Optimizing images for websites is a crucial step for website owners, web developers, and digital marketers alike. You don’t want Google to dislike your website. According to the 2022-2024 HTTP Archive, images comprised as much as 50% of average bytes downloaded by web visitors. Reducing page load times and improving the user experience can help you rank higher on Google. That is why I will introduce the importance of image optimization and how to do the optimization properly. In this article, we’ll explore various techniques to optimize images for the website, boost your site’s loading speed, and improve your search engine ranking.

The Concept to Optimize Images for Websites

Years before, in 2018, Google had already announced that mobile search algorithms would begin to consider page load speedAnd in those algorithms, one is explicitly pointing out that too many images not optimized for screen size can seriously influence the speed of web pages. As a result, the website will be down the right, even published. But, optimizing images for websites is to reduce the size of an image without sacrificing the quality so that your web page load time will get faster. Remember – Speed is everything.

Why It Is Crucial to Optimize Website Images

Generally speaking, pictures without optimization can make up about three-quarters of a webpage, negatively influencing your website. Search engines like Google prioritize fast-loading websites. If you optimize the images before uploading, not only will it reduce the total size, but it will also enhance the webpage performance and lead to the following benefits:

  • Improved loading speed
  • Better browsing experience
  • Optimized search performance

Furthermore, it is also an SEO factor. Typically, people only consider compressing and converting images when discussing optimizing images. However, they often neglect the problem that duplicate content may be punished according to Google’s rule. Of course, this also includes pictures. Image plagiarism was rampant during the advanced Internet age. What’s worse, Google has found there are two highly similar content and gives them punished by its automatic algorithms. There is no turning back, even if you can prove you are the first to publish the content. It’s just not worth it. So, it is the key strategy to deliver creative and original content and optimize images.
