What is Lazy Loading?
Lazy loading is a technique used by web developers to improve the loading speed of a website by strategically loading content as it becomes visible to the user.
It specifically refers to the loading of images on a webpage.
Usually, when a webpage loads, all the images on that page are loaded simultaneously, leading to slower page load time, especially on pages with numerous photos.
However, with lazy loading and the best image compression tools in hands, images are only loaded when needed, i.e., when they are about to be displayed on the screen. It reduces the initial page load time of a webpage and improves the overall user experience.
So, instead of waiting for all the images to load before seeing the content, lazy loading allows users to view the necessary content first and only load the placeholder images they need.
Lazy Loading vs Eager Loading.
Lazy Loading and Eager Loading are two approaches used in web development to optimize the loading time and improve user experience.
Let's take a closer look at the differences between the two:
Lazy Loading:
- Lazy Loading is a technique where only the necessary data is loaded initially, and additional data is loaded as needed.
- It is commonly used for websites that have large amounts of content or complex features.
- Lazy Loading helps to reduce the initial load time of a website by loading only the essential components.
- It improves page speed and performance, making the website feel faster to the user.
- Lazy Loading is ideal for situations where not all content is required or viewed immediately.
Eager Loading:
Eager Loading is the opposite of lazy loading. It loads all the necessary data upfront, even if it is optional.
- It is commonly used when the entire data set is required for a particular page or feature.
- Eager Loading ensures that all the content is available from the start, eliminating the need for additional requests later.
- It can improve the user experience when browsing through large sets of data or when accessing multiple pages that rely on the same data.
- Eager Loading is suitable for situations where all the data is needed upfront or where the user is expected to access different parts of the website continuously.
In summary, the main difference between Lazy Loading and Eager Loading lies in the timing of data loading.
Lazy Loading loads data as needed, reducing initial load time and improving performance.
Eager Loading preloads data, ensuring it's readily available.
Why is Lazy Load Used in Web Pages?
Lazy load is used to improve pages, optimize loading speed, and improve user experience.
It is beneficial when dealing with large images or media files that can significantly slow down the page loading time. By implementing lazy load, the browser only loads the content visible to the user initially and then loads the rest as the user scrolls down the page.
By employing a combination of HTML, CSS, and JavaScript, web developers can ensure that data appears immediately once its retrieval state has been initiated. Lazy loading can dramatically reduce the initial loading time, as it delays the loading of off-screen content until it is needed.
This enhances the page's performance and reduces the amount of data that needs to be downloaded, making it an effective strategy for improving website speed and SEO rankings.
How Does Lazy Loading Impact SEO Ranking?
This can have a positive impact on SEO ranking for several reasons.
Firstly, faster loading times are a known ranking factor for search engines.
By implementing lazy loading, you can significantly improve the speed at which your website loads, resulting in a better user experience and potentially increasing your organic traffic rank higher in search engines.
Additionally, lazy loading can also improve the overall performance of your website, as it reduces the amount of data that needs to be loaded initially. This can lead to lower bounce rates and increased engagement, which are also essential SEO considerations.
Adopting lazy loading can enhance your website's loading speed and performance, boosting your SEO ranking.
Is Lazy loading good for SEO?
Lazy loading is beneficial for SEO as it contributes to faster page load times, a crucial factor in search engine rankings.
Implementing lazy load correctly can improve your website's SEO performance. The native lazy load feature, for example, keeps the src property visible to search engines, allowing them to index the images properly.
You may also use the best Image compression software to compress image file size for faster loading.
Including an src attribute as a fallback for the srcset property is also recommended, as not all search engines can read it.
An image sitemap can also ensure that search engines correctly index your lazy-loaded images. While some search engine crawlers can execute JavaScript and work well with lazy loading, others do not.
Including a regular image with a populated src tag inside a tag is advisable to cover all bases.
When implemented correctly, lazy loading does not negatively impact SEO and can even enhance your website's performance in search engine rankings.

How to Check if Lazy Loading Is Working.
You can perform simple steps to check if lazy loading is working on your website.
First, you can load your webpage and then observe the initial page load. If the images are not loaded right away, it indicates that lazy loading might be implemented.
To see lazy loading in action, open the Chrome Dev tool by right-clicking on your page and clicking on Inspect > Network > IMG.
Secondly, Refresh and scroll down the page and pay attention to the images that come into view.
If the images load only when they are about to become visible, it confirms that image lazy loading is functioning correctly.
By checking these two factors, you can determine if lazy loading optimizes your website's performance.
