How Can Image Optimization Help Improve Website Performance?

by | Published on Mar 23, 2023 | SEO

The importance of having images on websites has been increasing over time. Regarded as one of the most essential elements of a website, images provide visitors with a clearer vision of what a website is about. On an average, around 64 percent of a website’s weight is comprised of images, according to HTTP Archive. When it comes to search engine optimization (SEO), websites with images generate more traffic than websites containing pure text. In fact, they work even better if images are optimized correctly. Reducing the size of images without reducing the image quality can have a direct and positive impact on page load speed and user experience. Optimized websites and images are critical for maintaining user engagement and improving site performance. By implementing a few changes to the current image process, a website can gain more traffic and leads, resulting in more sales. An organic SEO company can help businesses optimize their images and improve website traffic and user engagement.

The basic goal of image optimization is to reduce the file size of an image without sacrificing quality. Optimized images consume fewer resources, load faster, and positively impact SEO. On the other hand, non-optimized images can consume storage space and lower a site’s loading speed. In fact, roughly 39 percent of visitors will likely leave a website due to a slow image loading time. Image optimization is the key to improve a website’s overall performance and provide a better experience for visitors.

  • Enhances user engagement – Optimized images have proper title and alt text, which are used by both search engines and screen readers in order to understand the context of the image. Page load speed is directly related to SEO ranking and conversions.

Website visitors will also benefit as optimized images will reduce the page load time. In addition, it will take significantly less time to backup a small website.
  • Saves Server Memory – Image optimization plays a crucial role in saving server memory and reduces extra server load. For example, if a website has two same images, one image size is 900kb and another image size is 340kb, using the second image will put low weight on the server, thereby saving bandwidth.
  • Supports Other SEO Efforts – Image optimization supports other SEO efforts. A well-optimized image can improve page engagement and increase the chances of an image showing up in the image carousels on search engines. Incorporating the right combination of format, title, title text, alt and text can enable images to perform well in search results. At the same time, a page with relevant content and images that are optimized can earn a higher number of social shares and even backlinks from other sites.
