there is some controversy about whether the default method will damage the core web vitals score.
By default, delayed loading increases the time it takes to load paper. But this will also affect the LCP (large contentative paint) score. The LCP measures the time required to load the largest image or text block from the page. Male WordPress uses the HTML loading = lazy attribute in the image of the website. In general, this is the easiest way to implement deferred loading. However, not all browsers support this property. To disable delayed loading of a specific image, its properties must be manually modified using HTML. The alternative is to use the WordPress plug-in to implement delayed loading in other ways (providing more control).
Do other elements have delayed loading? Technically, you can delay loading almost all elements on your site. Delayed loading works amazingly with images and is also the killer of video assets. In addition to media assets, you can also delay code loading, such as JavaScript and CSS. In fact, to improve the score of FCP (first contentative paint), you can block the script rendered on the website
Delaying the image in the invisible part may affect the FCP score. It may also affect users’ first impression when visiting the website. A simple solution is to disable delayed loading of images of page titles and other parent elements. For example, it is recommended to disable (1) delayed loading of logos and (2) header backgrounds on this page. Male WordPress needs to add code on the website to disable the basic implementation of delayed loading. The easiest way to turn off deferred loading of specific media assets is to use plug-ins (such as 3 lazy load), as described in the previous section. Delayed loading causes the layout to move. Layout movement occurs when the page is loaded and moves when the element is displayed. CLS (cumulative layout movement) is the core web vital that measures layout movement. In some cases, improper implementation of delayed loading may affect the CLS score of the website. All elements on the page are not loaded at once. Conversely, processes are processed one by one, even if they are almost immediately visible in the browser. If the image file is loaded after other elements, the asset can be moved. The solution to this problem is that word press does not use full-size images. After uploading photos to WordPress, CMS will automatically resize photos with standardized resolution. Using standard resolution, the possibility of sharp layout changes will be reduced even in delayed loading. You can also manually specify the image size for each file. But this is a time-consuming process. In summary, it is recommended that you do this only for images that you want to display in a unique size. Deferred load and cache plug-in problems cache plug-ins often conflict with deferred load tools. Some cache plug-ins (such as WP rocket) have built-in deferred loading function. Conflicts often occur when using this feature with deferred load plug-ins, such as A3 lazy load. It is recommended to use a set of plug-in products to prevent images from being invisible due to conflicting tools. If both the deferred load and cache plug-ins are active and errors begin to appear, it is recommended that you disable the previous option first. After disabling the delayed loading plug-in, make sure the image is loaded correctly. In this case, the caching tool may have built-in deferred loading. That is, there is no need to set up other software for this function. Conclusion delayed loading is a part of the core function of WordPress, but there are ways to improve its implementation. 3 using plug-ins such as lazy load can better control the delayed load on the site. The correct plug-in can also configure and eliminate delayed loading of external assets. According to the implementation of delayed loading, the page loading time should be greatly reduced. The more media on the website, the smaller the negative impact on the user experience, and the better the result. How does WordPress use deferred loading?
