What is lazy load used for?

Optimizing a website is a key part of providing an excellent user experience and ranking effectively in search results. One tool that can significantly contribute to improving site performance is the Lazy Load technique, or “lazy loading.” In the previous part of this article, we discussed the basics of implementing Lazy Load. Now we will look in more detail at how this technique can be optimized and what benefits can be achieved.

Lazy load images

One of the main uses of Lazy Load is to delay the loading of images on a page. This is especially important because images are often the largest element of a page in terms of size. To optimize this technique, there are a few additional steps you can consider:

• Image compression: Before uploading images to your site, it’s a good idea to use compression tools that will reduce the file size without losing visual quality. This will allow images to load even faster.
• Lazy Load with cache: It’s also worth considering using technology with cache memory, which stores images that have already been loaded so that they don’t have to be downloaded again the next time the site is visited.

Lazy load for scripts

JavaScript scripts can significantly affect the loading time of a page. Therefore, it is worth considering which scripts are necessary for the page to run immediately, and which can be delayed. For example:

• Statistical scripts delay: Website traffic analysis scripts, such as Google Analytics, do not have to load immediately. They can be delayed so they don’t slow down the initial loading of the page.
• Lazy Load for external scripts: If your site uses a lot of external scripts, you can apply Lazy Load for them as well, so that they do not delay the loading of the page content.

Testing and monitoring

After implementing Lazy Load, a key step is to regularly test and monitor the performance of the site. There are tools that allow you to check the page load time and identify any problems. If the site becomes more responsive and fast, it’s a sign that the implementation of Lazy Load is having a positive effect.

Does Lazy load have an impact on SEO?

This question often troubles website owners. However, Lazy Load does not have a negative impact on a site’s positioning in search results. On the contrary, improving a site’s performance can positively affect its rankings.

Other site optimization techniques

In addition to Lazy Load, there are many other site optimization techniques to consider:

• CSS and JavaScript compression: Reducing the size of CSS and JavaScript files can significantly speed up page load times.
• Using Content Delivery Network (CDN): A CDN is a distributed system of servers that allows faster delivery of content to users around the world.
• Minimize HTTP requests: the fewer requests to the server, the faster the page loads. It is a good idea to minimize the number of HTTP requests per page.

Summary

Implementing Lazy Load on a website is one step towards a great user experience and better website performance. By delaying the loading of certain resources, you can significantly speed up the loading time of your site, which will satisfy users and positively affect your site’s position in search results.
