PRO's and CON's of Lazy Loading

Before implementing Lazy Loading on your page, you should carefully consider the pros and cons for your programming and website users.

Here are some of the advantages of Lazy Loading:

  • Lazy Loading strikes a balance between optimizing the delivery of content and simplifying the user experience.
  • Users can view the content of the page very quickly.
  • Due to faster page loading, leads to better conversions and higher revenue for e-commerce sites.
  • Use of less bandwidth, which translates into cost savings.

Some of the disadvantages of Lazy Loading are as follows:

  • Additional lines of Javascript to implement lazy loading, combined with existing code, make it more complicated.
  • Improper indexing of unloaded content can sometimes affect the ranking of the website in search engines.


  • Lazy loading is an exercise of loading the content of a web page, which makes it useful to improve the performance of the system and save your resources. The advantage of lazy loading is that it reduces the initial loading time of a webpage.

    Lazy loading reduces the weight of web pages and contributes to faster loading.

  • A Lazy Loading Image means the slow loading of images on websites, this means that if a user does not scroll the webpage completely, the images at the bottom of the page will also not load.
  • As the name suggests, the content is loaded continuously as the user scrolls the web page. As the user scrolls through the page, the images in the viewport are replaced by thumbnails and after a specified number of images are displayed, a button pops up allowing the user to load additional images.


Lastly, lazy loading is a great strategy that reduces the initial loading time of web applications to a great extent. However, to use this strategy, as a web designer, it is important to be properly aware of its negative effects while developing any programming.

A right and usable application will ensure better user experiences. It is important to have the well-organized web content for a good browsing experience. Lazy Loading technology speeds up the loading of a website, while also saving bandwidth.
