The article also examines what to consider when using image caching, optimization methods, software tools, and options. The advantages and disadvantages of lazyload are discussed, and the effects of image caching on SEO and the results of its use are evaluated. It is recommended that you consider this information to increase the speed and user experience of your website.

What is Image Cache and Why is it Important?

Image cacheis a critical technique that makes images on websites load faster. When a user visits a web page, the browser downloads the images from the server and stores them temporarily. When the same user revisits the same page or another page containing the same image, the browser uses the cached copy instead of downloading the image again. This significantly reduces page load times and improves the user experience.

Image cache Its main purpose is to improve the performance of websites. High-resolution images can slow down page load times, especially on mobile devices. Caching prevents these images from being downloaded repeatedly, making the website faster and more efficient. This allows users to stay on the site longer and engage more.

Advantages of Image Cache

• Faster Page Loading Times
• Reduced Server Load
• Improved User Experience
• Lower Bandwidth Usage
• Increased SEO Performance

The table below provides a comparison of different caching types and their features. This information can help you determine the most appropriate caching strategy for your website.

Also, image cache It is also of great importance in terms of SEO (Search Engine Optimization). Google and other search engines consider page loading speed as a ranking factor. Pages that load faster tend to rank higher in search results. Therefore, an effective image cache strategy can improve your website's SEO performance and help you attract more organic traffic.

What is Lazyload and How Does It Work?

Image cache An important part of optimization, lazyload is a technique that ensures that images and other media content on web pages are loaded only when they are in the user-viewable area. This method significantly improves the user experience by increasing the page opening speed. Especially on long pages with many images, the lazyload technique loads only the images in the section visible to the user, instead of loading the entire page. This shortens the initial loading time and reduces the load on the server.

The basic principle of Lazyload is to load only the content that is visible or close to being visible on the screen when the web page is first loaded. As the page scrolls down, new images start loading as they approach the visible area. This process is usually done using JavaScript. JavaScript codes detect when images enter the visible area and then activate the source addresses (src) of the relevant images to start loading. In this way, the loading of images in those sections is delayed until the user scrolls down to the bottom of the page.

Lazyload Application Steps

1. First, choose a JavaScript library for lazyload (e.g. Lozad.js, lazysizes).
2. In your HTML code, normally src instead of feature data-src Use the .source address feature to specify the source addresses of the images.
3. Add and initialize the JavaScript library to your page. This will ensure that images are loaded when they enter the visible area.
4. Using a placeholder while images are loading can prevent the page layout from breaking.
5. Customize Lazyload settings according to your website needs (e.g. loading threshold, effects).

Another important advantage of Lazyload is bandwidth saving. In cases where users do not need to see all the images on the page, loading only the displayed images saves users internet quota and reduces the bandwidth costs of the website. Also, mobile devices Considering the importance of page loading speed on the web, lazyload technique provides a smoother and faster experience for mobile users. Therefore, it is highly recommended to use lazyload, especially for mobile-focused websites.
